This Upgrade is corrupt the files in the zip file are not complete. It results in a checksum error. I have called ATS and they will look into the problem.

UPDATE: after extracting the file add a .zip extension and unzip it again.

This will result in the 2 correct files

So has anyone flashed this one yet? If so, is the sound glitch really gone?

Yes, I have successfully installed V1.1.1.6 , and it's still good for me.

However I never had the sound drops outs on my Harman Kardon AVR8500 HT receiver that some of you are experiencing.

Applied patch but still had about half a dozen droputs during Hot Auctions on Channel 7. Will monitor over the next couple of days.

I watched & listened to that show last night.....not one drop-out on my DTI1500HD and AVR8500 combo. (using digital coax)

Goes to show that there could be 'other' influences in your problem chain.....

1) Brisbane's CH70 broadcaster parameters ?

2) Broadcast interference ?

3) Antennae and cabling problems ?

4) STB to HT cabling problem ?

5) Home theater decoding problems? ....... this is a known issue as each manufacturer buys/subcontracts these components from various sources and therefore end up with different outcomes.

Does the problem manifest itself as another electrical device / light switch is being switched on / off in your residence ? This was discussed in much detail earlier in the forum....maybe early 2003, we discussed this influence / problem.

Im not aware of any of electrical device being switched on or off when the problem occurs but will pay closer attention over the next few days. It only seems to occur in the evening, at other times (morning and on weekends during the day) it doesnt seem to happen. Sound Output is via a Sony Amp connected via digital optical connection to Thomson STB. Maybe I can use the digital coax connection instead of optical and see whether that makes any difference.

Some users found that their 'in roof' antenna cable ran across 240v power/light cables in their ceiling. When electrical devices switch-on, the electrical spike generated RF along the power cable which was enough to interfere with the antenna signal.

Upon moving the antenna cable away from the AC power cable, the signal interference was reduced/removed

Secondly cheaper priced Digital Optical cable is made of plastic, not glass. The optical interface on plastic is not of the same quality as glass. This can cause jitter and CRC problems with the digital signal., which could manifest itself as signal degradation.

dugby,

Did a few tests last night and it seems that there is some type of electrical interference happening which causes the audio dropouts. My daugther turned the light on in her bedroom, bang, the audio dropped out. A little later I plugged my shaver in and turned it on and my wife said that the audio dropped out as well. What should I be looking at to try and improved my current setup? Could my coaxial cable in the roof be lying over some electrical cable?

Cheers

I guess the essential proof, is to plug a rabbit-ear antenna into the STB, with it's cable clear of any 240v, to prove that you can get an interference free broadcast.

Once proved.... the interference could be in the roof and the wall cavity......could even be at the back of your STB where all the TV/STB/HT cables are laying.

Obviously go for the more easily accessible cables first.

The roof can be messy, especially if there are AirCond-ducts & insulation hiding electrical cables. But up ther you will need to look for electrical, lighting and power to the AC blower. Also Air-cond butterfly valves run 240V. Essentially you need to trace the COAX from the antenna and keep it away from any other cables.

lets see how u go..

:blink: Hey guys.

i have a Thomson DTI 1500 HD. I connected up to my pc (Windows XP with the releveant cable and ran Hyper Terminal. Turned the Thomson on and off and on a dozen times but it didnt want to talk to me. I know its running version 1.1.1.4.

Has anyone else had the problem on the stb not talking to the PC?

:blink: Yep I do need it cause I have a lot of sound drop outs. Tonight happened on and off for around 8 minutes straight. Its really hard watching a movie when you miss every third word.

Hi Napalm

I loaded up firmware v1.1.1.6 to my thomo DTI 1500HD a few days ago via laptop - no problems. The intructions are quite detailed. Are you sure you followed the instructions exactly?

I am STILL getting sound & video drop outs with ch1/10/11/12/13/15, but not with other channels. For some reason ch1/10 is weaker signal than other channels, although they all transmit from same location.

Next move is to set up a new antenna close to TV - currently have a 25m run of 20yo RF cable from 20yo antenna which has bits broken off. Quite amazing that my pq is excellent apart from ch1/10 intermittent drop outs

best of luck

Hi:

I am still a noob in the digital television and have 3 problems, plz give some advice

1. My new Thomson DTI 1500 HD has regular digital audio drop outs on channel ten and sometimes channel nine(but rarely). It makes viewing movies unpleasant. although when using RCA analog audio, the dropout disappears.

2. Again Channel ten at night gets "loss of signal" and I would not be able to watch channel ten at night at all.

3. all of those problems are reinforced when in rain or bad weather....

I am using a 42 inch plasma, running on composite video , and coaxial audia cables. nothing too fancy. Currently living in a unit. the analog signals are quite decent, considering I am at the top level, and the unit itself is on the top of a hill.

Everything else works fine (other channels) now, should I replace my Thomson with something else? Since its still in 7 days as of now. Oh should i try this upgrade? Even tho many has said it hasn't worked for them. If I were to try to upgrade will any RS-232(C?) cable to USB work? The Thomson produces good PQ, but not as good as I would expected it would be (comparing to the displays they have at HN)

Thanks again guys, if some help and that would be appreciated. :blink:

i'm no expert myself but consider this:

1. My new Thomson DTI 1500 HD has regular digital audio drop outs on channel ten and sometimes channel nine(but rarely). It makes viewing movies unpleasant. although when using RCA analog audio, the dropout disappears.

2. Again Channel ten at night gets "loss of signal" and I would not be able to watch channel ten at night at all.

3. all of those problems are reinforced when in rain or bad weather....

what's the signal strength? go into the menu and have a look. (although it goes against poor weather) sometimes a 'too strong' signal can cause 'loss of signal' which is what i've experienced on fine-weather days, so had to insert an inline RF attenuator. you may be at the other extreme, with a poor signal.

I am using a 42 inch plasma, running on composite video , and coaxial audia cables. nothing too fancy.

The Thomson produces good PQ, but not as good as I would expected it would be (comparing to the displays they have at HN)

you really should at least try 'component video' output and experiment with the output resolution (using the switch combos on the rear). composite can produce a relatively poor picture with lots of 'noise' (eg: grainy picture and lack of colour saturation). do you have a SD or HD plasma? what's its resolution?

not sure about the firmware upgrade. if it's easy, try it.

howdy ruthless

your problems are very similar to mine - are you in Perth?

1. I get audio drop out with ch10 both thru RCA (direct to TV) and thru optical (via Denon AVR 1604). My video/audio drop out usually occurs simultaneously suggesting I have a signal problem, not STB or AVR problem.

2. Rarely get 'loss of signal'

3. Windy, wet weather makes it much worse and it spreads to other channels ( but my antenna shakes in the wind so I'm not surprised).

- Agree with shiny_car about the following

- check ch10 sig strength in comparison with other channels, via thomo menu. My ch10 sg strength is low compared with other channels, and I accept that to be the root of my problem. A forum member who lives south of me reports excellent reception on all channels with thomo 1500HD.

- check that thomo display mode settings are suitable for plasma (e.g. if HD try HD1 with M1, M2, M3)

- consider at least component video cable for best pq.

- Are you running audio from thomo thru AV receiver? The thomo firmware upgrade is only to support audio thru AVR's (usually via optical) and is unlikely to make any difference if your audio is direct to TV.

- To apply the firmware upgarde I used a male/female 9pin serial cable. USB cable - don't know.

I've had my thomo for a couple of months and I'm still on a steep learning curve!

good luck

Thanks "Kenno" and "shiny_car"

I actually live in Sydney suburban areas, and still gets bad signals :P , and yes I confirmed that channel 10 DO HAVE POOR signals(from the menu). See, then the problem itsn't on my AVR or STB. Also due to my noobness I mistaken component with composite, lol. So yes, I have been using component as of now, and I think they look ok, but not as vivid as plasma's on display in shops.

My plasma is a 42inch Panasonic ED which I got last year, but can support 1080i mode. (tho now I sorta regret why didn't I pay more for HD :blink: ) I can notice the difference when switch the modes on the back of my Thomson :P and I have a plain Sony AV reciever which accepts both optical and coaxial inputs.

Thanks guys for the advice, now I got few things cleared. which leaves me to some following options to improve my setup.

1. Try an indoor digital antenna which a powererd signal booster (as posted by few members on this forum).

2. Maybe other brand HD STB's will work better then a Thomson? But I do like the Thomson brand.

3. Last resort, just use the plain RCA audio output and put up with the sound..........

Are there anything else I might be able to try? looking for a cheap and quick fix.....

P.S. thanks again "kenno" on the RS-232 info, I'll look more into it, how are you coping with the audio dropout? Did the new firmware fixed your problem?

whilst upgrades in cables don't often yield startling benefits, your options would include:

*higher quality component cables: spend ~$40 at jaycar/DSE/jb and you'll get a 'good value' cable (eg: connexia, musica) that could improve the picture (not sure what you're using now); spending $100+ may or may not build on top of that, but probably not as good value and could be a waste of $$ if you see NO improvement

*change to a VGA (RGBHV) cable: if your tv accepts such an input (15 pin) then use this output on the thomson; i've never tried, but it is meant to be another step up from component; a decent 1-2m cable would cost ~$40 too

1. Try an indoor digital antenna which a powererd signal booster (as posted by few members on this forum).

maybe ring an antenna specialist and get a very rough idea on how much it would cost to install an antenna booster. there's probably varying grades/qualities of units, and it may cost a few hundred all up (booster + installation), but if you are receiving a weak signal, could be worth considering. or it may take an upgraded antenna, depending on what you've got.

3. Last resort, just use the plain RCA audio output and put up with the sound..........

that would be a very last resort! :P

try an optical connection to see if this helps, although again, may not, and probably not. a decent optical cable from jaycar may cost ~$20. but i suppose try the firmware upgrade first if you can manage to make it happen.

good luck :blink:

Hi All,

I'm having issues with drop outs that have never occured before and i thought i'd install the lasted firmware as a starting point and i remember that after installing 1.1.1.6, there was an even newer firware upgrade that i never persued as my current one had always worked well, unitl now. The website (now called thomson.net) is no longer supporting the DTi1500 HD and i can't find the newer firmware anyware.

Does anyone have a copy of this newer firmware they could email me?

Cheers

Frank
