Re: Technika 32" Failing to start with remote !

Ok a late up date when the tv fails to fire up and is flashing the led fault code the tv is acually on but the inverter isnt I could tell this by shining my led torch on the screen I could see my desktop background, so im a bit confused on whats wrong the psu, inverter or main board, weird or what ?

It's more likely that when the set crashes, it forgets to turn off the video output. The software for these is barely functional with many bugs and glitches, the digital tuner being the worst. I had one Vestel where if you entered the 7-day TV guide, the TV would shut off with the blinking light, but it left the backlight on, so you could slowly see the image fade away (as the T-con power was turned off.) I've had them crash when feeding them 1080p at 24Hz cinema framerate instead of 60Hz. etc. Bad software design and insufficient testing before release.

I have another video showing that when its started with the remote and it goes into fault mode the set is actually on but the inverter isn't I could tell this by shining a led torch at the screen and I could see the windows desktop, so could something be wrong with the circuit that tells the set to come on remotely ?

Yes it starts on what ever input/mode you turned it off in it does it on all inputs/modes, tomorrow I will open it and give it a good inspection esr the caps and check the psu ect, thank you.

Done the reset from rom but problem still persists.

Is there any way to get the set to NOT start initially on digital tuner mode. The digital tuner in these sets has a lot of bugs and can crash the set, leading to the flashing light.

Re: Technika 32" Failing to start with remote !

Ok I have done the reset and sort of narrowed down the problem when I did the reset I turned off my pc going to the hdmi and it powered on with the remote but when there is a signal going to hdmi it fails to start with the remote, I can do another youtube video if you would like to show whats happening as its hard to explain.
Edit still does the same thing with out hdmi.

Hard to tell from the photos, but it looks like a different main board unfortunately. Can still try a few things though.

Turn the TV on, switch to any SCART input. On the remote, press Menu then 4 7 2 5. It may take some attempts. The service menu should appear. Select the factory reset option and execute it. (The TV should turn off a few seconds later.)

I have had this issue before. It's an odd one. A bad capacitor on the main board. 17MB12 main board. If you post a photo of your board I can highlight which cap I replaced, assuming it's the same board.

Hello Tom66 thank you for the fast reply here are some photos, they arnt the best seen as I took them after I recapped the psu years ago and its too late to open the tv up now but I can get some better ones tomorrow if you cant tell from these photos if that the same/simmilar main board ?

Hello I have a 32" technika tv that has been running almost everyday since 25/12/07 it is a vestel manufactured tv and has a vestel 17pw20.1 psu (known to be junk) I replaced the capacitors on the psu around 2 years ago with rubycons. Anyway recently I have been experiencing a problem where the tv wont start at all with the remote (original remote) the power light flashes repeatedly and wont fire up but the tv will start with the side buttons and will run for a while but at random the tv will cut off and flash the power led just like it does with the remote issue. For some reason when powering on with the remote the voltage in the main capacitor completely goes but again with the side buttons the voltage in the main capacitor remains perfect and will fire on the set I haven't tested any of the components in the psu as it may not be a psu issue, if any one has any ideas please reply as this is driving me insane and I cant find anything on the internet, thank you.
