Re: Technika 32" Failing to start with remote !

Got another one with the same issue, its a sanyo cd42ld33 with the same mobo but this has a 17pw16 psu and slave and master inverters. The set would fail to start with the remote and will shut the backlight down after it heated, but the Bl on voltage and 24v still persists but the led on the front flashes just like my technika did. So I decided to starting checking the inverters as they were darfons just like my technika and lone behold I find two 054n50's that generate the high current ready for the transformers tha were leaky and where heated just plain go open, I replaced them with the same parts off another inverter, the set fires on with the remote and runns fine for hours on end, been running and turning it on and off with the remote for hours. Wish I would have checked the inverter on the technika could have been simple but I over looked it as I had many tvs I could use in its place, wierd fault but thats vestel for you hope this helps.

I'd say stick it on gumtree for free or £10 so someone can fix it, it may be a bag of rubbish but if it can be saved from landfill, that would be best.

If you do want to fix the issue it's probably the little 15n capacitors near the transformer on the PSU, common fault on this model.

Just an update I have decided to replace the set with a 40inch lg or sony as I suspect the tcon is now at fault as the set went blank backlights turn on but nothing is displayed so im scrapping it for parts as im putting more money into it even though I was going to replace it at the end of the year got 7 years out of it so im not complaining, thank you all for your efforts.

I have a few spare 17pw20's so when I get home im just going to swap it out and maybe consider repairing it, all these problems come on at once surprised it lasted 7 years with out a single problem so I cant complain Im going to replace it at the end of the year.

Re: Technika 32" Failing to start with remote !

Got another problem now the tv will shut off during use, found that the 24v line is failing when it dies it causes the inverter to shut off and the speakers to crackle and the set remains in stby, tracked it back to the voltage reaching the rectifyer is too low and drops. Im just going to replace the psu, cant be bothered to track down the problem as I will be replacing the set at the end of the year.

If you put a Hitachi main board in this TV it will want a Hitachi-Vestel set of codes (they are slightly different.) You could try swapping EEPROM chip if it is in a socket. It's an 8 pin device mounted into a little socket.

All done swapped that little chip and it powers on fine now and all functions work, thank you all for you help I will post a youtube video showing it working.

Re: Technika 32" Failing to start with remote !

the remote should not need programing to the board at all if a genuine/replacement one have you tride the camera phone trick to see if the remote is transmitting? is the remote the genuine one for the tv or a universall one.The only other thing i can think of is maybe the cable from the main board to ir receiver is faulty?

see toms post
i forgot you may have used another tv brand/make mainboard i usually just order for the same tv brand/model

Re: Technika 32" Failing to start with remote !

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.

Man did you fix them or throw them out, im surprised mine lasted 6-7 years and its been used almost every day so it has about 5 years total use time, but im not ready to upgrade yet, just the usual vestel garbage.

Re: Technika 32" Failing to start with remote !

what the part number of the main board i will look and see if i have one in my box of spare boards.

Ok here is a picture of the board and other parts, I think the mother board is a 17mb22-2
When I multimeter the 24v going to the inverter it reads fine so Im kind of pushing the psu out of the picture.
