Technika LED32-248 Stuck in standby

(1/3) > >>

kumarj:
Hi, I would like help with this TV please. The TV has a constant red light. I have checked PSU and all voltages are correct (except I think my multi-meter needs replacing/calibrating).
So, I have checked all other boards and connected/disconnected ribbon/connectors and still no joy.
However, if I sit there and continue to cycle power switch and power button after 5-10 minutes the led will turn blue.
Sometimes it will stay blue until I switch it off but very occasionally the TV will come on and work perfectly.
The side buttons all work as they should at this time.
It will stay on until I switch it off and after that it stays on red standby again with the same fault.
Does this mean that the PSU is definitely ok? The caps all look ok and there is no noise or smell.
I am leaning towards the eeprom which I have read about on the net and wonder if this is the culprit?
So I am asking if anyone can help or am I barking up the wrong tree!

Thanks

Jet

Hi ,
I have same TV with stuck in standby problem.I couldn't get eeprom dump from same TV,for testing I write dump from Condor 32f311.Now Tv working fine but control buttons doesn't match meanings and I don't have original remote control to test all TV functions, universal remote doesn't work with TV.
If you have eeprom reader you can read the dump and send it me,I can test it in my TV.

Forgot to mention, Tv is not mine but my friend who has lost his remote.
I don't have an eeprom reader/writer as I only fix for family and friends now and again.
Do you think it is definitely the eeprom?

Hi Kumarj,

Eeproms usually either work, or they don't. As your set comes on at times, suspect the problem is elsewhere. Maybe try heating to see if it comes on sooner, then try isolate where heat makes a difference - Good luck - Chris.

Thanks for the info Chris. Thing is, as I have read in another forum, when I used a freezer spray (air duster upside down) on the u8 ic (the eeprom) it turns on more often and continues to work. I don't touch any other part of the tv, just the eeprom. So, I have purchased a second hand board to see if it will cure the problem and only then will I really know if it was the eeprom or not. If not, I will try your method of heating up.
