Vistron 37 No model number stuck in standby

(1/3) > >>

Hi I have a problem with a Vistron 37" TV sorry there are no model numbers, but I need hel with what seems to be a usual fault.
The tv turns on to the blue standby light and nothing more, I have checked all the voltages from the PSU and all seem very good and on the button.

I keep coming across the main board having problems with the firmware having a mad fit, but I cannot find anywhere to sort the problem, has anyone had the same problems with this set, I believe it is the same with the 32 inch Vistron too.

The board I seem to be having problems with is HH.LCD-PCB.Y0-105 if that helps

Thanks for any help you can give on this one.

This is vestel chassis??????????

If power supply ok then could be eeprom

Hi S/D,

There's some back threads mentioning PS caps - a couple of 1000/10 and a 470/16 but no maker identified.

Pics are useful if you can't identify model or panel info - Chris.

Hi

Cheers Chris, all the caps are fine, all the voltages are all fine I am going down the same route as mulja, eeprom issues, the trouble is now is I cannot get any numbers off the back of the eeprom so I am struggling a little with this "Turkish Delight"  :41:

Hi Guys
 Sorry to intrude in discussion  but Having similar probs with my Vistron 37 inch-
suspect the same signals mainboard as mentioned (psu seems OK)
Can u mention the board ref of the eprom so can also try and identify it- will be U--- something
BTHW There is a supplier of blank /ready to burn eeproms on ebay (usually 16 pins ) although advert is  for laptops eproms -generically same chips and programming (?)

Thinking of reprogramming the identified  Vistron eprom   using a Samsung eprom chip dump (ie or another suitable .bin file)for 37 inch model via  the  TV 's serial interface port connected to  my laptop.
This is way I believe most corrupt eproms are corrected by TV Techs very  tricky but doable with patience
 otherwise swopping in proven Tv  eproms might be a solution  ?
 
Ur Info and comments  would be welcome  Cheers Les
