Re: Techwood 37722HD after PSU change still have no backlight
Ok. I will doublecheck, but there was 3 what have 8-10% from the others. Is it too much difference do you think?

pin 1&8= 2,2 Kohms
pin 4&5= 2,2 KOhms but there was 1 transformer where 2,0 KOhms ( I guess it is fine)
pin 5&8= 5,3 KOhms there was one where I measured 5,0 KOhmsLeave a comment:

These are the boards. This is a new PSU on the picture what I bought actually on ebay from a good seller. It was tested.
Thanks in advance for any idea!...Leave a comment:

There you go. These are from the Inverter. Do we need any more picture from any part?...Leave a comment:

Techwood 37722HD after PSU change still have no backlight
I have this LCD. Before the power board change, it was not turned on at all. I changed the PSU for a good one, and the symptome is the next: When the tellie turns on, we have a picture just for 1 sec, then the backlight turns off, but you can see the LCD picture from very close, so this means probably the inverter board or the ccfl is the fault. I guess for the inverter.
Have anybody a schematic for this tv or any idea what else can I check.
I will upload a few pictures soon.
Thank in advance for any idea! -
