Re: Samsung 48H8000 Curved - No picture, No backlight with sound
@budm, Thank You. Am checking the caps at the said board. The COF connectors looks pealing off. I don't have much hope reviving this TV.

Samsung 48H8000 Curved - No picture, No backlight with sound
Hello Friends,
This Tv comes with faults as follows:
No picture, No backlight and with sound.
When power cable to mainboard removed, backlight turns on.
So I replaced the mainboard, same result - No picture, No backlight and with sound.
Power cable to mainboard connected, disconnecting LVDS to T-con board backlight turns on, no picture with sound. Checking the fuse at T-con board all in order.
Removing 1 of 2 Flex cable going to LED panel from T-con board, backlight turns on, no picture with sound. Same result removing the 2nd flex... -

Re: HP W1907 No Picture
Hi Thanks for the reply, I've found a burn transistor (SMT) in the video board.
The board indicate PTB 1769 and not sure of the manufacturer, any idea where can I get a replacement. I'm in Singapore. ThanksLeave a comment:

HP W1907 No Picture
Before I write my problem I thanks the guys in this forum. I manage to repair my son's LCD monitor Benq Q7T3.
Now, I received this monitor HP W1907 yesterday which has only back light on (Very Bright ) but no picture. On dismantling the unit, found no bad caps (Visual) on the power board.
Can Someone help where to start from. Thanks in advance.
