Sony 37" LDK-37V5800

Hi All, Got this set from a relative to repair.  Tv powers up but no picture is displayed.  Backlight is not being turned on by mainboard. (If I unplug the link from mainboard to inverter the backlight comes on).  Tv responds to remote and green light flickers if channel is change. 

Just did not come back on after working fine?

I'm thinking mainboard.  And I cant seem to find a one for sale.  Would like to try software update on the existing mainbaord, but obviously cant access menu.  Is there a way to force a usb update?

Cheers For Any Help

Hi,
This is a common software problem, try:

See bulletin 09TV093.PDF, and choose software for
your TVs' screen size, chassis.
Regards.

Hi, Thanks for the info.

Still struggling though.  I have formatted a 2gb usb stick and followed the instructions, but it makes referance to another TB 10tv004 if you have the "Set Blocked" fault (which I have).  I have found the TB required but the 10tv004 TB has a program attached that is supposed to do a NVM recovery. 

Did what I though was correct but still no joy.

Do i have to format the stick a certain way?

Any help would be great.

Hi, Give up and bought a replacement board for a simlar model number.  hopefully i can flash it to the correct one using the supplied software.

Thanks Watteau for the info.
