Title: Samsung LE37M87BD. Vertical & Horisontel coloured lines
Post by: zica on October 12, 2012,13:01:40

Hi!
Having problem with this set. Samsung LE37M87BDX/XEE.
The PSU voltages are correct, after i change 3 blown caps (24V and 5V standby).
The problem still remains.

This is what it looks like when i turn on the set:

When i press Menu it looks like this:

Could this be BGA ram problem? or even T-con?

Hi

Had an identical fault on the same model recently.

Changed the TCON , no result.

Sorry to say it was a faulty screen.
