Hi,
Working on a Samsung 50" Plasma TV that have been mounted too hard to the wall, so the backplate have pushed the Y-MAIN board and made a short.
One MOSFET have touched ground, maybe the GATE, four N MOSFET IXTK62N25 have been changed to similar MOSFET type. And a FUSE on the Y-MAIN board have been changed(Near the Vs power connector) Now there is picture buts is pink, and very bad..
When just turned on its looks like this:
After few secs its gets pink, you can see MENU etc badly
The black area goes away after some minutes.
What can be wrong?
The button locaten on the board in the middle, have been pussed, have it reset something? also there is some DIP switches EXT, INT etc - right now on EXT.
Model: Samsung HP-P5071 S50HW-XD03
50"HD D3.0 Y-MAIN
Some manuals here:
Someone have a scheme over the Y-MAIN board?
