Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
Any TV can have a bad solder connection problem after
moving.Unfortunately,the fix may not be easy.
1) pull light box out of cabinet or hire someone to do it
2) slide/tilt for servicing main PC board
3) examine solder connects with magnifier--solder any/all
bad connects,esp around microprocessor
4) Check horiz output xistor =if ok,re-assemble,test
If shorted,replace with first quality transistor and solder
any/all suspect connects in horiz drive circuit,then assemble
Let me know......T.
