Re: rca p52927 chassis ptk 195 wont power up all of a...
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

TAKE A CLOSE LOOK AT THE LABEL ON THE BACK OF THE SET WITH THE MODEL NUMBER, IS IT MARKED PTK195?
THE PTK 195 uses a power supply mounted above the main boards and is about 10 inches wide and 4 inches deep.
It is very common on this model for one of the ten diodes to be shorted; confirm it is a 195 chassis and I will tell you how to locate the two diodes that fail. They supply voltage to the convergence circuit and I have seen dozens where one of them shorts.
Let me know what you find; is it a 195 chassis?
If this information has helped you rate this solution as I do this here for free, rate it "very helpful".
If it is a 195 chassis let me know and I will pinpoint the location of the two diodes and tell you how to check them.
You can adj. from the front panel of the set using the channel and vol. buttons,if the set you have has a ptk 195 chassis,check and make sure you have adj. projection tv in screens of the menu,in not the convergence power supply has failed,replace the reg on the board,part number is 215530
