Question about Panasonic PT-51HX41 51" Rear Projection Television
Hiya Its a TX51P250 RP-TV that has the standard 3-blinks of power light, inspection of the D board revealed that 4 10R Resistors burnt out inline with the STK 392-110 modules, after replacing modules twice with new units ex USA, and have also replaced the resistors/rebuilt tracks, (new resistors are 0.6W not 0.25W) still get the 3 blinks on power on and protection mode clicking out.
Any suggestions for next steps? Nothing obvious has presented itself ie no further scorching,
Any assisistance is gratefully acknowledged in advance...
Just click below for convergence repair kit;
Double images and colors are blurry .Blue,red and yellow wave coming up from the bottom of the screen on the lower left symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change value,can caused truoble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is intallation guide including in the repair kit. Feel free to ask whatever the result... click the link for sample picture guide step by step installation;
Hope this may help;

Tips for a great answer:
Three blinks - B+
over voltage protection (OVP), unit goes to the standby mode then
displays the 3 blink fault. This is also a problem in the power
supply circuit, check T603 and R672.
