Question about Panasonic PT-47WXC43 47" Rear Projection Television

1 Answer

Conversion Problem Can somebody please help me with this ? I have changed the conversion IC's, worked for a while and then back to blinking 3 times. Checked the 1 Ohm resistors, they seem fine, the 2.2's Ohm next to the STK's, reads fine on the multimeter.Diodes, voltage regulator, they seem ok too. any idea what is blowing the STK's? Should I be looking at the video board instead of the power board? also would it be possible that the rom board is bad? Thank you

Did you remove one side of the resistors before checking them with the ohms meter? They have to be out of circuit to accurately check them. Also you need to be careful where you purchase the ICs as alot of places sell the chap chinese versions and they often fail within a few days. Heres a link where you can get quality ICs and resistors as well as free tech support.

Everything in picture has a red outline tried


Howdy,

It sounds like you are having a problem in the conversion circuit. The outputs IC’s for that circuit have failed and are need of replacement. The average cost is at least $450 on one trip. Call an Authorized Service Dealer for repair and estimate.

The conversion circuit is the circuit that aligns the picture.

Good Luck, Big Irish.

Tv turns on for 1 sec then shute off power light blinks 3 times panasonic pt53wx53g projection


Hi 3 blinks on panasonic is the conversion ics. very common repair for projectors. you need to replace two ics on mother board. The cost of the repair from a tv shop is 250,00.

At least now you Dont have to pay a service center to come out and diagnose
Just give them your model number and they can look up the parts. The job take 1 hour to do or so.

I hope this help thanks doctor video leadingedgeelectronics 1987
