You need 2 STK392-110 Convergence ICs and possibly 6 2.2 ohm 2watt resistors. You can get the convergence repair kit for your model from www.tvrepairworld.com the kit contains the ICs, resistors and the CD with instructions. The PT47WX42 convergence kit is the correct one for your model.

Panasonic cinema vision pt-53wx54j does not turn on. red power led blinks 3 times.


Hi


Thanks for using FixYa. 3 blinks means convergence output failure and to resolve this you’ll need to change the convergence chips which are located behind the black heat sink; you can see once you open the back off the TV. Please do rate the solution if the issue is resolved or post a comment for further assistance.

Thanks

My Panasonic tv pt53wx53g wont turn on it blinks 3 red lights


The 3 blinks is a error code for the convergence circuit. You can get the convergence repair kit for your model at the following link which contains both Convergence ICs and all six feed resistors and they include step by step instructions with pictures that show how to do the repair yourself. Heres a link to the proper kit for your model Panasonic.

I need to identify the parameters (rating) of a resistor for a Panasonic PT53WX53G projector big screen tv. It got hot so I can not see the color codes on it. This resistor glows red when TV is turned...


The resistor you see is a 2.2 ohm 2 watt resistor and is part of the convergence circuitry. I would replace R7011. 7012, 7013, 7014, 7015 & 7016 (all the same value) and the 2 STK392-110 Convergence ICs. This should fix your problem. You can find kits on-line for around $45 with the IC's and resistors together.
