Question about Panasonic PT-53WX53 53" Rear Projection HDTV-Ready Television

1 Answer

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 on until circuit protection shuts power of (3-5 seconds). TV "Power on" LED fashes 3 times repeatedly until unplugged. I believe the resistor is a wirewound type. There is one brown or black ring on the end. Resistor is discolored from overheating. Do you have a schematic? Do you have any idea why the resistor would be overheating? I have read that the 3 blinking lights is a common problem, however the diagnosis for it was to replace convergence chips, someone else suggested relays. The TV is 4-5 years old and turned on quite a lot. It is identified as R7014 on IC board.

    This was the problem. I had already done some more research and identified the resistor. I have replaced R7014 and both STK392-110s. This fixed the problem. I just need to reset the convergence now.

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.

Panasonic pt-47wx53, no power, 3 blinks


3 blinks is indicating that the convergence has a problem The PT53WX53G convergence repair kit from www.tvrepairworld.com is the correct kit for your model. The kit contains the ICs, Resistors and the CD with repair instructions.

Television has double images like 3D, and bottom half of screen has a concaved image.


Hi,
Please replace convergence ICs in tv, there are two big black ICs that has number STK392-110 mounted with big aluminum heat sink, replacement these ICs will solve your tv problem. Also check big resistor nearby these convergence ICs and replace if found burn mark or color faded.
On circuit board, IC location number is IC7001 and IC7002
Let me know if you have additional question.
Thanks.

The red will not line up. What part do I need to replace?


Replace both STK392-110 Ics and check the six 2.2 ohm 2watt resistors. Heres a link to the repair kit for your model which contains both ICs and all six resistors plus step by step instructions with pictures on how to do the repair.

Convergence on lower half of the screen is off, green arc appears


Your TV most likely has a Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

Resistor identification


Hi fccjben;

The color code is as follows: blk = 0; brn =1; red = 2; orange = 3; yellow = 4; Green = 5: blue = 6; violet=7; Grey = 8; white = 9

Unfortunately, if it is wirewound, they usually printed the resistor value on the body of the resistor. For sure it shouldn't be glowing. Sorry I can't be more help, but without a schematid, can't do much else

Good luck Loringh

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

Resistor


electronix.com or matelectronic.com should have that resistor. Be sure to specify flame resistant 5% tolerance that is a convergence resistor so it needs to be flameproof and install it up off the board like the origional was.

PT-53WX42 IC replacement


The two convergence IC's are generic part# STK392-110 and Panasonic part# C5AA00000203. Also check for burnt or discolored resistors nearby. Since this is such an easy repair,a schematic is not necessary....The hardest part is identifying the burnt resistors and aligning the green convergence in the service menu.
