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

2 Answers

Resistor identification I need to identify the parameters (rating) of a resistor for a Panasonic PT53WX53G projector big screen tv. It burned up so I can not see the color codes on it. his 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.

    The resistor is identified on the IC board as R7014

The value of that resistor is 2.2 ohms, 5%, 2 watts. If that resistor is glowing, it could be due to shorted/defective IC7001,

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

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.

I have a DLP Panasonic tv. The lamp indicator is red.Does this mean the lamp will burn out soon. If so where can I BUT A NEW LAMP.


there could be a possible problem on the convergence module, this is very common problem on the projection tv, kindly check the resistor & capacitor on that area.

let me know,

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.

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.

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

Part identification


Thats a RCA You'll have a hard time finding the service manual to that. But when a resistor burns it usually means something else made it burn so you need to look into the cause or a new resistor will almost certainly fry as soon as you power up. Hope this helps.

You can try it, but through my experience, it just does not look good. You may not have a problem with it. Give it a shot. Good Luck.
