Question about Panasonic PT-53TW53 53" Rear Projection HDTV-Ready Television

1 Answer

53 inch Panasonic tv would not turn on..red light blinks 3 times

You suggested replacing the 1 x 2.2 ohm watt metal film resistor for this problem... just wanted to make sure i have it right. Also what kind of tool will i need to get to put on the resister?

Just a regular solder Iron will do just unsolder the old resistor and solder in the new one

Hello, I have a 53-inch Panasonic PT-53WX42F TV, and it refuses to turn on. No picture, no sound. All it does is the tiny red power light blinks 3 times repeatedly. Can I fix this myself? What parts do I...


Thats a convergence failure when the led blinks 3 times. Your model uses the PT47WX42 convergence repair kit available from www.tvrepairworld.com the kit contains the parts and the CD with instructions for the repair.

The red led flashed 3 times and stops and then repeats the steps. I replaced both convergence IC's. I still have the same problem.


Did you replace the 2.2 ohm 2watt resistors. If the led blinks 3 times its almost always going to have at least 1 of the 2.2 ohm resistors blown.

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.

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

Magnavox 55'' Projection - Sides come in and out


sounds like Convergence issue.... I have some pictures of the bowing picture TV on the link below...

I'll post you my general message which is for a similar Philips Magnavox 51 inch TV, you'll need to check the manual verify the correct IC convergence chips and resistors, the manual link is below as well... usally the IC's are STK392-120's or 150's and the resistors are 6.8 ohm 12 of then...

anyway read the general post below it will get you headed in the right direction.

51MP392H/17

Actually I have this TV and you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!

Great reference link that I posted
pictures on, check out page 3

What you need:
(2) STK392-120 OR STK392-150 IC
chips
(12) 6.8 Ohm Metal Film resistors
set of star screw drivers
15 watt pencil solder pencil, DO NOT use a high watt iron you will fry the surface mounted item.
good leaded solder, and flux

Picture looks like it is in 3D


Yes you need to replace both convergence ICs. They are both STK392-150 you will also need to replace the 6 feed resistors. You will need ( two ) 1.8 ohm 1watt metal film resistors.
( one) 3.3 ohm 1watt, ( 0ne) 2.7 ohm 1watt, ( one) 4.7 ohm 1 watt, and ( one ) 2.2 ohm 1watt . The resistors are all 1 watt metal film resistors. You can get replacement ICs and resistors at the following link with free instalation instructions with pictures, plus free tech support.

Sudden shutdown - Red light blinking 3 times


Replace both convergence Ic's Stk392-110 and personally I'd use STK392-150's for greater reliability. Also check all 2.2 ohm 2w resistors for open or change in value and replace as many as needed...

Resistor


sorry I got the last4 letters in the part number wrong. Its a 100K 1/10 watt metal film but the part number is ERJ6GEYJ104V the other part number was for R7058 which is 3.3 K. Small print on the parts list. Order that number its for the 100k ohm resistor that you need.
