Problems with green convergence

Hello, we've had a PT-53TW53 for over two years now with no problems. Then this afternoon we turned the tv on to watch the game and the green convergence was way off as everything seems to have "green outlines". There is also a green line arching across the bottom of the screen. (Our area was hit with heavy lightning storms last night but the TV worked fine in the morning.) Any idea what might be causing this and how costly it could be to repair? Any help would be greatly appreciated. John Z

Very common problem John with projection sets. They have High powered audio amps inside the sets to control the red,green, and blue convergence for the color alighnment on the screen. These amps blow out and should be replace all at one time. There are also resistors that can go out at the same time and your gonna have to have these replace also if they have any discoloration to them. This is not a job for the novice to attempt, as there are HI Voltage safety issues involved, and should be done by a trained tech. This repair should run you anywhere from $250.00 all the way up to $400.00 bucks, depending on where you live and who you get to repair the set. It's always better, in my opiniuon to call a factory authourized repair place as they should have all the service data and most parts for your set. Good Luck

Tv have a problems known as a convergence problems,it dead.The tv convergence board require to change 2 STK convergence ICS and some or all it resistors to solved the convergence problems.The shop will cost u $300-350 for parts and labors.
1answer comes on but everything has a red double or shadow..on the convergence page the red cross is way off the mark and moves some but nowhere near where it should be..the red cross starts to...

GO INTO THE CUSTOMER MENU AND SELECT CONVERGENCE--do not adjust the green which is the first option some of these sets offer---if you find red or blue are skewed and or will not adjust you have a CONVERGENCE circuit problem.

Considering if this is the case, total parts cost for the repair will be under 30 dollars if you can do it yourself, you can save the set and a lot of money--most shops get 300 or more for this type of repair.

Convergence problem with PT-53TW53... green and blue lines.

I would not do it, I had this issue before and the fix only lasted a few months then it happened again, sorry

Panasonic PT-53TW53; Red shadows appear and then the t.v. shuts down.

The convergence output IC's have failed. Only fix is to replace them. These are large amplifier IC's bolted to heatsinks and have a high failure rate in all projection sets.

I have my panasonic tv

This is a convergence problem and is either bad connections at the convergence IC or defective ICs. If you can solder, try resoldering the pins on teh convergence ICs. If that fails to resolve the problem, replace the ICs. These ICs are large black ICs attached to a heatsink and may be marked STKxxx.

Keep us posted on your progress.

sounds like the blue convergence IC is bad.This is quite common in all Projections units about 3 to 4 years old.

Tv has green outline

Hello fameus2,

Try to adjust your convergence from you menu items. If this does not work, the problem may be your convergence Correction ICs but make sure you try to adjust your convergence first. There is a lot of information on the net about how to change the two convergence ICs (so I will not reinvent the wheel here). I would however suggest that you get a qualified TV repair person to do this for you since some folks have run into other issues in trying to do it themselves.

I hope this helps,
Thank you,

I had the same problem i had the amps replaced, went up in size.

Open Questions:


Has anyone had problems with connecting an 'HDMI to HDMI + SPDIF + RCA L / R Audio Extractor Converter (HDMI input,HDMI+ Audio output)' to a Panasonic PT-53TW53? I have a TiVo Premiere hooked up to my Panasonic PT-53TW53. I use the HDMI out, and RCA R+L outputs on the TiVo, and hook up to the digital in connections on the TV. The conversion of the HDMI out is via an HDMI to DVI cable. This has worked perfectly for years, but recently I wanted to disconnect the TiVo and replace with my Roku or Amazon Fire TV. Both have a single HDMI output. So I purchased an AGPtek HDMI to HDMI + SPDIF + RCA L / R Audio Extractor Converter (HDMI input, HDMI+ Audio output) box, hooking up the HDMI output from the Roku or Fire TV to the input on the extractor/converter, and simply disconnecting the HDMI to DVI and RCA R+L outputs from the TiVo, and plugging them into the outputs on the converter/extractor. The converter/extractor has a 3 position switch: PASS, 2CH audio, or 5.1CH (via and SPDIF or Toslink cable). I have had 2 of these converter/extractors, and with both the Roku and Fire TV I got the same results with both converter/extractors: With the switch on 2CH, which is where I understand I should get HDMI video and 2CH RCA audio, all I get is the RCA audio. No video. If I switch to PASS I get video with no audio. Of course on the 5.1 setting I get nothing, since the TV does not support SPDIF. Yet I see reviews all over Amazon indicating folks are using this converter/extractor for this very purpose, and it is working fine. I can't possibly imagine that it is some sort of incompatibility issue with the TV, since the TiVo has worked (and continues to) fine for years. Any ideas?
