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

1 Answer

Panasonic PT-53TW53 I've had this television for about 5 years now. I was watching tv this weekend just fine. I shut it off for about 15-30 mintues and when I turned it back on, I now have red lines going across the screen and arching upwards in the middle (kinda like the Bell curve). Additionally, a double image appears where the lines run through. I tried troubleshooting the covergence to no avail. I'm scared to call a repairpeson if I can fix it myself. Any ideas as to what's going on???

More than likely its your convergence amplifier ICs and if you can solder you can repair it yourself really easy.

The power light on my panasonic PT-53TW53 blinks 5 times in intervals. The TV set does not turn "on". Could you advise what this means ? Thank you for your help.

5 BLINKS means a short on the 140 volt line inside the set.

Usually this means the horizontal output transistor is shorted.

I can if you are able how to test for this and what to look for that may have caused this.

I am in California and online right now.

Problems with Panasonic PT-53TW53 replaced the STK392-110 with STK392-180's and the six resisters initially the tv worked fine but now and then i lose convergence then it works fine is this a heat problem...

It could be either a bad connection or a bad new chip--why did you go to 180 chip? The best replacement for the 110 chip this set used is a 150 chip. Keep in mind whatever chip you use they will only last 5-8 years---the problem is not the chip but the heat sink compound grease dries out from heat and whatever chip is in there is going to fail.

If you need further advice consult me--I have fixed hundreds of these sets--replacing with the original STK-392-110 you should get 5-8 years. If you got a new chip that is flakey you are going to have to replace both again to see if it is your problem

Let me know if you need help.

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.

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?
