Question about Televison & Video

2 Answers

My problem is this. I have a panasonic pt-53tw53. The picture several weeks ago had the colors seperated. I replace the convergance chips with new ones. We turned the tv on and the picture was great for about 10 minutes. The colors began to separate again and then the tv went black and the power light began to blink. Last night I replace the 6 capacitor. They all read 2.2. The tv would not turn on and it smell like smoke. The power light was blinking. I want to take the board completly out to ck and redo my soldering. What might be the problem and how would I discharge the hight tension lead to be able to completely remove the board.

    Is there a system check for the main tv board. Example to check if the convergence chips have been installed correctly or if the new ones where good?

    This suggestion was helpful, so today I checked all my solder spots. The soldering job was not great but I made sure that there was no points connected etc. I cleaned around each solder. I re-connected everything. Turned the tv on and the power light stayed on for a couple of seconds. Here a pop and the power light began to blink three times, pause blink three times. Is it possible the the convergence chips that our new are bad? Thanks for your help

Did you not create a short circuit while you did the soldering? This may be the cause of smoke.

The correct way to discharge the high tension second anode lead is with a high voltage probe you can probably get one on ebay as we don't use them much anymore. Check your power supply for the proper ac to dc voltages as your problem sounds like a too high voltage being applied to your chroma (color) circuit causing your x-ray protection circuit to shut down your tv. If you must discharge the 2nd. anode without a probe: BE CAREFULL and, using an insulated wire of at least 10 gauge with an insulated alligator clip on each end; clip one end to an insulated blade screwdriver and, the other end to the metal frame of the tv, then: carefully one-handed: slip the screwdriver blade under the rubber suction cup on the crt tube until it touches the metal clip and, push the clip off the crt tube. The clip is a v-shaped wire wedged into a hole in the glass it must be compressed to come out.

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 color suddenly seperation went way off.


You can get the convergence repair kit at www.tvrepairworld.com which contains the parts and the CD which has the instructions and the service manual on it. You would need the PT53WX53 convergence kit.

Pt-47wx49e convergence problem


I just replaced the 2 convergance chips, but it did not seem to fix the problem. I then tested all the resistors that feed the convergence chips anf there was a 2.2 ohm fusable blown. IT was R7050 on mine. That seemed to fix it so that I could adjust all the colors through the convergence 2 screen. There seems to be a slight bow near the bottom when you look at the c2 screen, but not noticable when you are watching a picture. Since I got this broken, I am not sure how perfect it should be.

If anyone can send me the service manual, I would appretiate it. Thanks.

Panasonic PT-53TW53 53 in with bad picture


Sounds like you need new convergences ICs. There are two of them in your set sometimes you can get away with just replaceing one of them but I wouldn't recommend it. They are not too expensive are 15.00 each once you replace them you have to get into the service mode and adjust the convergence.
