Question about Panasonic PT-56TWD63 56 in. Rear Projection Television

Open Question

HELP NEEDED! When turning TV on, there is no picture, light flashes red three times, then TV turns off. I also need to replace the screen because someone decided to use an abrasive to clean it. HELP! Hello, I have a PT-56TWD63g doing the 3 blink thing. I've looked at both Panasonic convergence kits at the website you listed and neither kit description lists this model. Will one of these kits work? Does mine use the STK392-110 IC? Thanks, Mike

TV Tech - well another issue has cropped up today. The TV turns on for about 15 secs and then automatically shuts off. Seems like a power supply issue but not sure.. Your thoughts?

If you are removing a defective chip, can you just cut the pins carefully with a wire cutter and later apply heat to pull them off?

You have to pull the chasis completly out the set. Make sure you know where all the wires go that u have to unplug. Also u may need to change open resistors near the convergence amplifiers.

SOURCE: Hitachi 51G500A Convergence Problem

I have no experience at tv repair but I solved this problem and you can too. I bought 2 stk 392-150 chips made by sanyo on ebay for $30. I bought a low life jewelers loupe which is a sort of cap with different lens pieces out on the end of the bill for $10 on ebay. I bought a soldering iron and the smallest diameter silver solder and a little suction bulb and heat sink grease from radio shack for $20.

Take the back off tv. Locate circuit board with ics. remove screws that hold board . there are several wire bridges, snap these apart also. number connections with marker, undo connections. you will note that this board is connected to 3 crts by cable, do not disconnect this cable! This board must remain connected to crts by this cable! (so much for tv telling you how easy you can remove the board and solder it in your workshop) this board must remain connected to the crts, you can flip the board upside
down but all work must be done at back of tv

undo screws on ics. pry ics loose from heatsink. put on jewlwers loupe then turn board over and heat up each ic pin then **** molten solder into suction bulb. each ic has 19 pins. remove old ruined ics ( shame on Hitachi) my tv was only 3 years old! Put gob of heatsink grease on new ic, spread with razor blade, not to thick or thin, stick new ic thru holes in board and screw to heatsink . solder all pins to circuit board. look at the resistors that are close to the ics. if one is burned black it will have to be replaced, they act as circuit breakers and will burn out to protect other parts of the tv. usually the resistors are fine it was just the cheapshit hitachi ics that were bad.

Put everything back together and turn on tv for 20 min. after 20 min do the magic focus. your tv should focus up and be good as new. I have fixed several hitachi 51g500a in this way. Good luck!

I have a SONY KF-WE50 rear projection tv, a few weeks ago it started to turn the pic and sound off while the green light was flashing around 30 times. After the light finished flashing both the picture and...

the green is the reboot process and is normal.
the red light is an error code indicator.
count the blinks of the red cant be 30 times (I think)
it will blink a sequence, pause, then do it again for a total of three times.
count carefully, it gives you three chances to catch the number it is blinking.

Picture went out and red light on the front by power button is blinking. When I turn TV on I can hear sound but no picture,, then TV turns off automatically after a few seconds.

It seems problem with low screen voltage to three picture tubes in this rear projection tv.
If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue.
Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you.

Tv turns off and on

The first time my lamp needed replaced, the red light came on as well. This time my tv did the same thing, but after talking to my tv repair man he thought it was the lamp. He said that if you use your tv often then the lamp probaly needs to be changed after two or three years. I replacedmy bulb and it corrected the problem and I MUCH BETTER PICTURE.

need to know the model number as I have access to many different screen assemblies and also the 3 flashes is most likely a diagnostic code, so if you post the model number I will be able to help you out with both problems.
