Question about Panasonic PT-51G44 51" Rear Projection Television

1 Answer

Convergence issue i actually have a PT51G63 but cannot find it under the models... i bought it used about a week ago and it worked fine but had isues with really dark objects ... this morning i turned it on and the red is about an inch to the left of everything else... there is a mini-fridge to the left of the tv and i was wondering if that may have messed it up... i was also up for a late night of extreme awesome gaming on it last night... the thing is under convergence i try to change it but i no longer have the original remote ... i can get into the convergence menu using the buttons on the tv but the navi buttons act like normal volume/channel buttons while its open ( so instead of changing the convergence the volume just goes up or down or the channel changes ) what do i do !! ( besides buy a new tv please )

Re: convergence issue

You can go back to factory settings by pressing and holding the ACTION and POWER buttons on the TV while it is on. A CHK screen will appear and when it does release the buttons and then power the set off then on again. This had reset all settings back to factory conditions. You will have to reprogram any channels into memory after this.

53udx10b hitachi rear projection big screen. replaced convergence chips 2 months ago. Worked awesome. Started having power issues 3 weeks ago. Turn on - kicks right back off. Used to be able to turn...

Sounds like the problem started out with an intermittent solder connection possibly on the deflection PWB unless the power relay has a bad connection or is breaking down under load. If it is not the power relay, I would check the connections under the deflection board - paying close attention to the area from T701 and T752 including the Horizontal output Transistor for a short. You also have a possibility of defective filter capacitors causing the problem as well.

Thats a convergence failure issue. The Sony Type 1 convergence repair kit available from is the kit your model uses. The kit contains the parts and the CD with instructions.

My mitsubishi 60" screen turns on but has red-like waves. Is sound in background, but it shuts down, too. Anybody know what it might be. I just bought and moved it to my house two weeks ago. Worked fine...

This is a very common failure on Projection sets. Its called a convergence problem.

You may have one or more of the following symptoms.
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • No Audio / No Video - Makes Chirping Sounds

You can see some examples and find a fix here...

3 blinks means the convergence circuits are shutting the set down. Usually the convergence ICs will take care of the problem, but I would recommend getting the service manual from the following link, as they will provide you free support to help you diagnose why it wont start as usually the convergence ICs wont prevent a set from powering up, unless another component in the convergence circuit has failed.

You need to go to, enter your model number,look up under that model number STK #(@-560. Order Two of the part number 874901908. These also need heat sink grease in the back of these ICs when they are replaced. If you know how to solder, then good luck, and please be carefull!.. Please do not forget to rate this thread.

Toshiba model 61HX70 convergence issue

It is a good possibility you damaged something on that PCB that had the IC's, I like to use an upgraded chip the STK394-160e that is designed for HD signal stresses. I dont know why they ordered the convergence board but I suspect it would have been ok, there are also 2 jumpers that need soldering JW10 and JW50 that supply power to the chips and they REQUIRE resoldering or it will fail again. Might try reseating the RED CRT board, check for cables that you may have unhooked to see if they are not seated in their sockets properly, double check every wire you unhooked, Make sure you used a Silicone Heatsink Compound on to the back of the IC's. I dont know what all you unhooked, but check the wires going between the CRT Boards. Check for cracks in the boards to make sure they werent flexed to much. Good Luck.
