Convergence problem


Usually what happens is that the convergence IC goes bad or the fuse going to the convergence ic goes bad. Pico fuses they are called sometimes open up. You may want to open it up and pull the board out and check the solder connections on the convergence IC. Sometimes these get fractured or cold soldered and aren't making connection to the PC board.
Let me know if you feel comfortable with pulling TV chassis out or pulling the board that has the convergence IC on it out. Then you can resolder convergence IC OR replace it.First thing i would do is check to make sure there is between 22vdc and 25vdc on the fuse or the convergence IC. Let me know if this helps out any.... Sincerely HDTV GURU JAY

Help with RCA projection TV P46812BL (chasis ptk195AA)


You have probably blown one of the convergence ICs. Effectively the easiest thing to do is replacing the whole convergence board, so that no soldering is involved.

Here you can buy a replacement convergence board, just select your model.

Let me know if you need further help.

Replaced convergence board but still out of convergence. what's next?


1- Did you try converging it by way of your menu?
2- Sometimes they have fuse-able resistors on the deflection board that go open when the IC's take a dive.
3- If this doesn't help then I will need your model number and make and you will need to get your DVM ready for trouble shooting.
4- I haven't had to replace a convergence board complete in 20 years, I don't know why your wanted to do that. Replace the IC's and possible resistors and your back in business.
5- Let me know!

Hitachi 43F300 convergence


Hello,
Do not replace whole convergence board.Because convergence data stored in old board cannot transfered to your new board.Means in your new board there is no convergence data.Unless you have the service manual and know how to get service menu.

I believe if you have convergence problem one of your IC (STK) is bad along with couple of small
Value resistance.

Dont forgat to Rate!

Good Luck

HC-P4752W - IC Replacement vs Convergence Module.


The colors weren't lining up correctly on my HC-P4752W which is only about 30 months old. I did a little bit of research and got ahold of the people at http://servicemanuals.vstore.ca/ They recommended replacing the IC's as well as the IC resistors. I purchased the replacement parts from their site and made the repairs myself. I should mention that I didn't have any previous soldering experience. The repair was easy and a complete success. You may find replacement parts elsewhere for slightly cheaper but what you won't find is the prompt and detailed customer service that they provide. They gave me there # and said to call if I had any questions before or during repair. I took advantage of their services and got answers every time I called.
