Mitsubishi convergence issue


First is consider what the issue is: nothing moves convergence wise or only one color etc.

Also follow if needed the voltages from the pico fuses involved---one will be a negative voltage and the other a positive one--follow them from the diodes for each voltage to the chips---"Got Voltages?"

I can't find auto converge choice in menu of rca 52" rear projection tv.model # R 52 WH 74.


You have 3 pico fuses by your fly-back transformer. One of them blew that controls your convergence circuit. Your TV now thinks that it is a Basic CRT set with 1 tube. Find the bad fuse and replace with a 1/2 amp pico fuse, and re-solder all the pins of your fly-back transformer. Your menu should have the convergence option again.

I have a r56wh78 rca tv that the colors wont converge, can it be fixed


Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • 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.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc

Convergenc problems w/ RCA HD52W59 HDTV


sorry but u replace the incorec part , the board which control the convergence voltage on and off is the deflection board , now this board is about $100 - 150 , or if u want to fix it , just solder the flyback , just go to radio shack and get a 25watt solder station and solder rosin , also check for bad fuse , this fuse it dont look like the others , this is a 1/2 watt 250 pico fuse , and is next to the flyback , look like small brow squer little box , there is 3 and the one that is bad is the one in the middle , this 3 pico fuses are togethere u cant miss then , good look

Tv shut off and started clicking


Do you hear a constant chirp or click?

If so you will most likely need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

How to find the convergece amps


On that chassis the only fuse affecting convergence is a 400ma pico fuse near the flyback transformer. If this fuse is open the signal board will never send the "ON" command to the convergence supply so the convergence will be dead.
If the pico isn't open then suspect the amps themselves or possibly an open resistor or two.
