Distorted picture on my 32" Proscan TV...(about 15 years old)

The RCA GE sets have a problem with bad solder connections in the tuner unit which also causes numerous symptoms including poor regulation, no vertical deflection, low audio or dead set.

Pulling in from the sides is either poor regulation or a bad eeprom/solder join issue

Hitachi 57SWX20B 3D Effect due to green light convergence problem

I'm trying to fix the issue on my 43FDX20B. So far, I'm able to move the lines up and down, but can't get the left/right motion to fix it. The attached link has the dynamic mode instructions, so you can correct this issue yourself.

The only thing I didn't have was the screen overlay jig the manual talks about. I decided to create one myself and use the screen as a beginning template. I went to our local hardware store and picked up some home window weather covering. The roll cost about $15, is a clear strong plastic and the template was very easy to create. I used a straight edge after I put dots on the plastic and measured the lines for being square and equal after I took it off my tv. Good thing is that if you don't like what you make the first time, you have a 25' roll to use to try again (ha).

Hitachi 51SWX20B Convergence problem


Your TV has a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in or warped.

Here is a quick test....

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

Try to adjust the 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.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.

Distorted picture

The RCA P52960 uses the PTK195 series chassis. There are 2 main boards at the bottom of the set and above the board on the right (when viewed from behind) is the convergence power supply board. This board usually has a big black IC on it, labeled STK730-010 and bolted to a metal heat sink. Chances are, that IC has burned out and stopped working. Replacing that IC should restore your convergence. If you do not have experience replacing IC's in projection sets, allow a qualified tech to handle it for you.

WS-55809 - Video pinched in center, distorted, yellow/blue/red glow

This doesn't sound like a programming issue. I had a very similar problem about 6 months ago and I fixed problem. I had cold solder joint on the video power board. It was the board in the middle. The power supply was to the right. The video board had a driver with a bunch of legs. About 7 solder joint where cold or loose. I solder the board and my mitsu wide screen was fixed. Hope this helps.
