Question about Proscan PS56670 56" Rear Projection Television

Proscan PS56670 56" rear projection TV

My TV was mfg in 1998. After the tv warms up the screen gets warped. This takes about 20 min. I had a tech look at it in Dec and at first he thought it was a convergence problem. After checking it out he thought it was a "pincusion" problem. With the rear cover off the tv worked perfectly until now. It will work fine if I put a fan behind it. Obviously there is some kind of thermal issue. I am not even sure if it is worth fixing. Can someone tell me what I should do. Is it worth fixing?

    Thank you. That is what I was figuring would be the best thing. I hoping I could find someone to take it for free. Might be worth it to someone who knows how to fix it.

For a 10 years old TV, it might not be worth fixing it. Save your money to get a new one once this one gives up.
I would keep it running using with the back cover off using that fan to keep it cool.
Hope this helps.

After tv is on for approx 20-30 mins it starts to make a loud high pitched squeal or whine. once turned off for approx 10-15 mins can turn it back on for another 20-30 mins before squeal will return....


Sounds like a problem I had with a Polaroid t.v. Take the cover off the back and look for capactors that are buldging on the top. The top should be slightly concave. If they are convex at all, you can buy new one at Radio Shack and replace them for under $5.00

Rodney, I see from your post on Dec. 20 that you have a service manual for the TV but it is in .dwg format. Autocad does offer a free browser plug-in for viewing the files. Thought you would like to know.

I believe the chassis you have is the RCA CTC211.

After about 30 min of tv playing, the screen begins getting blurry and discolored. when I turn it off for about 20 min. it will be fine again for about another 30 minutes. Sony trinitron wega Dec. 2001...


Not enough info, but I'll take a stab. What you are describing is known in our trade as a thermal, since it is related to the warm-up of your unit.

If your set is a triple gun CRT unit, the convergence ICs have probably come unsoldered and are making intermittent connections in there depending on the heat of warm-up. Those ICs generate a tremendous amount of heat and in CRT tech it is not unusual for their legs to come unsoldered, after years of expansion and contraction of the solder joints themselves.

Getting them resoldered again before the ICs go bad will get you out of the woods and back on track with completely reliable performance from then on, but until that happens you must not allow your set to stay running for any length of time in its bad condition. Doing so will croak your ICs and you will have to take the further step of getting them replaced and having your convergence retightened and possibly your geometry redone as well.

Toshiba 50h72 picture and sounds takes 20 min to warm up


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • 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.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.
