    Sorry, typed an extra t in the model number. Yes that is the model I meant and I will check it out. Are the parts expensive? And is this something I could purchase thru

    Sorry, im not sure what the dc board is. There are two large boards with a smaller board mounted to one of them and then a small board for each projector lamp. Is it the smaller board within the larger board?

    I see a lot of heat sinks like the ones near that one but nothing like the one that is circled in the picture.

If you have already tried to adjust the convergence and cannot adjust it, then my money would be on blown STK amplifier ICs. There are usually two of them that need to be replaced along with the 12-15 resistors in the circuit. Please tell me the make and model of the set so that I can advise what replacements are to be used and how to replace them(requires soldering skills).

    Do you mean PT-53TW53G? Verify if the chassis is B19 coz I am not able to locate PT-53TWT53G. The IC is STK392-110. See the link below for the service manual, that should help you with the disassembly. The IC is located on the board that has the flyback transformer , from which two thick wires go into the CRTs. They are attached to aluminum heatsinks on that board. There should be two of them. You should replace both along with all the resistors in the circuit(see schematic on page 96. IC 2303 and IC 2302)

    Not the ICs are really inexpensive(should cost you about 15$ each) and the resistors are even more cheaper. You should also purchase thermal grease to apply to the new ICs before soldering them in. I would like you to verify the IC number before ordering though. The IC in the schematic shows 25 pin, which is not what 392-110 has. The number will be printed on the ICs themselves.

    Ok. Its not the A-board schematic that you should look for , but the DC-board schematic which is not in the schematic. IF you can get me the board markings of the resistors, I will check the parts list and can tell you what their values are so that you can purchase replacements.

    Have a look at this image. Do you see a heatsink like that?

  • eagle338
    eagle338 Jan 02, 2011

    Look behind each sinks for a black IC like the one shown image. It is covered(partly) with white paste which is the thermal glue. It has STK-392110 inscribed on it. If you cannot find it then get me high-res images of all the heatsinks so that I can find it for you. You can upload the images to and get me the direct links.

I have mitsubishi vs-50800 i was watching a movie and the screen just all of a sudden went blury and the color is all mixed up i went to the convergence menu and it wont allow me to move the colors left or...

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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. In some cases the TV will also not show any video. 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 projection 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 pics of convergence problems.



Common 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.

Panasonic pt-47wx53g red is out of convergence range

Have you moved the TV recently?, if so the red can(Red source) in the back bottom of the TV may have physically shifted in its holder, this is common when a rear projection tv is moved, jostled. Take the back off, look at the three cans,Red, Blue, Green, see if they all look like they are nested the same, bet the red is shifted a little.Good Luck with it!

You need to adjust screen drives on Red Green Blue tubes ,does all 3 of them light up? Focus/screen control box is in front of TV behind front panel Turn color off then adjust all 3 tubes to where you have a black and white looking picture, now turn color back on.

Tv went red and now power will not stay on

If one color goes out of control, the TV will auto turn off for safety reasons. Sounds like a red bias resistor has burned out. A tech will be needed to trace this problem. Sometimes there is a knob behind the front TV speaker panel for adjusting the color bias levels. You could try to mess with it if you are able to find it. I would just get a tech. Could be a cheap repair.

would require some troubleshooting, common problems would be convergence amp ic and high volt transformer transistors

Red Gun screwy!!

You have a typical convergence problem here that happens on just about every tube type projection TV set ever made. There are two STK IC's that will need to be changed. Best thing to do, if you have any soldering experience on printed circuit boards, would be to get the service manual, locate the convergence amp IC's order the correct parts and not any replacement IC's that cost less the 20 bucks, and change the IC's. If you have no solid state repair experience, play it safe and call in a pro to assist you in this repair. Good Luck

Rear projection tv

This sounds like the solder joints have cracked on one of the convergence IC's or the IC itself has gone bad. First determine which color has shifted inward on the left side (let's say red)and then find which output IC is labeled with that color and an H (RH) and resolder or replace that IC.

Color guns out of alignment

It sounds to me like the convergence amps themselves have failed. Ic7001 and Ic7002, both are STK392-110 Sanyo built Ic's and not an expensive job for a qualified shop. When shopping around for a shop to repair it ask what they charge for replacement of the convergence amps in this unit. And take the unit to them to save pickup and delivery charges...
Have a great day!
