SOURCE: tv is (bowing) rainbow effect, now turns on for second then shuts off

I had the same problem. The issue may be the same although I am not sure the powering off is related to the convergence issue. This is what I did: 1. Order the STK392-570 convergence IC and heat sink thermal transfer paste( I silicone based)..(make sure it is a reputable company so you don't risk getting bad components, I got them from an electronics supplier in MD) 2. UNPLUG YOUR TV AND ALL COMPONENTS!!!! 3. Remove the back cover and black plastic cover. (retain all parts) 4. remove the retaining bolts and screws on the black plastic tray (they are on the sides verticle mounted and front center as you are looking down on the tray.) This allows the tray to slide out like a keyboard on a computer desk. DONT PULL IT OUT YET!!!! 5. Just above the boards there is a shade board that slides out. Carefully pull it out. 6. You will have to unplug all cables ON THE BOARDS except for the RED ONES ON THE FAR RIGHT and provide tension relief for the cables by carefully unraveling them. The cables are marked on the connector and match to the markings on the board (I.E. KM, all connectors are marked with a two letter designation) Just disconnect the cables from all the boards and nothing elese. 7. Now carefully slide the tray about half way so you can see the contents of the entire center board. This is the board you need. Look in the back center of the board. There is a really large heat sink. The ICs are on the back side of this heat sink. They are held in place by a retaining bar that sandwiches the heat sink to the ICs. 8. There are some connectors on three sides of the board that are flat and white. CAREFULLY ....AND I MEAN CAREFULLY pull the left (as you are looking at board) ones up and disconnect from the center board. The ones on the right (I think they disconnect from the right board). 9. Unscrew the board from the plastic tray. There are a lot of them around the perimeter and center as well as the ones that hold the heat sink onto the board ( they also hold the board onto the tray.) You have to remove the "sandwich bar" (refer to 7)in order to get at the screws that hold the heat sink to board. (you have to unscrew them. 10. There is a box shaped cover on the left front part of this board that is screwed onto board and is also part of the retension to the plastic board, remove it to. (always remember to be careful when tugging, unscrewing, ect as it could result in breaking somthing) 11. There are black plastic tabs to the rear of the board. Unhook those and CAREFULLY lift and pivot the board forward and then up and out. 12. Now comes the easy part. You may have to pry the heat sink from the ICs carefully because of heat sink paste. Clean off the heat sink (dont use cleaner, just wipe the old grease off) 13. Use a good soldering iron (PACE, regulated, good desoldering iron) The temp just needs to be high enough to heat solder. 14. MAKE SURE YOU REMOVE THE CARD THAT WE TALKED ABOUT EARLIER that is in the front left of the board. You dont want it to break. Turn the board over so the chips are facing down. Take the desoldering tool and put it over the pins and in a circular motion until it heats the solder and push the sucker button. Do this to all of them that relate to the ICs. DONT KEEP IT TOO LONG ON BOARD. once you have done that to all pins, gentely tug on the chip wiggling it out. (carefully!!!!!) if you feel resistance desolder a little more. Make sure your desolder device is giving enough suction. 15. Now solder them back on and make sure you dont create any cold solder joints. This would be bad!!!! 16. Apply a decent amount of thermal heat transfer (grease, goo, ect) Make sure you do this or bad things will happen. You need this stuff. You can get it at radio shack. 17. Now put it back together and hurray you are done... Hope this helps... GOOD LUCK DJ

SOURCE: picture has rainbow effect

it sounds like the convergence IC's. You most likly will not find a complete convergence board to replace the entire board, unless you call PTS corp, at 1-800-844-7871, and see if they have any rebuilt convergence boards for this TV or if they can rebuild yours for you. There are no real user replaceable parts inside this TV set, so if you dont know how to solder and work on solid state printed circuit board, please play it safe and get a pro to assist you. Even if you get a rebuilt board, there is going to be some alighnment involved. Good Luck and please keep us informed of your progress with this repair.

SOURCE: rca 52w59 has a bowed screen and has a rainbow effect in color

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.

My son was bouncing a small ball against the screen and then it went to looking like a rainbow. Would this be the picture tube?


He may have caused some type of damage to the picture tube, but usually rainbow effects happen when magnets are present. Perhaps the ball became charged with a large amount of static, which then discharged across the tube, damaging the controlling circuits.

Tv screen is squeezed only straightens out if i bump the top of tv


This is likely your convergence IC solder connections. Does it look bowed and rainbow colored? The red, green, and blue will be mis-aligned causing a shadow effect. If you can bump it then the ICs (chips) are still ok, it just needs resoldering.
