You need the STK392-150 ICs not the 040s. The 150s seem to hold heat well and stay cool.

Sounds like a convergence IC issue. are the red and blue colors out of alignment making it look like 3 images? If so you need new Convergence ICs. You wil need two of them they cost about 10.00 each They are STK394-040 you can get them at the following link. It shows a picture of your ICs
If you need anything further please let me know.

Hi the problem you are having is a common one dont know what the repair bloke told you but your problem is with the convergance ic their are two of them located inside your telly the are located on two metal heatsinks sticking up out of the board the parts start with stk they might have a clip round them holfing them onto the heatsink these need removing to see the part number.
When you get the part number google it and it will locate the people who sells them part numbers for you these parts are not user repairable they should only be replaces by a pro as when you solder them in you cant let them overhear as this will blow the ics again but if you are confident in doing the repair then you will need a multimeter as well to check any resistors that might have also blown ok if you need further assistance let me know ok

Convergence box is out - the picture is like looking at a 3D movie without the glasses.

There are two common problems with these sets.

Problem #1) Convergence

  • Screen Looks 3D
  • Colors wont align
  • Video may look distorted
Problem #2 CRT Fluid has clouded over. Symtoms
  • Dull looking video
  • White looking video
  • Halos around objects
  • Red/Orange looking video

My rca 52'' flat screen tv

It sounds like your TV needs to be aligned. There should be a menu item in your setup menu called "Alignment". Once you choose this the system will either automatically align itself, or the screen will display a graphic that will allow you to align the guns manually. Normally you will move either up or down or side to side until 2 separate lines look like one.

Screen showing lots of colors caving in on top

You have no power to your convergence circuit. Depending on what model RCA you have will determine which parts are bad. Will cost about $200-$300 for a repair shop to repair.

Picture looks like 3D without 3D glasses on???

The cost I don't know, but this can be fixed. I'd say shop around a bit. Make sure the repair person is certified for your TV's manufacturer. There are generally 3 lamps in projection T.V.'s, Red, Green, and Blue. They have to be aligned for the TV to project a clear picture. A credible TV repairman should be able to fix it. Depending on if it's new enough to be under warranty they may cover it as well. Really the only reason to get rid of it is if you want to get a new TV anyway. Depends on the cost of having the lamps aligned.
