My RCA big screen TV picture now looks like 3D without the glasses. The picture also bows in at the top and bottom in the middle of the screen. What would cause this?

Looks like the focusing lens may have moved a bit or the projector lamp has gone weak. Get a technician to check up the projector.

There's very little you can do here.

This is normally an easy fix. I've fixed several of these. When you get the back off of the set, there are 3 small square brown fuses located at the back left corner of the set, if looking at it from the back. They are located next to the right side of the flyback transformer( the large gray or black thing sticking up with the thick red wire coming out of the top). One of those fuses will be open and needs to be replaced, and the pins on the flyback transformer need to be resoldered on the bottom of the board. They will come loose and make the fuse blow. This will fix the problem 95% of the time on this set.

You have a problem with convergence and all you may need to do is replace a fuse. Look up convergence for your tv model and hopefully you will get an answer as to where the fuse is located and how to replace it. Very common for RCA tv's

The convergence circuit is not working. It is way too difficult to fix by yourself but any-one who works on RCA TV's can fix this easily.

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

LOOK FOR OPEN FUSE (CTM) BY IHVT, THE MIDDLE ONE.

Go to Menu then setup look for convergence if you do not see convergence on menu then you have a open FUSE FL231 it is on right side of FBT flyback transfomer there is 3 of them small brown rectrangler looking caps it will be the one in the Middle.

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.

First check capacitors cp150 2200uf 16v and cp114,cp120 220uf 35v If cp150 is puffed up on top it is bad , then there is a fuse FL231 on right side of flyback transfomer it will be the middle fuse if open you will lose convergence on picture .

Replace 2 convergence chips, will start with stk ###-###
