Conversion problem most likely. Do your conversion controls work both colors in all 4 directions.

Fuse was replaced and the tv works but the picture is in 3d and the top and bottom of the picture is bowed and also somewhat blurry

This is a suggestion: if convergence is off does the label on the back of the set indicate this is a PTK195 Chassis?

If so I can tell you the likely bad part and how to find it.

Before you rate this information let me know what you find.

I am here to help.

Help with RCA projection TV P46812BL (chasis ptk195AA)

You have probably blown one of the convergence ICs. Effectively the easiest thing to do is replacing the whole convergence board, so that no soldering is involved.

Here you can buy a replacement convergence board, just select your model.

Let me know if you need further help.

Convergience not working, three color pictures and concaved top and bottom. Is there a module that I can replace?

Check the small brown fuse FL231 located just to the lower right of the flyback. There are 3 small brown fuses. The middle one is FL231. Most likely it is blown. The reason it blows is because of the lead free solder used on the new boards. If you turn the board over you will probably find cracked solder joints on the flyback terminals. Re-solder all of the flyback terminals and replace the fuse if it is blown. This fuse tells the TV that it is a rear frojection TV and not a standard CRT

My RCA D52W26 projection Tv is blurry. Digital board replacement

You cannot replace it yourself sir because there are a lot of adjustments(electronically not mechanical) and you need an equipment to transfer the data from the old EEPROM to the new one. If the convergence is fine then the fuse should be ok..Picture is blurry??? 1. could be a dusty CRT lens, you can clean those 3 lenses by taking off the front speaker grill then there's a small hole that you can see the lenses... or the mirror needs to be cleaned also. 2. maybe it needs a convergence alignment, pls check your owner's manual if available. thanks:)

The set sounds like the convergence is not working. a fuse or two (small rectangular and brown) near the flyback transformer is probably blown.

RCA model P61950

fl231 is the convergence fuse, and is soldered to the board in proximity of the convergence ICS, on RCA rear projection TVs.

If fl231 has blown, TV usually does not turn on at al, if you get bowed picture, that means that the convergence ICs must be replaced.

The fuse is on the same board where you find convergence ICs, if the fuse had blown, or the pico fuses at the base of the STK convergence ics had blown, the STKs must be replaced.
There is need of purchasing the service manual to do the job.

The repair shuld be done by a technician.

This is the convergence IC, model may vary:

Blown fuse

You have a focus control located on the right side bottom of the set. Try adjusting that. If that doesn't work you could have a flyback transformer going bad.
