Two ways.
encompass.com (new screen) '
or try to find a use screen , try to find any tv repair shop, sometimes they have a use screen ( cheap).
Thank you

get an estimate to fix your convergence problem

The front controls are called Tac Switches. They have a tendency of becoming corroded and sending erroneous commands to the micro. You can disconnect the lead coming from the control panel to the chassis and see if it quits. If it does, that answers your question. If you decide to replace them all, try Encompassparts.com

i would like to first about which type of Television reciever u r unsing.

You need to replace the FL231, DL231 and CP230 You can get the parts and instructions at the following link cost about 12.00 total. The parts are listed under the RCA parts category.

You have a convergence problem. What is the brand and model.

Original remote stock # 240895 $38.69

If you will look I bet you'll find a switch on the back of the TV for internal or external speaker. It's probably gotten switched to EXT. somehow.

THis is very common on these sets. there is a special fuse thats cause this.. kinda hard to get rca part number 259213.. .4 amp. the reason this blows is there is bad solder connections on the flyback. so when you replace this fuse you have to resolder these connections. so if you know how to solder and can find this special fuse. it is a fast and easy repair

Yes, this is a convergence problem.

If it is going in and out or showing different symptoms from time to time, I am suspecting you have an intermittent problem as well.... Have you done the whacking test? Whack the set with your hand or fist; smack it a good one on the side, top, back, etc., to see if you can restore the picture. If the picture will restore - even if only for a few seconds, then you have a loose connection or a cold solder joint lurking inside somewhere. It may still be the convergence board or somewhere else that is effecting the color resolution lines; or you could have two problems: A) convergence board failure and B) intermittent condition from a cold solder joint either in the convergence board or elsewhere.

If you replace the convergence board be prepared to shell out some serious money. Usuall cost is around $150 to $400 depending on the unit and the labor and the other parts that may need replacing.

I, personally, don't like RCA brands because I believe they are not too reliable. So, if you repair it there is a high satistical probability that something else will go down soon thereafter. RCA in particular are prone to MTBF (Mean Time Between Failures) that catch up with it soon.

If you call a repair shop that is well trained in RCA big screens and describe the problem I think they can give you an easy estimation of what will be needed and how much it will cost.

goodluck,

A 1995 60 inch rca good picture and sound. Then it started a cracking noise and a hissing sound, then the picture went blurry. then it was nice picture and sound, then it died. took the back off and turned out the lights. Plugged the tv in and out from the wall socket and there was a sparking noise and a small arc when i plugged it in and out a few times ,at the part that the power plug plugs into.The white part that is beside the white power plug part has thick red wire coming out of it and goes into another plug that has more red wires in it. but the big white part beside the power plug part looks burnt and has black powder on it. that part is probably the problem but maybe not, what it the name of that part and how much would it cost and is it plugged in or soldered.

Try looking at the main board very near the flyback and you should see 3 fuse links (they look like hard capacitors) one of them is probably open causing lack or power to the convergence board by way of the ribbon seated close to the vertical output IC

Green really shouldn't be adjusted, you adjust red and blue to the green. When a color is bowed that indicates that a part or two are bad, probably the convergence output IC's and possibly a fuse or fusible resister. You may need a tech to come adjust it for you because after replacing IC's the adjustments should be done in the servicers menus not just in the consumers menus.

I had the same problem with mine. There are two voltage capacitors in there. A low and high. The hig voltage is bad. I had to have mine in the shop. Cost about $400

try adjusting the picture size.  Or the resolution.

ch over the power supply for the conv this is the stk730-020 that run your conv

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

use the remote that came with it when you bought it and go into channel menu and rescan your tv channels
