A CRT (picture tube) for an RCA projection TV will cost $300-400 If the TV is more than 4-5 years old, you'll likely have to replace all 3 CRTs to obtain a watchable picture. Its probably not a good idea to spend that kind of money on a "free" TV.

I have an older model rca rear projection tv. The problem with the tv is that the picture bends into curve after about 5 minutes after it has been turned on. Please help.


Check the convergence IC's for cold solders, check for leaking capacitors in the area. Check the voltage regulator with a Variac.

Usually these sets just need the 2 big convergence IC's replaced with new ones. Clean all 3 picture tube lenses, mirror and screen. Get the original RCA remote that came with the set and MANUALLY align the convergence.

Rarely the bow on the bottom of the screen is not repairable.

Screen goes all blue


if it is a KP65ws500 it is one of a group of sets made by Sony where all the picture Tubes(set has a RED, Green, and Blue Tube.) ARE BAD. Most of these sets had all three tubes replaced during a program Sony had. The tubes are NO LONGER AVAILABLE---the only way to get one is remove the tube and send it out for rebuild---most of these cost about 250-300 just for the tube.

The set is shutting down because when the screen goes bright blue it detects one of the CRT's(tubes) is pulling way to much current.

The problem with Replacing your Blue Tube is cost and----sooner or later the other two(red and green) are going to fail also.

best advice is maybe not to fix it.

I replaced dozens of the tubes in these sets when Sony had a recall and provided the tubes for free and paid for the labor etc.

I know I am not giving you good news but I do this here for free and if this has been helpful give me a vote here. Thanks!

Sony big screen tv not playing picture after 5 minutes or so


You have a bad picture tube, or perhaps a picture tube drive problem.. To see what is bad, remove the front speaker grill under the screen in the front. Remove the screws that hold on the board that covers the front. Insidfe this set, WITH THE TV SET UNPLUGGED< Locate which one of the tubes is the blue one. Gently pull off the board from the end of the picture tube and swap it with the green tube right next to it. The green tube is always the middle tube. If the blue comes up again, then the blue tube is bad and you will most likely be better off to buy a new TV set. If the green comes up as the bright one, swap back the boards, call a tech and tell them there is a CRT driver board , or an RGB drive problem. This should not cost you an arm and a leg to get repaired. Good Luck, and let us know how you make out with the repair of this TV set.
