    WHEN I TURN THE TV ON IT TAKES FOREVER TO COME ON. I HAVE TO KEEP PUSHING THE UP and DOWN BUTTONS TOGET THE PICTURE TO FINALLY TUNE IN. WHEN THE TV IS OFF LONGER IT TAKES FOREVER TO GET BACK ON. SOMETIMES IT TAKES AN HOUR TO TUNE IN. ONCE ON IT SHOWS PRETTY CLEARLY, EXCEPT THE RIGHT SIDE OF THE SCREEN IS A LITTLE WAVY. IT STAYS ON FOR AWHILE AND THEN IT JUST BLINKS AND GOES OFF! I THEN HAVE TO START THE PROCESS ALL OVER AGAIN!

First place to start on this chasss is with a known failure in the horizontal circuit. there is a capacitor 2455 and 2 transistors locations 7461 and 7463 that have caused a wide variety of failures. i would recommend replacing these components before proceeding as they could be the whole of the problem.

Can dust build up on a picture tube's circuit board cause them to overheat and shut the tv down.


dust will not cause an issue like this in this type of set--RCA? it means a short of some type exists and the set shuts down or blanks the tubes--all you have described as far as appearance is normal.

RCA sets like this can be difficult to repair and also if you Google the model number you will see they have a lot of "problems".

We have an older Phillips Magnavox tv. The tv will turn on & we will see the picture for a short time but then the screen turns grey. We still have sound, just no picture. Also, the green power light...


Hello, the grey screen could be due to a missing 220Volt source which feeds the color (RBG cathodes)inside the CRT(picture tube). When this happens the beam current inside the CRT goes high in a matter of second, thus triggering the beam current protection circuit(blinking green light)shutting down the TV. Repairing the secondary voltage source is necessary to get the TV working normal, a good technician should be able to repair it for between 80 to 100 dollars parts included, except a picture tube, which could be also the cause of the problem(K-A shorts).

Projection TV keeps shutting down


Good Day;

Sounds like you have a bad green picture tube that has failed. To check this out; remove front speaker grill, remove small panel, you will see three CRT's (pictue tubes) sticking down, remove the little board on the middle tube then restore power. If TV stays on more then likely the CRT is bad but not always the driver on board could also be bad, check voltages.

Good Luck, big IRISH.

KP51ws500 turns green and shuts itslelf off


There may be several causes but, one is that when any color gun is being over driven, the Sony shuts down the gun to protect it. Try this. Remove the front of the set by removing the two screws from each lower corner. Next remove the black panel held on by 5 or 6 screws. Now you should see a panel with 6 potentiometers on it. Turning the ones on the bottom row CCW reduces the drive. Turn the color down and if all the guns stay lit, SLOWLY turn them up until you get the color balance that you like.

2. could be the vertical ic on the crt board

 

3. could be the focus pac.  located in front of tv with 6 adjustment knobs on it.
