This can be a number of faults eg.no drive to one of the colour guns,or at worst a faulty crt you need a technician to find out.

Push power button and it stays on for a couple seconds and then shuts back off. No picture comes on. Thank you Jeanette


To determine what your problem is:

UNPLUG TV ANDTHEN PLUG BACK IN---TURNON---GREEN POWER LIGHT COMES ON FOR A MOMENT ANDGOES OFF.

PRESS AND HOLD "device" and "menu"buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

Let me know

Power on/off


that is a common problem with this rca's check the convergence board for a short circuit
more likely is a transistor or an convergence ic

Power button Flashes


For the first one, please list the model number and count the blinks. Also, can you please post each problem separately. It will get too confusing trying to address 3 sets with different but similar problems.
Thanks,
Dan

Is your picture somewhat weak ? This could be a problem with the picture tube . One thing you can try is to turn the screen control up just alittle at a time to see if the picture comes in . Once it does turn off and back on to see it it comes back on again . It might take 10 to 20 seconds but if it does your picture tube is weak . The control is on the flyback transformer it is the bottom control . Or it may be on the crt board on the picture tube . One thing to check once the picture comes is the video input . If you go to this mode and see faint white lines might want to try to turn the control down a little more to see if you can get them out and the picture stays on , if not thats how going to have to watch it . These picture tubes are expensive $500.00 to 700.00 depending on which one you have . One possible other thing if you tell me the picture was a great picture almost like brand new check the horizontal section for a loose connection as this will cause this problem . Don't get shocked and be carefull , Good luck

Hi: Sounds like it might be an overheating part, and the short is shutting of the set. Or it could be an intermittent connection in the pc board. Either case it would have to be repaired by a expert.
sorry.
