I PUT MY TV IN THE SHOP AND THEY REPALCED THE SYSTEM CONTROL CIRCUIT. MY UNDERSTANDING WAS THE EPROM. THE PERSON I GOT THE TV FROM HAD IT IN THE SHOP TWICE FOR THE SAME PROBLEM BEFORE I GOT IT. KNOW THE REMOTE WORKS WITH NO PROBLEM.

IF YOU HAVE TO UNPLUG THE T.V. TO GET IT TO RESTART, IT IS PROBABLY HIGH VOLTAGE SHUT DOWN. IT CAN BE THE FLYBACK TRANSFORMER OR POSSIBLE BE A SHORTED CRT.
DOES THE SET HAVE HIGH USAGE ON IT ? WAS IT A FLOOR MODLE ? IS IT WATCHED MORE THAN 4-6 HOURS A DAY ? YOU CAN DROP THE CRT BOARDS AND SEE IF IT STAYS ON. OR REMOVE THE HIGH VOLTAGE (RED ) LEADS OUT OF THE HIGH VOLTAGE BLOCK. MAKE SHURE YOU DON'T REMOVE THE ONE GOING INTO THE BLOCK. ONLY GOING OUT. ALSO CHECK FOR COOLANT LEAK ON THE BOARD. IF THE STK'S ARE ON A SEPRATE BOARD YOU CAN UNPLUG THE CONVERGENCE BOARD AND SEE IF IT STAYS ON.

On the back of the TV, you'll find the Access door to your lamp. Unplug the TV from power, and remove the screw on the access panel. Inside you'll find 2 additional screws holding in the lamp housing assembly. Remove the screws, then the lamp assembly and visibly inpect it. You'll know if the lamp is defective, it will have obvious damage. If so replace with part # 260962, you can acquire this lamp for arround 100 dollars off ebay, or 262.00 direct from RCA.
