TV arrived with a greenish screen at the top and the image jumping to black and white | After checking all the components, I didn't find a defect on the kinescope board, so I went to analyze the power supply board and found the rt801 to be faulty. Its function is to magnetize and demagnetize the power supply tube and coil. | Replace the 2-point RT801 thermistor for 1 3-point one and go out for a hug! | Jailson Lima |

When cold, the power supply was pulsing and the speaker was hiccuping. | Change the power supply capacitors c913 and c911 | When out of the socket, put a jet of cold air on the c913 c 911 capacitors and see if the power supply starts to pulse, then heat these capacitors with a thermal blower, if it turns on, then just replace the capacitors and go for it. | lucas-venzke |
