RCA 27V530T No Video
Been in electronics for years but focused on radio and communications.
Only minor work in television. My Sister gave me the following unit. It's a 2003 model that was working great. She turned it on a couple of weeks ago and now there is no video. Still get power LED and sound. No static on CRT at startup. She bought a new one and gave this one to me. Any suggestions appreciated. RCA/Thomson Model: 27V530T Service: 27V530TYX1 Chassis: ITC008FBK Thanks, GLW |

She had something connected to every input. Couldn't get a picture on
any ports. Homer J Simpson wrote: "Gary" wrote in message ups.com... My Sister gave me the following unit. It's a 2003 model that was working great.

Check the horizontal output transistor. |

Check for a small coil in the base of the H Output, bet there are lousy
solder connections on each end, seems the glue used to secure the coil to to pcb makes it very difficult to produce a good solder connection in production. Common Problem.

BTW: If there is a small PCC board on the right side of the chassis (Viewed
from back) check if there is a three pin connector going from the Main pcb to the PCC board. Cut the ends off, I.E. the plugs, and hard wire the PCC board to the Main board. Remove the black plastic plugs and pins at each location, solder the wires directly to the solder pads. Pay attentionto the colour rotation of the wires, it is easy to get them mixed up. ITC008 common problem. "Art" wrote in message . ..

Sorry for the delayed response. Been on vacation. I removed PCC board
connectors and resoldered wires. 1 to 1, 2 to 2, 3 to 3 on both ends. Same results. Also swapped out HOT, still a dead CRT. I looked for a small coil near the HOT output but there is only a medium sized one. resoldered it also. Same results.
