SONY KV-29V11C power off immediately after switched ON

[rolexbc88]

Hi Everyone,

My Sony KV-29V11C goes off in a few seconds after switching on the power or right after the picture tube blinks.

Initially, the audio works ok but the video is dead. it went dead for a few days then while troubleshooting, i must have touched the loose connection (but never found it) and the video went ok but after two days working fine, while watching, it just went dead and the power goes off after switching on as the picture tube starts to turn on.

S. Diagram similar to KV-27S10, -27V10, -29RS10, -29RS10C, -29V10M, -32S10, -32S12, -29VTR15.

Any help, advise or info would be much appreciated. Thanks.
