sony tv problems Model KV-32XBR55
okay this is the 2nd sony tv that is going bad on me this week.
 If some can tell me if this is worth fixing. It powers on fine, sound is fine but in about 10-15 mins, picture blacks out. Sometimes returns in 5-10 mins WITHOUT turning off set. Will have picture again if turn off set for 2-3 mins. worth fixing?? Thanks for reading. |

Could be a bad solder joint or a CRT getting weak. Check for bad solder
connections at the low voltage regulators and HDT, test and maybe restore the CRT and maybe it will last a while longer.

Do a Google Groups search for Sony, video blanking, blinking video,
etc. This has been covered lots of times here. David skype wrote: okay this is the 2nd sony tv that is going bad on me this week. If some can tell me if this is worth fixing.

This one sounds like bad solder connections on the vert output IC chip.
Probably an easy fix. |

Pull out the chassis and resolder all bad connections.
