If it is yours and you are handy with in-circuit repairs, I would try and reference the parts and replace them.
I'm currently watching a Sony 36" XBR in my shop that was given to me by a client for free because it was too expensive too have repaired at a shop so it was replaced.
$17 later(two caps and a transister), it's up and running and has been for 5 years.
I wouldn't take the chance with a client however......
Every day is a good day.......some are just better than others!
Proud to say that my property is protected by a high speed wireless device!
