I have a Sony KP-53HS10 TV for over 9 years. It still works great, good picture. But few weeks ago, it started making a "ssssssi" noise after turning on 4~5 minutes. The noise might come from a cooling fan...

There are no fan in this tv.This tv most common problems are the dead convergence board parts have problems,picture have colors lines R,B,G out of alignment,have colors shadows,and 3D pictures.The convergence board must have it 2 STK convergence ICS and some or all it resistors to be replaced to solved convergence problems.The problems u discribing,it a starting point,just the convergence problems,have not take it effect yet.Sooner or later ur tv will have the convergence problems.

Sony KP-53HS10 rear proj TV - picture goes on & off

If the adjustment of the screen settings does not fix your problem, its likely that one or more of the CRTs (picture tubes) is defective.

And, the CRTs for these sets are hard to find and expensive.

Standby Blinks 5 times. Picture goes off but sound stays on. Only hookup is Digital Cable - help!

Plug the electricity to a surge protector. I fixed my that way. Try it and let us know.
