I have a Sony XBR KV-32XBR55 bought in 1992. It

If you bought it new (model number indicated here is an older set) take it back----if used set someone will have to open it to see if fuse or power supply is the problem.

most likely it needs repiars, (replacement of capacitors in the power-supply.)primary and secondary side.
Or loose conections (dry joints)

Yes. There are other not broken TVs out there for good prices.

what's wrong with my Sony trinitron XBR tv's timer

you do have a deffective crt

i need a rc gide

can you turn on the tv manually? or with the original sony remote control
are you using the channel 3 or any video input to display the tv picture.
thanks

posible solution is adjust the screen to low.also check the trimer if it is working.check the resistor in the heater line...weng

I pressed "Demo" on the front of my TV and it worked, I have an old Sony KP-53XBR35 VIDEOSCOPE XBR - no original remote and the Universal remote has PIP button but would not shut it off.
Finally it's off!!!!

It's normal for new sets, especially Sonys to do that due to some sort of gas build-up in the new tube. My set still gets a high-pitched buzz after power on and lasts for a minute or two before silencing. If the hissing continues when the TV is turned off return it to the shop ASAP. It could be a problem with the power supply, something getting ready to blow up. Good luck
