Replace the horizontal output transistor (Q502) and check the electrolytic caps in the vicinty, unsing an ESR meter. PLEASE NOTE THAT THE TV TUBE MIGHT BE CHARGE WITH ABOUT 27,000 VOLTS.

What is the tv remote code for sony trinitron tv kv-9pt40

actually there is no set code for your model number. if you buy a sony remote is all you need. but if you bought a universal one than look in the manual and try all the codes for sony if that does not work then you have to program it manually. but go and buy a sony brand remote. all sony remotes work with all sony tv so you do not have to program it.

Sony Model KV32HV600 No picture, no sound--red light flash on front of TV-tried disconnecting the power cord. works sometimes-usualy does not.

The red light on your unit is flashing b/c it is informing you that your unit is in need for a repair/replacement part. perhaps one of your boards are about to go completely out. Contact your manufacturer for warranty replacement or referral to local repairman.

Blinking Light 8x

8 blinks means an audio problem. It will either be the audio chip, or one of the amplifiers, or something in between.

Tried turning on my Sony and no picture no sound, just a black screen

Sony is known for having problems with the picture tube. Sometimes it will blink on and off. also bad connections on the main board. A CRT restorer will sometimes help with picture tube problems but this must be done by a tech that has one.
