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.

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.
