Hi there and welcome to Just Answer. Thanks for asking your question.


I'm going to need to know two key pieces of info in order to help you.


1. The actual model of the TV - written somewhere on the back.

2. How many times the standby LED blinks before pausing - it should repeat in a cycle.


Let me know and I'll get your info.

Steve, I'm on vacation for a week. I'll send the information requested in a week when I'm home.

Back from vacation. It's odd, but when I returned I turned on the TV and it worked. Used it a few days and its back to the original problem. Comes on, but flashes in standby.


So it is a

Sony FD Trinitron Wega, Model # XXXXX Serial #(NNN) NNN-NNNN/p>

Standby Light flashes 6 times, and then pauses and recycles for another 6 times.

This is a common problem. You will need to have the set looked at.


The 6 blinks indicates what is called a +B overvoltage, or +B overcurrent which causes the power supply to shut the TV down for safety.


A technician will be able to find the reason for the failure. I do think that you are probably looking at a $200 repair bill. Keep in mind that you can buy a new 32" TV for under $400.


I will be here if you need more info or have a follow up comment or question.
