    I have the same problem. We have a 2002 Sony Trinitron Wega. It keeps shutting off and the Stand By light blinks. I can hear the TV turning itself on and off. It is so frustrating.I don't feel comfortable working inside the TV set. How much will it cost me to have someone else fix the short?

    When I turn on the tv I don't get a picture and it says a " no signal" . Earlier today it finally came on. But this evening it won't . I smacked the side and it came on for a couple seconds and then went out. The picture in picture has worked thru all of this.

The 2 blinks are an indication of an over-current condition, otherwise known as a short. Typically this is because hte horizontal output transistor has failed. If you are comfortable with working inside the set and can solder, you should be able to resolve this yourself. Look for a large transistor (3-legged part) attached to a heatsink close to the flyback transformer (part with large red wire coming out the top). Post the marking on that part here and I'll give you the complete part number. Replace that part and you should be OK. If not, we'll need to investigate a bit more. The part should not be more than about $15.

Keep me posted.

    Yes it does help. . My Sony KV-XA25N90 have short Horizontal Output Transistor. Already check Diode surrounding the Horizontal Flyback and did'nt find shorted component that will cause the problem. I hope its only the HOT need to be replaced. Thanks. Dan

    I am not handy like this and I have the same issue. What would this cost to repair at a shop?

    Thanks!
