Question about Sony FD Trinitron WEGA KV-20FS120 20" TV
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.
