Hello!! Good day!!! i only want to ask regarding on the Sony Trinitron model KV-1415WR. Somebody already repaired this t.v. and i notice that the D608 was missing.The L.E.D.power indicator is lit but it is still dead set. Do you know what is the value of this zener diode?Or can you kindly send me a copy of the schematic diagram of this Model?

some pro's and contra's...
Trinitron tubes are the best ever built picture tubes - long life, best contrast and sharpness, brilliant colors, etc thou u never get with any modern lcd screen. otherwise the big form factor is uncompareable with todays thin screens. also the brand itself and in your case the wega model is a name on its own high standard. anyway i would recommend you to let your tv check by a local service cause it sounds like a electronical problem - let them tell you how much aproximately fixing will count - before they repair it - so you still can decide is it worth or not. hope to helped a bit.
The 2X blink indicates that either the Horizontal output transistor is shorted, or the RGB amp is shorted (on the CV board).
The Horizontal output is probably the cause, and as a general rule, the flyback should be replaced along with the H-Out transistor. Good news is that Sony is pretty good about having parts in stock. In fact, a lot of times they will have the A board with all the parts on it for only a few bucks more than just the flyback, so you basically get a new TV (electronics-wise).
Any decent repair shop should help get the parts/do the repair for you if you don't have the electronic experience.
KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.
There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.
If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.
Sorry to take so long to get to you. Most sony Tuve TV's are pretty good performers for colour. If you are into that sort of thing, so can be worthwhile fixing. If it has power supply problems, may cost you up to $200 to fix. Rule of thumb, if repairs are more than half the replacement cost, it is uneconomic to repair.
Is your TV newly purchased ? When you bought that , had you ask the manuals, I do believe every units must have, no matter what brand or model it will be, CE required that act. So ask to your distributor or the store where you bought it unless , it has been passed from one owner to owner, or you bought this from somebody at lower price,,,,perhaps, maybe...but where is the manual? So I hope this reminder will help you... Pls. send feedback...thanks
