Projection tv wont turn on

I have a Sony projection tv KP53v45. It is about 9 years old. It wont turn on. The stand by light just keeps flashing, no picture or sound. I took off the back but I don't know what I'm looking at. Is it worth attempting to repair?

    When I try to turn on the tv the green light flashes briefly then the red standby light starts flashing and doesn't stop. I can't get a picture or sound to come up.

    my akai pt5598hd red light blinks 10 times when I turn it on but then no picture or sound.

    I have a Sony KP-53XBR35 Rear Projection TV that continues to flash the red Timer/Standby LED about every 1 second, and I have no picture or sound. I have powered it down several times, even overnight, but when I power it back up, I have the same problem.

    I do not have a remote for this TV. My Grandson simply tried to turn the TV volume down on the front of the set when this happened.

    Can you tell me what this code means and what is necessary to fix it?



    Thanks,

    Jim A.

It's probable transistor output horizontal short-circuit and the power switching can't start because the limiter is on

It may be worth repairing, depending on exactly what the problem is. The flashing light on the front is a clue to where or what circuit possibly has a problem. That is a self diagnostics in this set. How many times does the light flash, and we can give you a better idea on what or where the problem is.

SOURCE: projection tv wont turn on

a sony should only blink up to 8 times. If its continuous without any pause that usually means No reply from the jungle (data bus is busy, shorted to ground or held
high), IK video path is defective.
Count your blinks again. let me know.

Hi,
4 times flash of standby light shows that TV has problem in Vertical Deflection area and possible causes are IC1509(V out) is broken and / or Q1505(V Pulse Buffer) is broken.
Please check / test above said IF you have experience of TV repair.
