Check the speaker/s first. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

SOURCE: sony tv no pic or sound

Sony error codes usually only go up to 7. If the LED blinks 11 times, this usually indicates that either the clock or data line is shorted and this needs to be serviced by someone with experience with Sony sets.

Press and hold for a few Seconds the 2nd Button from the left on the front of the TV. The auto tune menu will appear on the bottom right of the screen. Wait until it disappears and then check the channels by using the buttons on the remote.

G'Day!

The TV can be fixed as long as the parts needed are still available from Sony. However, as far as trying to determine what part(s) are needed, I wouldn't listen to anyone other than a tech who's actually taken a look at the set or has worked on one with the exact same problem. If you make a call to a local repair shop, especially one that advertises repairing Sony, a nice guy will at least give you a ball park figure as to what the repair will cost you.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board

I have a Sony Trinitron model kv-a2921b. The TV


HELLO MIKE

I don't think your TV is totalled! It's more than possible that a speaker connection on the main board has come adrift and just needs pushing back in. Check connections on the speakers themselves and when you trace back the cables there will one or two push in connectors.

It may be a good idea to get the speaker connection plugs checked and resoldered. It is also possible that the fall could have jolted the audio IC and this should be checked for dry joints or cracked print on the board too.

Hope this helps (:-)

SONY WEGA PROBLEM


That doesn't make sense. When you state that the TV comes on 5 minutes later, doo you mean that you get sound right away but hte picture comes on later? If so, a :power board" won't help. Please update this so we can narrow down the problem and get you a solution.

Thanks,

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts

Sounds like the either the connection from the cable/sat box is loose or the board connecting the cables to the tv is loose. If you try unplugging and then reconnecting the cables and hold the cables in tight that might give you and idea. If you hold the cables in tight and the tv works right, then you know its your board. If thats the case the Tv needs to be serviced. Otherwise you might try using some other cables.

Sony KV-36XBR250 - no picture, good sound


This is a common failure mode (which I now share), and has nothing to do with the picture tube or surge protection. From the forums I have searched to-date, it appears to be a failed component in the flyback circuitry, but Sony will not admit to an inherent defect. If anyone has ACTUALLY FIXED this problem, please post a reply. Guessing won't help anyone. Thanks.
