My sony tv 34 inches model kv34*90 become colors yellow


Hello
Just mention the full model number of your Sony TV. There will be some more letters follow [KV34-----]. Send it clearly to me by Fixya. Even though it is 34" TV, these suffixes are important for trouble shooting.OK.

I have no picture or audio on my TV. The green


It sure sounds like the mainpower supply problem, the power supply may be trying to turn itself off because it detects short circuits.

SONY KV-32S25 TV SHUT OFF...NO POWER NO SOUND


You have a blown fuse. It should be a GMA7 amp or a 5 amp. You could try to replace it and see if your TV works again. If it blows the fuse again, then there is something shorted causing the fuse to blow. Then call a good TV Tech.

I have a 2004 Sony Wega Trinitron KV-HS510 that will not turn on. When I try to turn on the TV it sounds like it will power up and then I hear a click, and the TV turns itself off. The Stand By Light is...


Hello,

7X blink is a generic Horizontal Deflection Stop code. There is a chip in the TV, IC8005 or 8006 if I'm correct, that routinely goes bad on these sets. It could be one of any number of transistors or IC's, but that one is usually the culprit.

The chip itself is around 40 dollars, and with labor, you're looking at about 125-175 average, barring any unforseen problems. That's in-shop. Tack on a service call charge if it is in-home (if anyone will do that for you).

Hope this helps you...

Sony KV34-HS510


TV's always make a clicking sound as the Main Power relay turns on. If you are asking why it then doesn't turn on, it can be many things. The processor monitors a number of circuits and if something is amiss, it turns off. The most common failure is the high-voltage circuit and if the set is any where near 10 years old, I'd plan on replacing the flyback transformer as well as anything else it damaged while failing.
Another option is to wholesale replace the main board from an outfit like PTS Electronics at ptscorp.com.
Hope Ya Fix It!

Clicking noise sony bravia kdl-40v3000


Normal 0 My kdl-46v4100 has been off all day and I've heard two or three clicks. It sounds exactly like the click you hear when it’s been off all day and you go to turn it on. A few minuets after it clicked I turned it on and to my surprise there was NO click sound.
This LCD TV (like most large displays) uses an Active Matrix of thin film transistors, aka TFT. Essentially the screen is a large array of transistors and capacitors. According to my previous observations; I suspect the random clicks are associated with the LCD circuitry providing a fresh “standby charge” to the TFT array (hence no click on power on following a “refresh”).

Not a solution, but an explanation other than “cooling off…”
