From your description the flyback transformer has failed causing the high voltage to load down, if the TV is 10 years old or more, consideration should be given investing in a new set.

    Is it hard to change? I got the tv free and it is and 05 model and very nice looking so I dont mind fixing it , but if possible id like to fix it myself rather thend pay someone

    The part is a large black or gray transformer sitting on the right side of the set when the back cover is removed. There is a red lead that is attached to the picture tube with a suction cup, even with the TV unplugged it carries close to 40 thousand volts in the picture tube. The repair is difficult to do even for a tech and requires a lot of solder work, I strongly recommend a TV tech because of the dangers it involves and skills to perform the work.

this again sounds like the power supply,.if you hear a click when you push the power button, this means your main board is reading good so replace the power supply,.

TV WONT COME ON AND THE LIGHT KEEPS FLASHIN RED AN GREEN ON THE STANDBY BUTTON


  1. If your Sony Wega will not turn on, the front green light blinks, you hear a faint whirring sound and the green light turns red and flashes, it probably means the lamp inside the set is no longer working. If you noticed the screen beginning to dim in the preceding days or weeks, this most likely is the cause.

  2. If the green light flashes and the picture comes on momentarily but then goes off, and the green button flashes until the set restarts, then the seal around the lamp mount is loose and needs to be refitted.

  3. If the picture on your Grand Wega cuts in and out and the green standby light flashes, both of the set's STKs need to be replaced. STKs are small chips on your television's circuit boards and are identifiable by their labels. The specific STKs used in your Grand Wega TV will be identifiable by the numbered labels on top of the STKs.

  4. When you plug in your Sony Wega and hear a loud popping sound, it's probably caused by a defect in the high-voltage circuit. Let the professionals take care of this one.

  5. If, after turning on your Sony Wega, you can hear your set but the screen is black, you most likely need to replace your projection lamp.

Hi,
TV needs lamp replacement as existing lamp got weak or has been reached to end of its working life, please note that lamp is not dead or broken so that is why lamp lit is not lit at tv front.
Hope these info will help you.
Thanks.

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.

Red power light and buzzing sound with red lamp light.


My Sony lost its picture and had a flashing light. Unplugging for 36 hours solved the problem.

Sony FWD50PX2/S 50 in. Plasma Television power problem


It does sound like a power supply problem but that can be misleading because a problem somewhere else in the TV can be "holding down" the power supply. This can usually be determined by using some isolation techniques.

Tv wont turn on


How many times does the light flash, as there is a code that can give an indication as to what circuit is bad.
