    There are two model numbers: KDF-E55A20 and KDF-E60A20. A cable TV Technician said that the HDMI input was defective and that the TV did not recognize the DVR cable box. So, another input was tried and the same result: all picture and sound would cut out. Also, the pixels are dieing on the screen.

  • jpsamurphy May 25, 2011

    The picture and sound goes out for about 10 seconds and then comes back for 10 seconds and then repeats.

    I changed the lamp out in 2009 when the TV was 3 years old. The picture slowly faded over time but I never lost the sound. This time, picture and sound are lost for 10 seconds then they return. Green power indicator lamp flashes when I power up the TV and my neighbor tells me that is a code.

    I have a Sony Grand Wega LCD Projection TV (HD-TV) model numbers KDF-E55A20 and KDF-E60A20. Picture and sound goes off instantaneously for about 10 seconds and then comes back for about 10 seconds and then repeats. When it started months ago, it would happen once or twice a day. Sometimes, the green power indicator lamp will flash. Also, my pixels are dieing one at a time but that is another problem.

    That makes more sence. Thank you.

  • jpsamurphy May 25, 2011

    A bad capacitor makes more sence then a bad lamp. In my limited education in the field of electronics, I know that a capacitor holds and discharges power. Also, I changed out the lamp in 2009.

Good day!

You have a better chances if you have a failing capacitors on the power supply board.

Try to look the capacitors if have a leak or bulged on the top.If you found replaced it with the same type,ratings and value.


Thank you

Do you have the model number and what do you mean by rebooting? Is it cutting off and on?

    That is a typical symptom on Sony dlp's. Changed many a lamp that was blinking on and off. Just like the old flourescent lamps that used starters in the old day! Most likely you have a bad lamp. You can get a lamp with housing at www.pureglare.com Just type in the make and model number and it will probably be less than $100. To locate the lamp there is an access door either on one side or on the back...likely on the side. After removing the door the lamp will unplug. Plug up the new lamp and put the door back carefully.

    Take the lamp out and inspect it closely. Look particulary at the root of the filament stem in the center. If you see any bubble in the glass at the bottom there then the lamp IS BAD. The lamp indicator light if flashing is telling you that the lamp is bad too. Check your owners manual.

I have a 60 inch tv and i have white dots on the screen


that is what we call dead pixel, you can remove this by following the steps below.
  1. Turn off your tv.
  2. Get yourself a damp cloth, so that you don't scratch your screen.
  3. Apply pressure to the area where the dead pixel is. Do not put pressure anywhere else, as this may make more dead pixels.
  4. While applying pressure, turn on your tv screen.
  5. Remove pressure and the dead pixel should be gone. This works as the liquid in the liquid crystal has not spread into each little pixel. This liquid is used with the backlight on your monitor, allowing different amounts of light through which give off different colours.
    Hope this helps.

Hi andrew, its not a big problem.. Decent TV. but the pixels are DEAD. that means you have to recover them by fixing the LCD. this would cost you around £40-60 for a 32 inch TV. hope this helps!

I have two small blue spots on my big screen


you cant remove those spots as they are referred to as 'dead pixels'
im guessing your warranty is already finished, so you'll have to get in touch with the manufacturer and they might be able to give you a few names of places that can fix this in your area.
also, unfortunately, the only way you can prevent anymore would be to stop using that tv. :(

Horizontal (dashed) line across screen


On the KDFE55A20 this sounds like a bad Q-Box. I would get an estimate from a Sony authorized servicer as this part may be quite expensive. On the 55A10 model this may be the B-Block and is also quite expensive. Getting an on-sit estimate would be the first step I suggest. Again go with an authorized Sony servicer. Call Sony or go to Sony.com for customer service. Good Luck
