Question about Sony KP-51HW40 51" Rear Projection Television

Sony KP-51HW40 51 - TV failure

My tv is turning off after about 1 minute of being on and then proceeds to flash the red indicator 8 times when it shuts down.

Any idea what this is? I think one of the boards may be shorted.

Let me know if you have any idea. Thanks in advance!

    Are you sure that is all that is broken? The TV probably isn't worth much more than 200 these days.....

    Is that part easy to replace?

    do you know if this piece has also been effecting my tv with the green lines and other flickering?

    Yes eight blinks is the error code for a defective flyback, yes they are very easy to change takes about 45 miinutes to take out the old one and put in the new one. the link I posted has free online tech support available by instant message for their customers in case they need help doing the repair.

    thats a very strong possibility as the flyback is what powers up the heaters in the picture tubes so it could definately cause the tubes to flicker before it died completely.

Sony bravia shuts off

A short circuit with its main board component, can make 8 blinks of standby/power light. These blinks [flashes] are fault indication. You can get an idea about the faulty stage circuit inside the TV, by the number of these blinks. Count it carefully, by switching it ON and OFF, more than 2 times at least, so that, you can make sure about the number of these blinks. If you wish to get more details, check the site linked here. Surf the site in "MOSAIC" view.

Mitsubishi projection tv picture and sound turn off but the power button remains on with no picture or sound turn tv off real quick and then back on and works for 2 mins then turns off again what could be...

Here's the basic troubleshooting:

  1. Make sure that no front panel buttons are inadvertently stuck in an "engaged" position.
  2. Disconnect ALL devices from the TV.
  3. Press the SYSTEM RESET button and hold for 10 seconds. Proceed if the problem still exist.
  4. Press and hold POWER and MENU buttons simultaneously for 20 seconds. Proceed if the problem still exist.
  5. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours.
  6. If it still shuts down, press the DEVICE and MENU buttons on the front panel simultaneously and hold it for 5 seconds to activate the Error Code Operational Check. The status LED indicator will then flash denoting a two digit code.
  7. Count the number of flashes then pauses for about a half second then flashes again. The first number of flashes indicates the first digit of the error code and the second number of flashes indicates the second digit of the code. For example, if the error code is "35", the LED will flash 3 times, pauses, then flashes 5 times. The error code is repeated a total of 5 times.
Please let me know the code you got and I'll tell where the problem lies and how to fix it.

Won't turn on.. Operation indicator is red, Lamp indicator is flashing red??

According to the E44W48LCD service manual, the temperature indicator red light states the projection TV shut down due to overheating. Red (flashing) states the projection TV shut down, check the cooling fan.
