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.

Re-insering the flyback wire is usually very easy. Push in and give a slght turn and check to see if grabbed. It sounds as if there is more issues than flyback wire. TV should turn on without one crt connected

The standby/timer is flashing 6 times on my Sony KP-53HS30 TV


no the 6 blinks indicates a missing voltage. If your talking about a sony lcd KD or KE model you probably have a bad thermal fuse. You must also clean or change the Lamp fan so it won't blow again.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

ITS PROBABLY THE RED PICTURE TUB (CRT). IT LOOKS EASY TO INSTALL, BUT YOU NEED TO MAKE ADJUSTMENTS TO THE SCREEN ONCE IT IS INSTALLED. THE PART IS $3OO. TRY TO FIND SOMEONE TO INSTALL IT FOR $150 OR LESS. HERE IS A WEBSITE TO HELP YOU MAKE ADJUSTMENT IN THE FUTURE ON YOU OWN.
