LED flashes of 8 times are indicative of a "High Voltage Error" which means something along the lines of "T8005 is faulty. (D board)" according to the service manual. Most likely it will need a professional to look at it. A link to the service manual is here: http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html

Yes you have bad green and red crt but with an adjustment you can still use it. remove the front panel and you'll see the focus pack (it;s a black piece with 6 rotating knobs on it. Adjust clock otherwise the red and green screen (the bottom line knobs) till the lines has gone. The better way to check it is to adujt in video input with no signal, just black screen.

SOURCE: troubleshoot-5 blinks red light front of TV

TURN TIMER OFF. GO TO SONY.COM, TROUBLESHOOTING, OR The STANDBY light is flashing on the television and there is no picture or sound. Solution
sp.gif sp.gif The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.

  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.

My KP-51HW40 clicks off after running for a period. The red power light blinks when it goes off but screen stays dark. When TV is shut off for a while it restarts and runs fine. The "On"...


Hi,
KP-51HW40 shuts off due to incorrect white balance and blue arch lines is an evidence of that incorrect white balance. I hope tv standby red light would flashing 5 times then 3 seconds pause and again 5 times when tv shuts down.
This is rear projection tv that has three picture tubes (red-green-blue) inside to generate picture that projected at front screen. These three picture tubes must be drive with correct drive voltage to produce good picture of each color.
Solution for your tv problem is Screen Voltage adjustment that can be done easily if you are handy with electronics stuff repair.
Let me know your expertise level to guide you more and if you feel unconformable by tv repair then local tv repairman will help you to adjust white balance in tv.
Hope these info will help you.
Let me know if you have additional questions.
Thanks.

Sony KP-53HS10 rear proj TV - picture goes on & off


If the adjustment of the screen settings does not fix your problem, its likely that one or more of the CRTs (picture tubes) is defective.

And, the CRTs for these sets are hard to find and expensive.

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.
