Green flashes then tv turns off

My Sony, KP-51HW40, flashes green blips and then shuts down. The little red light on the front of the TV goes on and off eight times after the tv shuts down. IS there a part associated with this red flash code or is there something I can do to solve this?

    I could not find T8005 but did find T8002, T8003 and T8004. I did adjust the green color from the front but that did not help. I contacted Sony and they basically said it needs to be serviced. I am going to take it in to be serviced.

    Screen will display a green line then image for about 15 seconds, then turns OFF. The red light will flash 8 times. When this happened was immediately after my 1 yr daugter fell and hit the bottom right portion of the tv. Hasn't worked since! What solutions worked???

    My sony KP51HWHD was working fine until I hooked a dvd/vcr into the front connection panel. The TV then turned green and shut off - same as others reported. If I turn it on it turns green then shuts off and the red button flashes for a while.

    I have sony tv kp-51hw40. I have the same problem as most of us here. My tv shows all blue screen for few seconds then shut off. Stand by light blinks 8 times. I did the adjusting but it didn't work. I openned the back cover of my tv to find out if all my tubes work and I found out that blue and green lights work but not the red. Do you think that might be the cause of all these problems? If tubes/ bulbs need to be replace, can you please help me how to replace it?

  • Dale 9999 May 11, 2010

    Thank you so much for helping me fix my KP-51. I took a chance on your instructions and somehow it worked like magic.

    Question - Why did my TV act up with the blue color and then blink red dot eight times? Second Question is how do I increase the life or avoid certain methods to keep this TV running good?

OMG! My TV has been sitting in a closet for the last three years because I couldn't afford to have it fixed.  I have googled now and then trying to find a cure for its green affliction but never found the right advice until tonight. I can't thank J19666566666 enough!!  I just followed the instructions and presto!  Working TV again! And just in time for the Oscars (which is like the Super Bowl for me).  
The editor in me tweaked the instructions a little...
Its is real easy to fix. There are 2 screws holding the front speaker cover on near the bottom corners (there are plastic plugs covering the screws that need to come out first). Unscrew and remove the speaker cover (pull it out from the bottom a little then sort of down and out to get it loose but be careful because there are wires attached). Next remove the 4 screws holding the particle board panel in place. There will be a cluster of 6 adjustment nobs with a drop of white paint on each one (2 rows of 3 - do not touch the top row). The green is controlled by the bottom middle screw, Using a screwdriver turn it counter clockwise (to the left) ever so slightly (1-3mm) and there you have your TV back. Use the bottom right screw to adjust the red and bottom left screw for blue. 
Thanks again so much!

Its is real easy to fix. There are 2 screws holding the front speaker cover on (there are plugs covering the screws that you take out first).Unscrew and reove speaker cover(you got to give it a bit of a tug to get it off ) then remove the piece of wood cover held by 4 screws .. Once you have taken that off when you look down you will see 6 screw like adjusters with a white painted mark on them (do not touch top row ) the green is controlled by the bottom middle screw ,, witha screwdriver turn it counter clockwise (to the left) ever so slightly (1-3mm)and there you have your TV back .. when the screen turns red use the bottom right screw and blue bottom left screw.. I hope this helps

Solution by J19666566666 clarified again by CrunkMomma corrected this issue for me. This TV was given to me by a friend who was going to throw it out, all it took was a few adjustments as described above (red flash for me versus green) and works like new again. Thanks a ton for the help!

My research indicates a possible faulty T8005. it is locate on the "D" board. t8005 is the flyback transformer. i do not know of a way to test this part other than by replacement. sony part # 1-453-285-21 sony's price about $150.00. you may also have another bad part. sometimes the horizontal o/p can go when the flyback goes. i recomend you call your nearest service center to get their opinon. good luck.

5 flashing light code,unplug CR board,now 8 flashing light code

If you put the "CR" board back on, the error code will once again be 5 blinks. Your problem is likely the TV's IK blanking circuit. The Kine driver ICs on the CRT sockets boards CR, CB, and CG need replacement along with a few components in the 200 volt supply to the circuit.
