Replace Both of your STKs convergence ICs they are big black ics they will have STK numbers on them STK392-560 ect. Parts you can order on line www.electronix.com or call 1-800-223-3205 you also need silicon heat sink white compound to put on back of new ICs. Use same # on stks but if they are 110s use 180s if 020s use040s.

I have a sony KP-51HW40 and when i turn it on about 5 minutes later it shuts it off.


If the TV works fine during the 5 minutes its on then your power supply in the tv is heating up and shutting off. If you have some mechanical knowledge you can buy another power supply from Ebay for around 35.00 and replace it. will require some soldering

Sony KP-511HW40 fleshing with green color and shuts off


this is a common fault adjust the little black box in front behind the small wooden cover. you will see 6 controls don't adjust any of the top 3 only the bottom knobs 1 for each color. slowly back the control counterclockwise turn the set on and wait untill it shows a picture, slowly adjust the control for the color in question utill the color balance is correct- black and white with the color setting turned down all the way with the user menu when balance is ok you are all set.. turn the color back up with user control. rtepeat process if needed.

KP-51HW40 Sony 51" Fades to blue screen


The service manual on page 8 shows how to adjust the Red/Blue/Green screen voltages. To get to the adjustment board, take the front speaker grill off (two screws at the bottom left and right) and set it aside. No need to disconnect any wires. Then remove the plywood board with 4 screws that exposes the screen/focus adjustments. The top 3 adjustments are for focus, and you need not mess with these. The bottom 3 adjustments are for Red/Blue/Green screen voltage rough adjustments. My screen showed red lines, so I had to turn the bottom right adjustment with a philips head screwdriver just slightly until the red gun retrace lines where no longer visible.

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.
