Are you sure you didn't turn the knob too far down? Just a though. I don't know off hand which one is the D board but the boards are marked. Please be careful when working on TV sets as they produce high voltage which may reside even while the sets is unplugged. Also I would do more research on this problem before purchasing a new D board. I have been told that the picture tubes in these sets go bad. G what a bummer guess what set I own :( Here is the code for 8 blinks, it looks like you may just have to replace a part on the D board.

8 times, Diagnosis: High voltage error. Possible cause: T8005 is faulty. (D board)

I hope this helps, keep in mind its hard to diagnose issues without actually being there.

There are three fans the one that usually fails is located on top of the optical block and cannot be reached by the owner unless you take the set apart yourself. What is happening is that one of the fans are not spinning fast enough or has stopped altogether. The best solution is to replace all three fans cleaning may not be enough to get a slow fan up to speed, and the tech should blow out the dust in the duct work. This is what the tech coming out will (or should) be doing. Also some fans will have an intermittent startup, and cause this intermittently, so it is a good idea just to replace the fans instead of just cleaning them.

I had the same problem in blue. I took the right front speaker cover off (pops off) and the access panel on the right side 2 - 4 screws. In the upper right corner is a black plastic box with 2 rows of 3 adjustment screws. All I did was turn one of the "screen" screws (not the "focus" screws). Hope this helps. May only be a temporary fix, but good luck...

My Tv started with flashing red/orange colors. Then later the screen turned red/orange and the TV shut off. When I attempt to turn it on again, the screen stayes red for a few minutes then shuts off.


The problem based on the model number is in or around the red picture tube---the bright red screen causes the set to draw too much current and the shutdown circuit detects this and turns set off--self protection.

Each picture tube (3) has a IC chip on the board connected to it--shorted chip or bad picture tube.

Shop repair in most cases.

Sony rear projection kp-577hw40, screen turns red after being on for 10 minutes


This model and some others had bad picture tubes that are no longer available---there is an option here.

If screen gets bright red, green, or blue set will shut down as it detects too much current being drawn.

Seen over 100 with this issue--what can be tried and usually will help is a physical adjustment inside the set.

No parts to replace and takes about 15 minutes to do.

I can tell you how if you want to know.

Screen turns red after 10 minutes


First, lets see exactly what is happening and what is causing it. If your picture starts out fine, and after 10 minutes or so you notice that the picture is getting redder, and the redness slowly gets worse and worse, until finally there is red everywhere with faint curved lines, then chances are your Red Screen control is set just a hair too high. This is a very simply thing to correct. If, on the other hand, the picture is fine for 10 minutes or so and then suddenly flashes very bright red, followed by the set shutting down, then your red picture tube has developed a short in it, usually between the heater and cathode. A good tech might be able to remove the short by arcing. What is your set doing? The KP-51WS500 is one of the newer 16x9 1080i HD sets and the tubes are available from any Sony distributor. When they told you the tubes are not available, that was their way of saying they do not want to bother helping you. The Sony tubes are quite inexpensive, costing about $175, and they come complete with sealed coolant chambers, so replacing a tube is quick and simple.
