Question about Sony KP-57WS520 57" Rear Projection HDTV-Ready Television

2 Answers

No Power-blinks 9 times

I've seen many of the same solutions to this problem, but do I dare take out the G board myself? Will it screw anything else up. You can't get a new G board anymore. Where do you get the diodes and how do you replace them yourself.

Diodes can be repaired through fault finding. You will need to locate test points on the board to identify the faulty diode if indeed it is this.

My sony the standby button blinks 11 times then 5 times then 5 times. Would the problem be the same as those that have it blink 9 or 10 times?


if the set blinks 9 times its the G board which is the board on the far left side where the power cord plugs into. The D board is the large board in the center just to the right of the G board.

No power


Check the ribbon cable connections between the boards to insure they are correctly seated as a 19 code usually means
Chassis detection, which means its not detecting a valid chassis usally the ribbon connections are the cause of that.

Toshiba 65H81 blank screen and red blinking light....help


I don't think is any lamps.
If you are handy try to open the back of your tv, (unplug it first) don't touch anything just yet, you need to make sure you discharge any static left on the power board (the first from your left )Unplug power cord from the board. Take a heavy long screwdriver (Isolated) and lightly, touch a few parts on the board including the thick red wires that go to the lamps. Once that's done its time to put your dexterity at work. You need to lift that board (PD 0074) so that you can check some fuses like F850, F852, etc. for continuity. Mine were out. I had replaced those two and I had tv for another year. Remove the screws that hold the board. Now, this board PD0074 is connected to the next board by two white connectors and one blue. ....lift them up from one side with your finger nail. Don't unplug anything from the power board, just loose some wires so that you can lift the whole board on one edge. Get a voltmeter and set it to check continuity. Mine has a buzz. Look for them fuses if they are bad , ....replace them. (You can buy them at Partstore.com.....punch in "fuses"or "125V 2A")
In my case that was the only problem a year ago. Now I also have the same problem but this trick didn't work for me anymore. The Power Co,. messed me up big this time. In fact the problem with these Toshiba rear proj. is that when the power in your house goes out and comes back right a way in a split second and you don't have a power regulator, guess what : 'red led blinking'
In my case this time the whole power went on and off a few times within 10 sec. and by the time I got to the TV to unplug, it was to late. I think I have to replace the whole PD0074 board....and that's expensive.
Good luck
