Question about Sony KP-65WS500 65" Rear Projection Television

1 Answer

5 blinks, Sony KP-65WS500 stays up only with one CRT gun at a time....

The TV turns off itself immediately after power on. the standby led blinks intermittently 5 times each 30 s. I opened the front and plugged the CRT guns one at a time (CG, CB or CR boards). Surprisingly, when powered on the TV stays up and doesn't anymore turn off itself. Could you help me locate the culprit circuit, please! Thanks!

    As the TV power on only with 1 CRT gun at a time, I tried to increase the screen volt with a small screw until the lines disappeared. I did with the blue, the green and the red CRT guns but once I plug them all, the TV can't stay up.Thanks!

    I turn all 3 screen volts pots down to mini and then tweak them to 1/8 turns. But still the TV, shuts off itself and the standby button blinks 5 times. When I turn down those 3 pots below that 1/8 turns, the TV turns off itself but instead the standby led blinks 8 times. Thanks!

    Thanks!

    Yes, my TV is doing the same thing. Red and green are working great. Blue seems to be over powered. Screen is completely blue, i can hear audio. I also have the voltage all the way down on the blue and it is still WAY too bright, cant see any picture. What can I do? Please help.

5 times blinks shows White Balance error in tv. You need to adjust Screen Volts (G2) and problem will resolve. Screen volts controls located at Focus Block as shown in below picture.

Standby light stays on and the tv will not go on


Please check batteries in remote that seems not working. Sony TV would either turns On or standby light will blinks if TV gets any internal problem.
You question shows standby light stays On that means TV does not receive power on command from remote.
If standby light is blinking in sequence, let me know how many times it is blinking and also intimate exact model number of TV to find out possible solution.
Thanks.

Sony KP65WS500 5 blinks


I think problem is in Protection circuit itself. Protection seems unstable in your tv that's why it doesn't give you chance to diagnose problem.
Try to isolate protection command and check tv.
Its an idea and hopefully it will work.

Check your CRT boards on the end of the tubes for burn spots, and burnt components, check the resistors to make sure they are not shorted, burnt, and they read the correct resistance. Check the diodes to make sure they conduct in one direction only and are not shorted or open.

I am getting 5 blinks


If the whole screen turns a bright blue and shuts down then you may have a bad blue crt. This will need to be replaced plus adjustments/alignments. Get an authorized Sony servicer to do the repair. Good Luck
