Sony KP-65WS500: Shuts off when hot?

Hello friends,

I am having an issue with my ancient Sony projection tv. It turns on fine but will shut off when the TV heats up from a few minutes of watch. I had a similar problem with a Toshiba which was solved by replacing the bulb. I was wondering if the same remedy can be applied here. Please let me know if you know of any bulb replacement place online for me to purchase from, part number, and or perhaps another alternative as to how to resolve this issue.

There is no "bulb" in your tv , you have a CRT projection tv, need to have power supply checked as well as the convergence board. Have a trained tech do it, this is not for beginners. Julio

Tv comes on then turns itself off

Sounds like the projection bulb is heating up then it shuts off for safety reasons. If you can locate the bulb, there is most likely a screen (wire mesh) that traps dust when the fan is on to cool the bulb. Try cleaning this screen and see if it helps. It could be already too late and you might have to replace the bulb.

Sony KP-65WS500 TV shuts off by it self....after I turn it back on, a minute later it goes off again.

The 8 blinks means its a High Voltage error which mean ur D- board is bad it'll be T8005.

My sony KP-65WS500 turns on to blue screen then black with only sound, then shuts off? They just replaced are cable box a few days ago. We unhooked everything and tried to play a dvd....same thing happens?...

It seems that you have an issue with your Video Board, but you say that when the screen turns black, it shuts off. The lamp is not going to be the issue here, since it only produces a white light, regarding the image cutting off, it could be the ballast, but before this, you should've notice a dimmer image. For what most probably the power supply might be having a glitch. Definitely I recommend to contact a Tech so they can analyze the symptoms on the TV and diagnose the issue.

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
