Hi, i had the same problem today. i took a risk and opened the front bottom panel(regular star faced screws located at the side) where the speakers and buttons are located. then i unscrewed the panel located right below it. i then unplugged the wires that were connected to the bulbs(sorry i dont know the technical term for it but there should to be blue,red,and green bulbs). when i reconnected i turned it on it was fine. its been about six hours now and it's working perfect. hope this helps.

    sorry i forgot to mention before, i took off the power supply before i performed all the above mentioned steps. also, when i disconnected the bulbs, i left the wires off for about an hour.

I have a new smart blue ray player and am trying to set it up using a hdmi cable to my sony KP-46WT510 tv and I have video but no sound?


Two things come to mind. !. are your cables plugged in right? Yellow->yellow, red->red, white->white? 2. Is the sound on the TV itself turned up?

What's your problem?Hi, I have a Sony projection TV KP-46WT510 theres no picture or sound, but it still turns on and I can see the the on screen menu. When I turn it on the led blinks four times


You can Google and find the service manual which will explain what the 4 blinks means.

If you have the Sony remote with the set off:

Display, 5, Volume down, Power

If the set has it you will see a box appear on screen with a list of items--all should have a zero to the right of each---one with a number indicates the number of times that error has been detected.

Let me know if you have questions or cannot find what the four means and I will research it.

Picture went out and red light on the front by power button is blinking. When I turn TV on I can hear sound but no picture,, then TV turns off automatically after a few seconds.


Hi,
It seems problem with low screen voltage to three picture tubes in this rear projection tv.
If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue.
Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you.
Thanks.

No picture or sound


3 times error shows that lamp is not installed properly or lamp cover is off / not fixed.

If you replaced TV lamp recently then check lamp cover and make sure to seat it properly.
Need further info, let me know.

6 bliks on sony kp-46wt510


KP46WT510 Shutdown 6 Blinks. 6 Blinks = Low B+ OCP/OVP
SOLUTION: Replaced Flyback transformer. It had no rings on the ringer test.
HQ
Comments: Any load on the B+ line can cause 6 Blinks.
Example: If the 200v line is loaded down will cause a drop in B+ due to bright picture current demand.
