Re: Sony Grand Wega kf50we610

Hello Kpollman,

Since this is an LCD projection television I would check to see if there is an image on the LCD screen. if there is not I would check the circuitry connected to the LCD. Now if there is an image on the LCD screen I would make sure that the white light bulb is working. Now this might seem backwards, but I have seen folks replace a blown bulb only to find out that the LCD screen was gone also, so this little bit of reverse angle troubleshooting will at least help you solve a major problem first and then allow you to move on to the simpler problem of a blown bulb.

I hope this helps,
Thank you,

Sony Grand WEGA KF50WE610 tv will not turn off

Problems that do not happen all the time are hard to find--2 things: if set blinks the red light try to count the blinks--usually that is an error code.

Also this set if it does for the most part work should have an error buffer.

With the set turned off and using the Sony remote:



Volume down


If it has this when it comes on there will be a box in the middle of the screen with several items listed---all must have a zero to the right of them---if one has a number(any number) it means it has detected that error that number of times.

Let me know what you find

Sony Grand Wega KF50WE610. No picture, no sound. Green light comes on and then starts flashing red. Bulb light does not come on.

5 blinks is lamp driver error, but is usually the lamp. Else it's the lamp driver (ballast), if it has the ~280VDC coming to it.
