Flashing and Rolling Picture Problem on SONY KF-50we610

5 year old TV with flashing and rolling picture problem. The flashing looks like it is oscillating at about 3 flashes per second and the picture is rolling up. There is also no sound coming from the set. I checked other sources and the flashing is an all inputs.

I am guessing that it is a mainboard failure. Can anyone verify that and if so, what will be the cost of repair?

SOURCE: TV Picture Goes Black

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions

SOURCE: kf-42610 blue hue and blue dots on screen

Hi Guys

The Blue dots or discolouration you are seeing is due too the Blue LCD screen having cracked from excessive heat. This normally happens when you have a power failure while the Television was on. This obviously because the Blue LCD sits next to the lamp - the main cause of heat. The correct part number on the 60" is A-1086-952-A. It is very, very ,expensive.

Sorry to have been the bearer of bad news. Good luck : )

Clean the cooling fans, specifically the lamp cooling fan located inside the rear cover, above the optical blocker. This is easily blocked with dust and causes overheating of lamps/shortened life.

SOURCE: how do i replace the lamp on the kf 50we610

Sorry, they misinformed you!

On this model Sony the lamp access is located to the side of the set. You will see a small hook you can push down with you finger releasing the lamp outer cover. There might also be 1 screw to remove the panel.

Now you will see the lamp inner cover. It has a grey handle in the middle of it - to dark to see down there, get a flash light. Remove this by turning it counter clock wise. Now pull the cover out. Note the chip on the one corner of the cover. It can only fit back the same way.

Now you will find a slot you can fit your finger into. Pull this down and pull the old globe out.

FYI - If the globe has burnt leaving a white discharge behind inside the globe - great, your TV is healthy. If it blew with a black discharge I would suggest you take a hear dryer on cold setting and blown as much dirt from inside the globe cavity as possible. also try not to switch your TV on and off to often. If you leave the room and you know you will be back within a hour, leave the set on. You will much easier reach 8000 hours of globe life. 8000 Hours is possible, I have seen it before.

Now place the new globe into the socket. Just push it in until you feel the locking mechanism engage. Return the inner lamp cover. Turn the grey lever clockwise.

Now all that is left is to clip the outside cover into place. Put the screw back if there was one.

If you have to remove more than 1 screw - you have gone too far.

P.S There are certain lamps that does not have a clip, but rather a HEX key screw. You will receive this hex key if you bought a genuine Sony globe in the box.

Good luck.
