Question about Sony Grand WEGA KF50WE610 50" Rear Projection HDTV-Ready Television

1 Answer

Need verification of potential ballast issue and to be directed to step by step fix it directions

I have a Sony Grand WEGA KF50WE610 made in 2003. I just replaced the lamp in front and the TV worked well for 4 days then last night when I turned the power off the TV showed a solid red light in the on/off indicator but the TV screen remained on with no picture displayed. I thought that it would eventually shut off, but it never did. Several hour later when I discovered it was still on, and I tried to turn it on it would flash green, yellow then 3 red flashes, again and again until eventually clicking and the on/off light would stay solid red for awhile then I'd hear a couple more clicks from the t v like when it shuts off. I believe this is a ballast issue, but have no Idea how to replace it. Can you confirm if this sounds like a ballast issue to you? If so can you direct me to step by step directions on how to replace it, and where to buy a new ballast. Much appreciated, David

My kds-r60xbr1 sony wega projection tv is blinking green then red and wont go on how do i fix this problem .i also just replaced the bulb about 3 months ago.


Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

It overheats and pops the Xl-2100u lamp?


by pops? do you mean it explode? how many lamps? it could be the fan that supposed to be ventilating the lamp or it could be the the ballast, why the ballast because the ballast regulates the voltage in order the keep the lamp on, for ignition it sends around 15,000 volts after that it regulates the votage to a small amount of voltage around 5,000 so it could be sending the big amount of voltage all the time never regulates that or it could be regulating and then sending another big amount of voltage over and over until the lamp doesnt handle those changes.

Check ballast supply board that drives lamp and is attached directly with lamp, ballast supply board can cause of this problem, would be cause of smoke while tv shows picture for moment.

Sony wega won't turn on


It sounds like it is the ballast. The ballast is what fires the lamp, if it is faulty, it will continue to blow out the lamp. The fan cooling could also be the issue but the TV will usually turn itself off if the fans are not spinning at the right speed.

Red light flashes 3 times


It's either a lamp issue or a ballast issue. Lamps are cheaper then they used to be so I'd try that route first. A ballast replacement will require a repair center.

Shutting off and on.


It seems it could be a ballast issue. It might not have enough energy anymore to keep the lamp on.

My Grand Wega KF60WE610 has no picture and has a buzzing sound when turned on. If left on the green light blinks and the buzzing sound may or may not occur again. Can anyone diagnose this issue?


That buzzing sound is this kind of Tv LCD Projection, is most likely a issue with the ballast (only if sound cames near the lamp) you can check that just follow the cables that are connected to the lamp, take out the back cover of tv, and keep pushing the switch cover (if not tv will not turn ON). and check if that sound comes from the only board connected to lamp. if it does, you are going to need a ballast very soon.

Has your TV been sent in for the original factory recall? I had the issue a few years ago, it was covered by Sony due to the factory defect.
