Need a lamp for my sony grand wega KFE50A10 - Sony Grand WEGA KFE50A10 50" SDTV LCD Projection TV

Sony KF WE50A1 Replacement Lamp With Housing

After doing a little research it looks like you can get the complete light engine for around $600.00
Time to think about getting a new TV

Lamp cannot be tested like a regular bulb--if set shut down you should have some kind of blinking light up front---lamp possible but not likely as it should trigger the lamp light.

Either guess or call an expert to examine it.

I would say you need to change the lamp, that is what the red lamp light indicates

Sounds like the problem is in your LCD chips.

michaeltong8,

Your problem is with the TFT panels in the optical engine and is an expensive fix. The KF series has a documented problem with the panels but the time to get relief from Sony has passed. Your only option now is to replace the optical engine. I have a tip at http://www.fixya.com/support/r4251975-replace_dlp_light_engine which explains the problem, where to get the parts necessary and how to perform the repair.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.

light engine is faulty. try to clean the 3 LCD flexible wire and its connector on your optic block. sometimes this connectors loosen up.

It is the optical block causing the problem. Sony has had recalls on a lot of the LCD rear projection tv's made over the last 6 to 7 years. The cost of the optical block is around 800.00. Due to the cost, I would check with Sony to see if it qualifies as a recall situation.
I hope this helps,

Look in the set-up menu, or it needs to be done by technician. Read your user manual on lamp replacement.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is XL2400 you can find it here:http://www.discount-merchant.com/Sony-XL-2400-Lamp-F93087500-Bulb-A1129776A-p/sony_xl-2400_f93087500_bare.htm?Click=48173 .Have a blessed one!
