Sorry friend, but the only sure thing is that you're getting a lamp driver error. Odds are you're either having an issue with the ballast or your power supply can't supply the voltage needed. If you're good with electronics you can check the voltages on the power supply and try to rule that out. Otherwise you should take the set in for repair. Good luck.

Tv will not turn on

For dark picture I need to ask one question, How long ago you replaced its lamp? one year, two years?

Picture brightness is depends on lamp in LCD rear projection (DLP) TVs and if lamp got weak in generating light, you will see dark picture.

I would recommend to replace lamp and buy Sony original lamp from Sony Accessories Store.

Required lamp part number is as follows..
F93087500 LAMP BLOCK ASSY XL-2400
and price is $200
Good luck.

hello, if your still getting the lamp error then your lamp cover is'nt on right i'ld suggest taking cover off then re-installing it if the t.v. is'nt reading the lamp cover then it'll give you this error after re-placing the lamp, also take the lamp out and re-connect make sure the 2 prongs are on the lamp tight.

Ac not working right

You will need to add some coolant. Most auto parts stores and hardware stores have recharge kits. Purchase a kit with a gauge to prevent overfilling.
