Replaced xl-5200 lamp(whole, brand new), not first time. power led blinks green for a while then turns red and blinks 5 times. No picture. tried again making sure everything is snug, same result. Tv model is Sony SXRD KDS-60A2000

3 blinks of Standby/power LED of Sony sets denotes a SMPS board [G-board] failure. . Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

Hello, those sets were bad about the lamp, yes the lamp failing and they didn't break the part number on the lamp is a XL-5200. When I would have calls with this issue, I would say about 75% of the time the lamp fixed it....tks

Hi,
You need to replace Lamp only as existing lamp is weak in result and causing such symptoms.
Ballast supply is fine and working.
Thanks.

3 times blink error code shows Lamp Door is not seated / fixed properly, please recheck it and make sure that door close safety switch is pressed as this switch sends error signal to system control chip.

3 blinks means the lamp cover door is nit properly attached. Remove the lamp door and reinstall it

Hi,
Symptom shows Lamp is weak in result and causing restart of TV again and again. Your TV requires new lamp as per following part number...
A1085447A* LAMP BLOCK ASSY XL-2200U
It is available in Sony Accessories Store for $200 and replacement procedure is written in instruction manual of TV.

Always buy Sony original lamp for TV and avoid aftermarket / cheap lamp for TV safety.

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

i also have the same problem with the flashing green light for a while then a different red light starts blinking on and off around 5 times....and i replaced my burnt bulb with a new one...still no picture.

What are the labels on the lights? Timer/Lamp/Service and what color is wich?
