New lamp is placed in tv, but tv won't come on. Light in front of power button is blinking green, then blinks red. Not sure what the problem is

Hi,
Question shows tv is Sony KDF-60WF655.
Green light blinks when tv gets prepare to fire up lamp, check internal circuits then show picture on front screen.
Red light blinking shows some kind of internal problem during circuit check and protection got activated upon some failure.
Count the red light blink as you will see 3 second long pause and post it here to diagnose what section of tv got problem.
Did you replaced its lamp in last 2-3 years?
Thanks.

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.

Its your ballast. it has as short. i recommend changing the ballast. while you are inside the set, i would run a break point test on the power board to be safe but, im sure its the ballast.

It's in standby mode.

Do a reset and see what happens

While holding down the reset button on the remote
Press the power button on the tv
(The tv will turn itself off the back on)
Now release the reset button

It sounds like the lamp needs replaced.


Please rate this a fixya

if the lamp light is flashing u need to replace the lamp. u should have instructions on the set or in the manual

Check the lamp door assembly, if the lights are alternating red then green, then this might mean that the metal pin that looks like a roofing nail is not making contact with the metal clip. Remove screws, reset panel in place and turn on, the red power button should be the only light on.
Good Luck!!!

Your service manual on page 82 steps you through decoding the blinking
1) there are two lights on the front near the reciever of the remote signals (Temp indicator and Lamp Indicator)
2) If the Temp indicator is on then they recommend you contact a service center
3) If the Lamp indicator is on and the power light stays on (no blinking) then you need to replace the lamp. Otherwise it says to contact the service center.
4) Counting blinks with the lamp indicator (1 every 5sec - lamp will not light or is abnormal, 2 every 5sec - lamp voltage is abnormal, 3 every 5sec - lamp temp is too high, 4 every 5sec - other error)

there are fans inside tv need to make sure they are clean and free of dust

I think this sounds like my problem (need to replace the projector lamp). However, when I hit the "on" button, my SXRD 50" blinks green for about a minute then starts blinking red. Can you confirm the bulb solution? I was very pleased with this sight when my fan malfunctioned. I got the fan in a matter of day's from Sony and it fixed that problem.

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