What is the lamp indicator light and where does it blink

Are you sure you installed the lamp properly and put the door back so the interlock switch is functioning. Sometimes installing the lamp will get slightly displaced and is not plugged up properly and will indicate a lamp blinking light.

The standby light blinks to indicate problems with the TV. Six blinks indicates an internal problem, I suspect with the lamp. I recommend contacting a Sony repair shop to vacuum out the TV and replace the lamp. Installing it yourself has no bulb warranty and you cannot vacuum it out without taking it apart. Lamps are $250+ each...

The blinking lamp light refers to the lamp door not being closed. There is a little lever behind the main panel and if that's not shut, the lever won't be pressed in and therefore the light blinks. If it's a failed lamp, the lamp indicator light will be a solid, not blinking.

i had the same problem, it should be the speed sensor on your transmisson after a while your speedometer will stop working. no clue on the lamp...

Replace the bulb.

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)

Lamp is bad need new lamp

Having similar issue with my PT-44LCX65. Lamp blew and replaced it (last month), never figured out how to reset timer. Now red indicator light blinks once every 5 seconds and after about 4 minutes TV goes black.... Any ideas?

Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...

maybe you have lost contact at the lamp circuit! check the CRT circuit and the lamp circuit!
