    When I power the unit on the standby light flashes green, the fan turns on and after about a minute the standby light turns orange and teh lamp light flashes red. This unit has done this with the current bulb and a brand new bulb.

    I have had the exact same problem. I replaced the bulb, I get a green flasher for 1- 2 minutes, then is shuts down and the red "LAMP" indicator comes on.

    Same problem with a Panasonic PT-LB10NTU properly replace the bulb with a new (very expensive) bulb and the green light and fan comes on for a minute or so then then the red light starts flashing.

    I have the same problem with the PT-LB10VE version, tried two projectors and a new replacement bulb

    Bought my PT-LB10VU brand new in early 2005 and used it once. It sat in a cabinet until February 2009. We'd forgotten we had it, actually. But when we fired it up, it flashes green, then to steady green but no light, then repeats flashing green, then lamp indicator flashes red! Thinking maybe the bulb (with less than 10 hours on the machine) might have been jostled or something, we bought a very expensive replacement. Same problem. Hasn't anybody figured this out yet? How could power supply or ballast go bad with so few hours on the machine?

    OK...can anyone tell me how I can test a thermosensor? The repair manual has taken me to this step, but I'm stumped at this point.

It seems there could be a number of problems causing this. For the PT-LB10 series, there's a service manual at

Replaced bulb for a PT-50LC14...worked great til I turned TV on then click off 25 seconds after. 3 hrs later...turned it on and nothing except 8 green blinks on power button then solid red(shuts off) No...


Remove lamp to see if it was not inserted correctly (easy mistake to make) and also make sure door on lamp was closed securely--a safety lever there will prevent set from working if door not engaging the lever.

impossible to actually see if lever is Fully engaged---with door off try to engage with a match stick or something not metal--see if set comes on that way.

Red/green lights both blink and tv will on turn on


Are the red and green lights blinking at the same rate or not? If the green light is blinking every 3 seconds and the red light is blinking every 1/2 second, the lamp door is not properly secured. If both lights are blinking at 1 second intervals, try replacing the lamp. If a new lamp doesn't solve the problem, the TV needs service.

I hope this helps.

I HAVE A SONY KDS-60A2000 WONT TURN ON. RED LIGHT BLINKS THREE TIMES. TRIED NEW BULB. NO DIFFERENCE


Hi,
3 times red light blinking indicates that Lamp Cover has not been fixed in its location properly after lamp replacement.
Please make sure lamp cover (its first thing that was removed to replace lamp) is installed securely.
Thanks.

Just replaced bulb and the tv still does not work? the green light flashes 9 times and the red light is solid


Howdy;
Double check the Lamp installtion. 2) make sure the Lamp DOOR is properly closed. 3) unpug TV from a/c outlet for about 5 minutes. pug back into a/c source.

Are you sure the green light is blinking and not the red light?

Good Luck, Big Irish.
