i now have a blue lite and the amber led is flashing once every second. if i push the power button, then i see (2) green leds
Expert:  Anthony_Infotech replied 6 months ago.

The green LED s may indicate the set is ON if you press the MENU button of the sets own remote does the menu come up?

The blue and amber means the lamp is waiting to be lit

Customer: replied 6 months ago.
tried pushing the menu .now i have a solid amber led and 2 flashed red leds.
Expert:  Anthony_Infotech replied 6 months ago.

Expert:  Anthony_Infotech replied 6 months ago.

And the price also important?

Customer: replied 6 months ago.
$60
Expert:  Anthony_Infotech replied 6 months ago.

The 3 blinking yellow is the main-board is not booting however it could be locked up because of all the trouble with not lighting the lamp so when you rebooted the set that should have unlocked it, the thing is the fault is still there and its the lamp not lighting, you have replaced the lamp and ballast (a complete thorough job) however you have fitted a copy lamp and these lamps are simply no good we have endless trouble with them either behaving like this from the go OR failing weeks or months down the line, you need to fit an OEM original lamp and you can get one of those from www.dlplampsource.com <<click, they only sell original manuf lamps.

i put my original lamp back in. same problem,its only a year old
Expert:  Anthony_Infotech replied 6 months ago.

When you say same problem do you mean 3 blinking yellow?what do you get with the original lamp

Customer: replied 6 months ago.
I put the oem lamp back in.your previous info was wrong.green leds is standby.blue is power on.i was turning tv off based on ur info. it's now working like it should but most likely it will not turn back on every time.which is why I bought the new parts.i assume my lamp is good because it's working right now? Have you seen intermittent lamps?
Expert:  Anthony_Infotech replied 6 months ago.

Yes your right on blue, standby is not even in the service data,yes a lamp can be intermittent but if the lamp fails intermittently you get yellow solid red blinking however it is also possible to get blue ON yellow blinking for intermittency so yes as I say we only use genuine OEM lamps copies are no use in this

Customer: replied 6 months ago.
Thanks but you have not solved my problem. I don't want to buy another lamp and have the same intermittent problem.i was hoping for an answer that will fix the issue.
Customer: replied 6 months ago.
Also I never heard an arcing noise like the ballast was trying to power a bad bulb.
Expert:  Anthony_Infotech replied 6 months ago.

Its not possible to move on until you fit a genuine lamp in that set that is the way it is sorry its not what you want to hear but I nor anyone else can change that fact , solving problems boils down to taking measures to do that again that is the way it is

Expert:  Anthony_Infotech replied 6 months ago.

If you have a ballast issue the lights will tell me I have dismissed that because you said you replaced it?

Customer: replied 6 months ago.
It was flashing amber 3 times this morning. It will still do it sometimes. But right now it's working .how does it flash if the bulk is bad? If the ballast is bad?
Expert:  Anthony_Infotech replied 6 months ago.

OK let me explain that 3 yellow blink code that means BEFORE the set even thinks about lighting the lamp that the set is not booting up, rather like a laptop wont boot up sometimes, that is what that 3 blinks means so its not even getting into a position were it knows its ON (blue light) so it could have a main-board issue however it could also be caused by confusion on the main-board because of the problems you are having with the light engine (lamp\ballast) now you said you replaced the ballast so I have dismissed this, that is a board in the set that fires the lamp
