The Lamp Ballast p/n 6316000009B could be bad if you already swapped out the lamp with a known good one as you can't tell by looking at them if they're bad. It may be worthwhile to have a technican look at this set as it would be an expensive mistake if the ballast is not bad.

Green light blinking, tv won't turn on


Lamp lifetime is not 100% predictable. A lamp may fail without notice, although this is not usually the case. The picture is more likely to become noticeably dimmer as the lamp nears the end of its lifetime.

While there is nothing wrong with using a lamp until it fails, some customers may want to purchase a new lamp and replace the existing one when they notice that it is aging.

If the lamp fails in a Mitsubishi MicroDisplay TV, there will be no picture on the screen and a red front panel LED indicator will illuminate.

Tv light standby red just keeps blinking after replacing bulb


Hi,
If red light was not blinking before lamp replacement and after that it start blinking 3 times then pause for three seconds and again blink, check lamp cover that has not been fixed on tv or it is not fixed/ seated correctly there.
Lamp cover is first thing that you removed from tv to replace lamp.
Hope these info will help. If red light is blinking other than 3 times, let me know how many times it is blinking along with tv model number written at rear to provide you helpful info.
Thanks.

Lamp or power?


Thats a lamp switch error. You need to keep trying to reseat the lamp till it goes away.

Power light keeps blinking Red and TV will not turn on


Is the light blinking constantly or is there a long pause then more blinking. If constant check the lamp door switch . Usually it is broken or jammed. If you jumper it and the set comes on that it. 4 blinks is bad fan.
