Recently replaced my Mitsubishi hc4000 bulb after it blew. Now none of the LED lights come on at all. Not even the red power light.

SOURCE: brake light bulb Mitsubishi Eclipse Cars

look for access panels in rear hatch there will be one on each side remove those and there will be 10 ml nuts holding the light housings on remove those then you can access the lights

SOURCE: I have a Mitsubishi WDC657 with a bulb that blew

I have the same tv (mitsubishi WD-C657 from Costco) with the same problem. (When turned off the lamp light is red, and when powered on the screen stays black but I hear white noise) Before I order a new lamp I want to make sure that this is the correct fix. If anyone knows the correct fix please email it to me at [email protected] =)

More likely a faulty ballast. Check connections.

SOURCE: The range-top light blew and now replacement bulbs

My Whirlpool/Roper microwave/hood combo has the same problem. I replaced the bulb twice, checked the bulb and it works, but not in the microwave. I wrote to Whirlpool asking about the problem. Haven't heard from them yet.
