How do you know that the bulb is working or when it is burned out and requires replacement? Mine is on, but can't see any light to check.

Measure the power consumption with something such as Kill-a-watt. Indeed a better design should've left a visible window.

I tried that also but the true test is when it got dark and the light did come on and wentoff in the morning. My bulb did stop working however after a few weeks so I used the return service at Amazon. They replaced it and the new bulb has been working great!

Did you check the fuse? Or see if the original bulbs work still, if not, it's probably the fuse.

Dave, ours did the same thing. We figured it was the lamp going out so we purchased a new one and our problems were solved, its such and easy and inexpensive fix to just buy a new lamp. Hope this helps.

Check your power source. Make sure it's strong enough. Maybe you just got a bad bulb ! Mine is still working fine.

My advice would be to contact the seller or the direct manufacturer. They may be able to replace the damaged bulb free of charge or at least inform you of the proper bulb to purchase and replace yourself. Most companies will provide missing instructions/manuals if you call and request them or find them online

try pulling it back out and check the bulb. remember do no touch the glass. reinstall and secure the screws.

Make sure your bulb is not lose, in the socket, if you still have trouble, try putting the bulb in a lamp or something, to see if it does the same thing, if it does, call the place where you got it. thank you

Hmmm, good question. I haven't had to replace the bulb. So, I don't really know.

It may be burnt out, should come on when unit is running will have a blue glow.

Might be from dust that is getting burnt from the heat of the new bulb. Try some compressed air to blow the dust out.

My guess would be the bulb is bad.It's easy to replace but you may want to call a local tv repair place if you don't feel comfortable doing it yourself

Not wanting to look directly into it, I used a mirror from the side to check . All my lights were on, more than ten. I would call the company to see what they say. I've used mine successfully so far. Good luck.

Try to adjust the bulb, if this doesn't work, it's probably a damaged bulb.

Okay, I've been asked to review this item several times... and this is the first I've heard of this. I'm pretty sure, mine warmed up right away. It sounds like you need to check to see if the light bulb is screwed in all the way so it's making a connection. If not, I would exchange the light bulb... keep the other light bulb until you make sure if the replacement light bulb does the same thing because it could be the lamp itself.

mine stopped working a few months after I bought it. We bought a new bulb online but still didnt work.
