Question about Runco CL-510LT Multimedia Projector

Open Question

Unit will not Turn the lamp on. It powers up and you can hear the fans blowing you can also hear the clicking noise of the lamp trying to be started. It will do this about three times. Then I get a red blinking light with a constant green light lit. The fans continue to blow for about 3-4 minutes then the unit shuts down. I opened the front cover and removed the bulb.It doe's not appear blown.I also cleaned all the dust out of the unit. There was no visable signs leading up to this action. I was watching tv one night everything looked perfect then the next morning I went to turn on the unit and it would not work. Any suggestions

SOURCE: unit not powering up. New lamp installed but

a couple of things did you reset the lamp timer? Sometimes if the panel door lamp is open or not closed you will not be able to power up. Have you tried removing the lamp and reseating it? Perhaps the fuse is blown...you will need to remove the cover and look to see. fuse should be located in the area of where you plug the power cord again you will need to remove the power cord.

SOURCE: On my runco vx101c ,

Hi.

It sounds to me like the new bulb that you've purchased is just as bad as the old one that you took out.

If this was a regular flat screen tv, instead of a projector, then I would say that it was a cpapcitor problem.

But you said that the problem didn't come around UNTIL you replaced the bulb.

I wonder, does the bulb have a special way that it needs to be seated in it's plug?

It could be that it can only go in one direction in order for the contacts to work properly.

Now, it could be that, in removing the old bulb and replacing it, you might have damaged the solder for the socket, preventing the plug from getting a good connection.

Also, sometimes when replacing bulbs, other parts such as resistors can fail.

This can be to voltage instability, electrostatic discharge, power failures, and so on.

I would take the new bulb out, and take it and the old one to Fry's, or to BestBuy.

They both seem to have a rather well stocked supply area for bulbs, it could be that even though your bulbs might LOOK the same, they may be quite different as to the way they are made on the insides.

I hope this helps you out some, and good luck!

BenQ DX 650 Won't power up making clicking noise


Those units are designed to be fan cooled after the bulb shuts off. When the cord was pulled, the unit lost power and without the fan, sat there and cooked. Could be a thermal fuse, could be the bulb.

If you hear the Lamp fan turn, it is probably the lamp it self that has failed. If you do not hear the lamp fan turn then the fan could be bad or binding.

Look at the fan and verify its comming from the fan and not the power supply unit, you can clean the fan or replace it, but yes the fan would be likly the problem. Make sure you double check the power supply unit and clean if its needed,

That's probably the Color Wheel you are hearing. When you turn the set on the color wheel has to run, one of the several things that has to happen for the set to come on. The color wheel sends a signal back to the control circuit to tell it it's running. If these sets fail to light the lamp they will shut off and try again, that's why you hear the color wheel start then wind down then start again. The set should try three times before it decides it's not going to be able to turn on.

One way you can tell the difference in the fan sound and color wheel sound is if you can get the set on, let it run for a little while so it gets warm, then when you turn it off the color wheel will start winding down but the fans will continue to run for a minute or two.
