Designers Edge security light does not work. It been working for 2 years then it quit. Brought it new. Change 150 w bulb and ballast still not work. What can I do?

is the light setup one ballast for high and low beam ? if so the ballast has gone, probably even the bulbs. replace the ballast and bulbs. some aftermarket ballasts don't last, if you cannot find the right ballast for replacement you will need to replace both ballasts. as every ballast set are set the same and sold in pairs.

If no fan, first you check the fuses.

If the fan is ok, no lights, normally it is problem from the ballast and bulbs. Reference is from below.

Sounds like the ballast is having an issue. The ballast is easially replaced and should be available from www.tvcircuitboards.com

Be sure to check the ground side conn.

Hello... I would start by getting the correct lamp for the TV, and I would advise getting an original equipment lamp. The lamps and ballasts are matched by wattage and operating voltage, and a mis-match will at best cause early lamp failure. The sound you are hearing could be the ballast trying to ignite a bad lamp caused by a mis-match. I hope this helps!

Techman007 is correct here. Lamps have "lifetimes" of a certain number of hours. The lamp indicator is there to let you know that the lamp is likely to fail soon as it has reached its expected lifetime. That does not mean that there aren't lamps that will fail sooner. In your case, the lamp is not producing the amount of light required for a good picture. This is normal for lamps as they age. The light output for all lamps decreases with use. Normally this does not occur in such drastic ways however.

Since you are getting light from the lamp, the ballast is working as expected. The ballast is similar in function to the ballast for a flourescent light, it either works or doesn't.

One other thing that can be checked is the fan area and any glass surfaces for dust and dirt. Again this will effect hte overall light output, but not in such a drastic way. When you next change the lamp, carefully clen any glass surfaces as well as the fan area. Please note that any access to the lamp area should be done after the lamp has had time to cool. These lamps are burn hazards.

i actually had the same problem, what happened to me is the ballast got wet and stopped working. so what i would do is try the ballast from your drivers side and try it on the passengers side. i hope that this helps. if you have anymore questions, let me know.

The ballast for the lamp too should be replaced along with the lamp. If you wish to get some details; visit the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

Hello!
Lamp or ballast(if lamp has been replaced) is bad.
Explanation: green comes on: system works, waiting for light to shine into light engine: no light is coming out of lamp, system shuts down, then you see red! how to determine: pull the lamp out of the unit's compartment. Inspect lamp: bloated stem? shuttered? reflector is not shiny? Chuck it!
Lamp looks good or just been replaced: try ballast. Close lamp compartment without lamp itself. Make sure, door is shut, as well. Turn unit on and listen close to lamp compartment: good ballast will make a buzzing noise, then stop. You've got "red'! No buzzing: ballast quit. Needs major repair! Lamp must be good, for sure, to get to the last part of diagnostics. Conclusion: more, than 2000 hours of usage: replace lamp first!
Good luck,
Alex.

Sounds like the relay in motion sensor. Change the bulb. Rechargeable batteries are no good after 3-4 years also.
