It may be your light engine.

The problem most likely is with either the lamp ballast or the light engine. The lamp ballast is the part that provides voltage to the lamp unit and is usually not all that expensive a part. The repair cost from a service shop can be about $300 or more. If you are handy, you can replace it yourself. Check out www.thepartstore.com for the ballast.

The problem is either the lamp ballast or the light engine. My guess is the ballast. Part cost ranges between about $75 to $150 depending where you get it. If you're handy you can replace it yourself. I posted the process elsewhere on this site for another Toshiba DLP question (I think it was for a 46HM84). Good Luck.

Seems like you might have a bad CAP " capcitor in your powers supply unit. How you can tell this? Opening up the unit and do a HI POT test on your power supply unit and check for faults. You have to be qualified to check this and know what your doing otherwise you could recieve a nice jolt and pay a few hundred for a EMS to revive your heart. So leave this one to the experts if you do not know the logistics of this issue. Assuming your asking me a repair tech would consitute you do not know whats going on seek qualified help.

1. replace powersupply unit
or
2. Rebuild power supply by replacing the caps inside that have tested bad.


Good luck to you on whatever your situation may be but as always Thanks for asking me first!!!

Howdy;
Double check the Lamp installtion. 2) make sure the Lamp DOOR is properly closed. 3) unpug TV from a/c outlet for about 5 minutes. pug back into a/c source.

Are you sure the green light is blinking and not the red light?
