    Yes I am only a few months into a new bulb and the TV shut off mid movie tonight without warning. Unable to get the set to come back on. Push power button and the red light goes to blinking green but NO PICTURE! At this point, I don't think it is wise to invest much more into this TV but I wish someone had a relatively quick and not too costly fix.

Usually indicates a bad or defective bulb. If new, it was manufactured defective. If used, it is usually due to excessive heat.

The ballast used to ignite the bulb could also be weak, but usually it turns out to be the bulb.

There is a method to increase the bulb's internal fan speed to aid in additional cooling and prevent overheating, but will also allow more dust to be drawn into the TV if the air filter is not sealed tight.

Power button blinks green about 1 minute then goes red


There is an additional problem,

if the bulb had been replaced by a technician, call them back and ask for additional support, since they did not fix the problem.

This could be the "thermal fuse" which usualy is next to the light bulb. Part cost around $5.00. Please check your manual for directions depending on light and times blinking.

The lamp light would be solid red if the lamp were out. The steady blinking green led is usually caused by failed capacitors on the DM board. You can get the V26 dm repair kit from www.tvrepairworld.com which should repair that issue. The kit contains the capacitors and the CD with detailed instructions.

The Bulb in the unit needs to be replaced. To confirm, look in the manual for the set and it will explain the flashing lights by the numer and duration of flashes. Hope this helps.

Toshiba HMX94 DLP I replaced the bulb after it crashed and now red and green light flashes no picture. Please help. I tried two new bulbs. Mark T


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 DM is failing to complete the boot sequence thats why the power led is continuously blinking green. The V26 DLP DM repair kit will usually repair that issue you can get the kit at the following link which includes the replacement capacitors and step by step instructions with pictures on how to do the repair.Its listed under the repair kits category.

Green flashing light - no picture


If the green power light is blinking and you have no picture, then your light bulb has burned out and needs to be replaced. It is not a cheap bulb to replace. If the TV is less than 1 year old it should be covered by the warranty
