My Toshiba 56hm66 Theaterwide HD tv popped a bulb. I ordered a new bulb and installed it and 15 mins later it popped. Is there something wrong with my tv or did I just get a bad bulb?

If your lamp imploded then your product is perm. damaged. You could have a service center come out and try to clean it, however, by the time you pay for that if its not under the warranty then its going to probly cost you just as much as you might as well towards a new one. Also, Toshiba is one of the worst manufacturers that has issue on their HM195 or HM95 series. They had plenty of recalls going on with that series. If you own that model, you might want to see if the manufacturer can do something for you if you are still within the recall guidelines. Use this as a tool: Click on: "Replace lamp" This is Samsungs website, however, replacing a DLP lamp is the same process in every manufacturers products. Use the prompts in the pop up you see from there. See if that helps. http://www.samsung.com/us/support/guides/howToGuideSearchList.do?group=televisions&type=televisions&subtype=dlptv&model_nm=HL-T6756W&dType=D&mType=UM&vType=R# Good luck!

SOURCE: Problem with Toshiba DLP Projection TV Model #52HM84

It is possible the lamps may be defective or that they may be the wrong replacement for this model, as it may have a different wattage setup with the ballast. If you want to try to order the TB25 lamp from a different vendor, you can order the original Toshiba replacement lamp for this model (52HM84) from a major Toshiba parts distributor at the link below:

SOURCE: Toshiba Theaterwide HD 50 inch convergence problem

You will have to spend money to repair it. The Convergence IC's need replacing along with checking all the bias resistors for correct value. Do not attempt to align the Blue manually as you will have a headache once the problem is repaired. A normal repair bill is in the area of $250.00 for a service center to repair.

Possibly bad electrolytics. Generic answer but you didn't give a complete model number.

SOURCE: My Toshiba 52HM84 blows bulbs

Ensure that you don't handle the bulb with bare fingers. wipe the bulb with meths and hold the buld with a lint free cloth when you're putting it in. If it's still blowing it's probably over heating so check the fan

Toshiba TheaterWide 57HM167 Won't Turn On After Bulb Replacement


There is a ballast which drives the lamp--a hint would be to try to be in a position if possible to see if lamp ignites at all or even for a moment.

The ballasts do fail but rarely----it develops about 12,000 plus to the lamp and is much like spark plug wires as far as rf.

Some checks would have to be made and then the ballast priced--google the model number with ballast after it to get and idea.

No cut and dried solution here--several possible causes.

Red light flashing while green light stays on


I have the same TV, your projection bulb has quit/failed.

A loud pop was heard and the picture has gone followed by a red led fault light clicking on and off.

if your tv is less than 1 year old, and you registered it with Toshiba, you could qualify for a free replacement.

otherwise expect to pay 200.00 for a new bulb from Toshiba.

only good thing is you can replace it yourself, only tool needed is a phillips screwdriver.

you can check EbaY for prices less than 175.00 to 150.00
i am on my 3rd bulb within 4 years....

good luck!

Toshiba 52hm84 DLP buzzing sound after replace bulb?? no pic


You have bad capacitors in the power supply that took out the regulator, or the ballast circuit is defective. Not really a repair for the novice. Good Luck

No picture, hear sound, television will shut off after a few seconds.


Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.
