    My TV had the same problem! Some people said 'Light engine' might had problem. What's that?

    How can I remove the old ballast on this Toshiba and replace it?  No instructions are with the TV manual.  I have tried for hours to get into the section that houses the ballast.  Changing the lamp was easy.

    I think I have a similar problem. I've had my Toshiba 52HM84 for 40+ months and I'm still on the original lightbulb & ballast. Tonight, the tv just shut off (out of nowhere) and the start-up lights starting going from green-to-red and the tv started starting up and shutting off, however with no picture. Has the bulb gone bad? Or has the ballast gone bad? Do I order both parts? Any assistance would be appreciated.

52HM84 Toshiba DLP with apparent failed lamp (replaced ballast)


I found R3 on the original board to be open, along with reading an open on CR1, D5 and D6. All the other transistors and the transformer check out. The only thing I have to do now is find out the specs of the diodes. The replacement board also had CR1, D5 and D6 open (R3 was OK). There had been some threads on various locations where remanufactured boards had bad components (the transistors were changed but not some of the other components).

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:

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
