Question about Televison & Video

1 Answer

I have had a total of 3 blown bulbs. The last one worked for about 5 hours. When I woke up the next morning and turned the tv on it made a loud cracking sound and the bulb busted. What could be causing this before I put another bulb in?

Every set that uses a lamp for brightness has a ballast----it essentially provides power to fire the lamp----power in to the ballast will be around 300 volts DC in most sets and the output to the lamp over 14,000 volts with lots of RF---like spark plug wires.

SOURCE: Toshiba 52HMX84 Sound no picture.

It's not a 1k Resistor but a 10k...it's the resistor R3 on the Circuit Board Part Number RPB-4434ZA (P/N: 23122468). If you don' replace the resistor you will keep burning your lamp. If you decide to replace the resistor by yourself...you should take the time to look at all the on the back of the board.

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:
