hello,

See Here:

as well as in your manual. Sometimes the lamp must be reseated
by removing it and reinstalling it with great care making certain
the door and all the gaps are closed tight.

If the lamp replacement or reinstallation does not solve the
problem you will likely need a service tech to look at the tv
as there are few user serviceable items for Plasma sets. Most
of the repairs are done by computer connection that downloads
the error messages and interprets what went wrong.

Hope this helps.

The buzzing is the ballast arc gap,normal sound. When the tv starts does the lamp start to come on. Can you see any light from the back? Sounds like bad ballast. Unfortunatly this part is no longer available. the light engine will have to be removed and sent to Toshiba to be rebuilt.

Hi,
Your TV requires ballast power supply board that gives you buzzing noise when TV turns ON.
Ballast supply board is available in Part Store and replacement of that board requires expertise.

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:
