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

Take out the bulb (back left hatch door) look to see if the element inside the bulb is broken or blackened - (replace bulb) if the bulb looks OK then it's the ballast that fires the bulb (service call).

You now have a defective lamp ballast board. It sometimes is the root cause of lamp failures in these sets. The problem here is that Toshiba does not sell the ballast board independently from the larger, more expensive light engine assy. Call Best Buy back and get a servicer out there. He may have to take the ballast board out of your TV and send it out for rebuilding.

SOURCE: Toshiba 62HM195, Loud hum noise when TV is first turned on.

I have the exact TV and had the exact same problems. It is the light engine with color wheel that needs to be replaced, and they are VERY hard to come by for this model. Our repairman has had our TV for 5 months and still cannot locate a vendor that carries the part. He said according to Toshiba, the part has been discontinued. If you happen to find one, please post. I'll do the same.

The screen went blank and green light started flashing. Turned off the TV and let it cool. Turned it back on, getting sound but no picture. Red light is on, after about 15 seconds the green light blinks...


Since you say that there is sound but no picture, the first thing I would check would be the status of the lamp. I believe that the lamp has been shattered or the filament is blown. Please verify this and let me know

Toshiba 56PW8 rear projection - lost sound and picture after powercut


The convergence amps in those units consist of two Sanyo STK392-110 Ic's that get hot enough to fry eggs.. If your storm flexed voltages enough it could have easily shorted the amps and/or take either of two pico fuses in the 24v supply line to the amps... If you're not too tech savy this is one for a reliable shop and not and expensive fix. Two Sanyo Ics and a couple pico fuses should be more than $50.00 dollars and a couple hours of labor to put them in... While they're at it have them check the caps in the hyper module and for any ring cracks in the deflection circuit...

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.
