Question about Toshiba 56HM195 56" Projection HDTV

Open Question

Toshiba 56hm195 HD TV. Buzzing sound started a long time ago. Comes on w/power and shuts off after TV completely powers down. Now sometimes when I turn on TV 1/2 screen is blurry grey and the other side is showing the picture but flashes between clear and distortion (almost like a picture negative) It is happening more and more. Is it the lamp or colorwheel? Can I replace what I need to by myself?

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

SOURCE: Toshiba 43A61 - No Picture, no sound

If your set all of a sudden won't come on, e.g., the screen is blank, but the LED on the under the screen next to the on/off switch keeps flashing, then there may be an internal fault on the set that needs to be reset.
To force the reset, try this:

  • Unplug the set and wait a few seconds
  • Replug and see if the video returns
Whenever the set senses an internal fault through its monitoring circuitry, it essentially shuts down the set. The flashing LED provides the indication that a fault has been detected. Removing power to the set resets the monitoring circuitry. When plugged back in, the circuitry again does a check of the system. If it finds that there truly is a problem, then the set is shut down and the LED will again flash. In this case, you need to call a service tech. Most of the time, however, the unplug/replug routine is enough to get the set up and running.

If the sound, sounds more like a Hum with some vibration chances are the Cooling fan located behind the lamp is going bad, about $20 to repair, if its a high pitch hum most likely the Color Wheel and if thats the case about $30.
Good luck, my fan just went bad now seeing green dots everywhere, so debating on just junking it out or fixing it, with winter coming on might just breakdown and buy LCD and say the heck with DLP from now on.
Good luck to you..

I have a toshiba 56hm195 and I replaced the bulb about 9 months ago. Now when I turn the tv on the light just blinks and does not come on


If I'm not mistake is there two lights red and green? Can you give me some detail on which light is blinking, and how fast (1/3, 1/2, 1 seconds apart)? I have a feeling it the green light and 1 second apart. LPS mode (low power shutdown) mode. Problem with USART signaling power not being able to power up ballast. Truth is it could be a lot of things but, I'd start looking around there first.

56HM195 Light Engine Troubleshooting


you should make sure that the onscreen menus are effected by the problem if they look OK and just the video bihind them is distorted the problem is in the digital video or what Toshiba calls the seine module. Probably not though it sounds like an engine. PTS electronics rebuilds some engines however most Toshiba engines are relatively reasonable.

TV Shuts off, Screen Problems


The problem could be the power supply, the flyback trasformer or simply a bad connection. A repair cost for this TV set could run any where from 75 bucks all the way up to 225 or so, depending on the problem. Good Luck
