Question about Televison & Video

Toshiba color wheel

Color "ghosting" in parts of picture. The pattern is irregular as if the color wheel is out of sync in parts of the picture. The result is a blue shadow to the right most of the time. Is this fixable or worth fixing in a 72HM195?

You do have a failure in the convergence circuit of your set. If you are good at soldering you can replace the IC's yourself. They are on the large circuit board on the left side of the set looking from the back, and attached to a large aluminum heat sink. If you don't feel comfortable doing that, I reccomend removing the board and sending it to PTS corp in Indiana. They are pretty reasonable repairing boards, and a lot less than buying a new one.

Replace the convergence amp IC's and call a good TV Tech this time. The last tech over charged you about $1000.

We have just got Toshiba projection tv tw40x81 from a friend and the colors are not sharp and pinky looking. Why is that? How to fix that?


That sounds like it could be a color wheel. The color wheel controls the color on your picture since the DMD chip only creates a gray scale picture. You'll need to do a little more trouble shooting. Color wheels can cost around $100. They can be replaced on your own, but it's kind of a pain to get to.

My projection tv has ghost pic you can see three dfferent color lines


Go into the tv menu and look for "convergence" this is a setup issue that can sync your colors. Projection tv's have 3 projectors inside, each a different color, if they get out og sync it can cause a blue or red ghost. In your tv menu you can look for noise reduction and turn it on also scan velocity modulation turn that on as well. These can all be found in the menu under picture or setup.

Samsung DLP HL-R4266W..no sound or picture. TV is completely dead


Assuming the noise is a high-pitched whine, then yes, it is the color wheel.  If the color wheel goes out, the TV will turn on for a while, then turn off when it can't establish color wheel sync.  The color wheel has to be in sync with the mirrors on the DLP, so if sync can't be established, the TV turns off.
You can order a new color wheel from Sears or partstore.com (among other places) and replace it yourself, if you are so inclined.

I heard a pop and now the projector only shows black and white.


The color wheel has failed in youtr projector. There are 4 pieces of glass in the color wheel which fit togeter in a "pie" formation and they are red, blue, yellow & clear. This wheel is spun by a motor. The glass is glued to the motor's hub, and, when it fails the glass segments are thown off the hub. This gives you a B&W picture because all of the light is allowed to shine through the optics all of the time. Replace the color wheel with Toshiba part no: 23125963. It will be about $65. No soldering is involved, just use care with the ribbon cable to the motor. You will need a no. 2 phillips screwdriver and a set of jeweles screwdrivers to do this.

Toshiba #62HM95


I am wondering if this sound might be your color wheel spinning. The color wheel often makes a low humming noise as it spins. Try checking to see if this is not the source of your noise. You need the color wheel to generate the colors needed to turn the B&W picture generated by the DLP into a color picture.

Thank you,
