    I took the bulb out it was not burned, looked good. Cleaned inside TV bulb area and blew canned air on the half dollar size window. Re-installed bulb then turned TV on and still had blue/purple streaks.



    I guess it must be the light engine. What do you recommend just buying another TV or repairing this one? And if I purchase another TV is the old one worth anything? Also is it possible for me to order a light engine and install it myself or is it very difficult to install requiring specialized equipment?

    My 56HM195 Toshiba DLP TV has blue/purple streaks going from left to right across the screen. Seems to appear in shadow areas but sometimes all the way across the screen. Also the picture is a little fuzzy but color is ok.

    I have a Toshiba 56"DLP TV. Model 56HM195
    The problem is blue/purple streaks filling the bottom of the screen working it's way up to about 3/4 of screen. They also appear as blue/purple elongated shadows running from edge of objects left of screen to right.

Either the color wheel will most likely have to be replaced. Take a closer look to see if the purple coloring is any different then the rest. If colors are bad, change it, if the colors and wheel look ok, then it's time to test the capactiors and the ballast with a multi-tester.

It seems there is a convergence problem. The complex convergence circuitry is failing. It is not something you can fix unless you or someone in the house is skilled at soldering and has some electronics experience. Should be fixed by a trained tech.
For the heck of it try a hard reset first to make sure it is not a corrupted software code. Unplug the power cord for 5 hours then plug back in and power is up. This sometimes works, if it doesnt then it need to be repaired.

This is one of two things, a problem with the optical engine witch would be a 500-600 repair, or the second option and more likely is you have a bulb problem. First unplugg it for a hour and try again (I know it sounds stupid but just try) Then remove the bulb and dont touch the glass, if it looks burnt than the bulb it going, time to replace it. you can order a repacment online at lamp-dlp.com It would also be a good idea to blow out the dust in the bulb chamber with air. Good Luck

    You could do it yourself if your very good with electronics, When mine went out I just bought a new set. The parts cost almost $900. You might be able to sell you old set on ebay for a little to help offset the cost

Printer output has shadows, blurring, streaks, lines, poor color


Seem like blocked hole(s) on the color print head...
Most likely if there is a deep clean option then do it (may need a few times to unblock a hole or never).
Also get the printer physically cleaned up if you can see dusts inside (vrtical lines on color bars).

Toshiba 56HM195 56 in HD DLP Loud Buzzing and color distortion


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..
