    Actually this just started occurring after a move and change HD satellite input. I had Directv at old house and wanted HD, so our new home had to be wired for satellite. I have tried all inputs on TV, hdmi,colorstream hd,video and antenna. I have my regular receiver installed. You can probably tell I am at wits end. Thanks for your attention to my concern.

    The problem has occurred twice during DVD play, about 1 hr and 30 min.

Save tho old lamp unit. This could be a digital signal problem. Check the cables and connections feeding the TV. Are you feeding satellite or cable to the set? Does a DVD or VCR input have the same problems? That should help isolate the issue.

I have a 72 inch toshiba flat screen tv when turning it on the green light flashes it comes on then go right back off


I have researched the owners manual and it states to recheck the lamp door and make sure the lamp is seated properly and that the door is closed tight. I can email you the manual if you do not have one.

If any of the following conditions exist, turn off the TV, unplug the power cord, and repeat steps 1-9 to ensure that the lamp unit and lamp unit door are installed correctly:
• No picture • Dark picture • TV will not turn on
If, after repeating steps 1-9, the problem still exists:
• In the U.S., call TACP consumer solutions at 1-800-631-3811.
• In Canada, locate the nearest Toshiba authorized service depot by directing your web browser to www.toshiba.ca; click "Home Entertainment," and then click "Support."

I replaced lamp on my toshiba 50hm66 tv and now i got a black and white picture


Hello
As it is a DLP projection TV, there will be a colour wheel to filter colur. If the whell does not spins at all, or spins out of synchronisation, there will be no colour to the picture. Just check the clour wheel. If needy, replace it. Clean it with cleaning solution. If you don't have eneough knoledge in alaigning the colour wheel, just get help fro an expecienced service technician. There is an RPM [Rotation Per Minute] counter to count the number of rotation of the colour wheel. If this sensor has some fault with, the colour wheel won't syncronise to its original speed what it should be, resulting out of colour picture. OK.

My 50hm66 will turn on,picture comes on for about 10 seconds and then the tv turns off.After it turns off flashing red led on front of tv. What would cause this?thanks jim


I had similar problem with my 50HM66 , except it would stay on for at least a few minutes. I cleaned and vaccuumed (with lamp removed) as best I could, I think it's an over heating issue. My TV is 3 yrs old, have replaced lamp once, it did it with either lamp. When I put a fan to the right of the TV so it's blowing behind it, my TV doesn't shut off. Something to try...

Watching tv when the picture went black and now the green on light flashes for 30 times and turns off


A green flashing light for this model of TV indicates that the lamp cover is open on the TV.
  1. Unplug the power cable to the TV.
  2. Remove the 2 retaining screws on the lamp cover with a Phillips type screwdriver.
  3. Remove the lamp door completely from the TV.
  4. Remove the two retaining screws on the lamp case.
  5. Lift up the fixed wire handle of the lamp.
  6. Pull out the handle slowly and remove the lamp case.
  7. Insert the new lamp gently into the correct position. Make sure it is inserted correctly.
  8. Using a manual Phillips screwdriver (Do Not use an electric screwdiver), tighten the screws you removed in
    step 3.
  9. Replace the lamp cover and tighten the cover screws.
  10. Plug in the power cord and turn on the TV. After the initial warmup period (which may take up to several
    seconds for full picture brightness), the TV should operate normally.
If any of the following conditions exist, turn off the TV, unplug the power cord, and repeat steps 1–9 to ensure that the lamp unit and lamp unit
door are installed correctly:
  • The lamp indicator flashes green.
  • No picture
  • Dark picture
  • TV will not turn on
If, after repeating steps 1–10, the problem still exists, call Customer Service at 1-800-631-3811.

The bulbs for this TV seem to go about every couple years. The price has dropped down a bit. I have found it for 118.00.
