Question about Toshiba 42H81 42" Rear Projection Television

Negative looking white screen picture

When the picture is mostly white or light in color it shows like a negative but the rest of the time the picture is almost perfect - just goes a little wavey sometimes. Any idea how much this will cost to fix? Thanks! Q2007

This tv has many problems in the scan converter/hyper bd. the wavy picture is very common the problem with the white not so much. However, I have seen them cause many odd looking video distortions and I suspect this is where your problem is. The part is usually kind of high, 250 + Labor i'd guess. If you get it somebody good they can probably repair the bd rather than replace it and save you some money. Either way i'd plan on 300-400

Everything that is supposed to be black is showing


Hi,It sounds like a problem with the color wheel or DMD board. The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will hear ,humming,buzzing,high pitch noises ,you might also experiment color distortion ,black and white picture. This is how the DMD works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

How do i connect the casing power to the motherboard


Open ECS web site and download the manual for your MB, P4VMM2 V7.3; http://www.ecsusa.com/ECSWebSite/Products/ProductsDetail.aspx?detailid=333&CategoryID=1&DetailName=Manual&MenuID=1&LanID=9
You will need Adobe reader to view the manual if you currently do not have it. Download and install Adobe; http://www.adobe.com/products/reader/ With Adobe you can zoom in and out to assist you in connecting your case to the motherboard. Start with page 9. Page 12 and 13 shows you how to connect your case LEDs to the motherboard. Pin 1 is positive for your HDD_LED. Pin 3 is negative for the HDD_LED. ECT. Most wires coming from the case are inserted into a jumper and most jumpers are marked. Ex: HDD for hard disk drive, RS for Reset Switch, PW for power on/off switch ECT.
The case wire colors do vary from case to case. The wire colors blue, light blue, green, light green and red are most common to be positive. The colors white and black are common for negative. Below is a picture of a typical front panel case to motherboard hook up. Less the white standoff jumper block.

Your board uses an internal speaker. Connect the red wire to pin 1 and connect the black wire to pin 4. See page 11 for location and page 12 for connection.
Use the manual. Its a great guide.

Happy holidays!

My scanner will not scan negatives


Most scanners aren't designed to scan negatives. (Of course the manufactures would never want to tell you their product CANT do something).

Flatbed scanners typically have a light on one side.

To scan negatives properly, you need to have a scanner that has a backlight, or a second light in the bed's lid that you fold down.

Canon USA, Inc. make a few flatbed scanners that have backlights. They range from $60 to $180, depending on the features and resolution you want to pay for.

Please see the below link. This is a more expensive one, but is shown just so you get the idea. In the pictures, note specifically in the picture that shows the lid open, how the white backing on the lid can be removed from a clip at the top. Underneath, is the backlight and clips designed to hold negatives in with the included frames.

Black and white screen...


The color wheel can cause a black and white picture but not the jumpy or negative look.
Those symptoms are usually caused by the DMD assy which drives the color wheel and is somewhat expensive, most of the time you can purchase the whole Light Engine which includes the DMD assy for the same price.

White balance problem


My experience is that in geneeral terms white balance of the C765 is almost perfect. The earlier C740 did have a purple color in the white areas. The pictures need most a light push on trigger to first set up all correct. If you do so it should be nice colored. Olympus own xD card is required to make panorama pictures. Several pictures can then be set together within the PC software Cameras
