I have a Toshiba 65H80 that has poor color. It looks almost as though it's a black and white picture highlighted in yellow. Blues show up, but no red and everything else has a yellow tint

    The picture is sharp and clear, blue objects are accurate but there is a yellow tint to everything else. If was a convergence problem, wouldn't there be blurry edges on graphics or other geometric shapes?

Try going to the menu and selecting the color bar and setting the yellow color lower than the rest (if you can). If you do not have just the option to change the yellow color, you still should have a regular color bar to change the different colors. After the color has been changed to fit your needs, there should be less yellow. It should be fixed then. Your menu option for the color may have reset itself.

Try removing and reinstalling the lamp to make sure that it is seated properly. Have you ever touched the optical assembly mounting screws? If so, its possible that its misaligned. If reinstalling the lamp doesn't fix the problem, then most likely the Optical block is damaged and needs to be replaced. If you have any questions about doing this let me know, but it looks like it may be a little project that you got if the lamp isn't the problem. If you need a place to order a new optical block from, let me know and I will post a place to get one from within 24 hours of your post.

I own a toshiba 19dv500 and am having trouble viewing a dvd, the system is working but only in black and white, no colour\???


Hello there,

A black and white picture is most often due to a faulty or incorrect RGB (red/green/blue) connection or cable.


If you are using a composite connection (red/white/yellow RCA jacks), you have probably connected the yellow plug to a socket labelled Pr/Pb, Cr/Cb, or Y - on either the DVD player or the TV - most probably the TV. The yellow needs to be connected to a socket labelled "VIDEO". If you connect this to any socket labelled Pr/Pb, Cr/Cb, or Y, you will get a black and white picture.

If you are using a component connection (red/green/blue RCA jacks), one of the plugs is either not fully inserted into the socket or is in the wrong socket. If you remove any one of the R/G/B plugs, you will get a black and white picture.

If you are using a SCART cable (UK / AUS), you may have a bent, damaged or disconnected pin.

I suggest you check and correct the connections between your DVD player and TV. If you are unable to locate the problem, please try another cable as the one you are using may be damaged. If you are still unable to locate the fault, please let me know the brand and model number of the DVD player and how it is connected to the TV. If required, I can also draw a diagram showing the correct connections.


It would also be useful to know whether this "fault" suddenly occured, or whether you have just connected the player to the TV.

Hope this helps - please let me know if you need further assistance.

Regards,
BElectric

Color Wheel


I'm pretty sure if the color wheel spins with no vibration that it's not the colorwheel. I would have to say that your cable is bad. If it has been bent repeatedly near the connection that the wires could be breaking down. Try a brand new cable.

Happy Spring.. I have a C7280 all in one..It is not printing in color...the pictures come out faded in black & white.. All my color cartridges are full...except for yellow..that is not completely...


You may need to clean the print haed. A self test report will show this, if so do the following

To clean the print head from the control panel
1. Load letter or A4 unused plain white paper into the input tray.
2. Press Setup.
3. Press to highlight Tools, and then press OK.
4. Press to highlight Clean Printhead, and then press OK.
The HP All-in-One cleans the print head and prints a page that you can recycle or
discard.

Service man says light engine. how much? jvc model hd52g886


Whites are yellow can be a convergence or color balance problem, and lamp going out could also be a bad ballast board, black spots are usually light engine, could be a different fault on DMD board.

The fact is that when you get all this symptom together unavoidably you have a faulty light engine.

The light engine is the most expensive part to replace, its price for this model is always over $1600 ( I know, keep the heart tablets at hand).

Here is the part for your model: TS-COP7A-SAA-R

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 65H80 has yellow hue.


Check you HD inputs or source. Sounds like the red stream is missing; maybe a loose cable.
