Question about RCA Televison & Video

Yellow, magenta, cyan dots appear on screen

I have an RCA R56WH78. It has recently started having yellow, magenta, cyan dots about the size of a dime show up on the screen. The dots are in line and move slowly for a while before settling near mid screen. I have auto converged and it converges successfully, but the dots come back. Also, we have stink bugs running wild here, one has found itself inside and shows up on the screen. Any suggestions?

I am not laughing but I would suggest if possible from the rear with a light first to see if any of the bugs are on the mirror at the rear of the set inside or the lens This set should have inside---look for that first---anything on the mirror or between it and the screen will be magnified and projected into the picture----it is possible to take a good photo and post it here as well.


I have seen this once before---had lots of little moving specs on screen of a Sony---they had several hundred knats inside flying around that were attracted to the light and warmth there.

Solution in that case actually involved use of Moth balls for a while in the area.

My printer is reading check alignment, is it because my color cartridge is out of ink?


No, that's not what it means.
If printer heads are not aligned, CMYK colors (Cyan, Magenta, Yellow and blacK - the usual colours in a printer) will not print in the correct place.
Assume a dark grey dot is to be printed. For this C, M and Y colored dots have to be placed exactly on the same spot. But if heads are not aligned, the three color dots will not be exactly in the same place. Therefore you will see Cyan, magenta and Yellow dots adjacent to each other instead of one dark grey dot.
It is always a good idea to align the print heads every time a new cartridge is installed.

Took out drum, and yellow cartridge to release jam, cannot get yellow back in


On the topmost part of the printer, there are four buttons in the following order (top to bottom): Black, Cyan, Magenta, and Yellow.

Besides the four button is another button with 4 dots (Black, Cyan, Magenta, and Yellow with a rotating arrow), press this once and you will see that the Yellow button on the left will light up, press it again and the light besides Magenta will light up and so on. Anyway, you get the idea.

Just keep on pressing it until the light besides Yellow lights up again. When it does, lift the top cover of your printer and insert the yellow toner.

Canon Pixma yellow color problem


Either the ink you are using is not going to give the color you want, or you have print heads that are blocked.

Photosmart C5280. Instructions on photo cartridge 348 say remove both black and colour cartridges, then install photo cartridge in right hand cartridge holder. Printer screen then tells me to install...


Your printer uses the following cartridges:

HP 74 - Black ink
HP 75 - Cyan, Magenta, and Yellow ink
HP 99 - Photo Black, Light Cyan, and Light Magenta

You need Photo Black, Cyan, Magenta, Yellow, Light Cyan, and Light Magenta to print photos. To accomplish this you install the HP 99 photo cartridge where your HP 74 black cartridge usually goes and you keep the HP 75 color cartridge where it's at. I don't know why your printer told you to remove both cartridges, then reinstall the HP 75 color cartridge.

Colors are not printing the acutal color


It all depends on the meaning of 'not properly'.

Try creating a document with four different squares, or words, of these colours: yellow, magenta, cyan and black. If all of them print (albeit not with the correct shades) it is probably an ICM driver error. But my guess is that only one of those four colors will print badly, due to a defective color cartridge.
The OKI 5150 makes all perceivable colours using cyan, magenta, yellow and black toners, so if one of these malfunctions, the resulting colors will lack the required shade of, say, yellow, and will appear to be "wrong". The yellow colour itself, of course, would simply disappear (the "yellow" you use might actually be 95% yellow and 5% cyan; then the "yellow" square will be printed as a very light shade of cyan, while the other colors - say, 95% magenta and 5% yellow - will turn out almost exact).

Try with the color test and replace any failing cartridge; if all four (almost) pure colours do print incorrectly, it's unlikely to be a cartridge problem, and we'll have to dig deeper.

Tiny dots about 1 inch apart down the side of page


Again, this was actually HP Laserjet 3800. Problem solved by chatting with HP, and them having me go into a diagnosis mode that disabled cartridge check. Then, I removed the cyan cartridge, the dots went away. They then had me put the black into the cyan slot, and not dots appeared. I had backup toner on hand, swapped in a new cyan and magenta, and all was good. HP agreed to replace the cartridges.

Recheck the placement of the ink cartridges. The black ink cartridge is larger; the cyan, magenta, yellow cartridges are all the same size.

When the ink cartridges were replaced, two or more may have been inadvertently switched or an extra yellow cartridge placed in.

Hp 4600 no cyan printing


Firstoff, if you have tray 1 set to "any size" & "any type" they had problems with it going into calibration to frequently. If you upgrade the firmware this will take care of that. As for no Cyan, check the scanner interlock to insure it is opening the scanner cover. You could also go into diagnostics and disable cartridge check and swap the cartridges around, ie. cyan & magenta, run the print quality pages and see if the problem follows the cartridge. It could also be HV power supply.
