I think I have the same TV darker color not as sharp
I had a service tech. look at the TV and he told my wife we have algae in the red and blue tubes and that they must be drained and new fluid replacing the old, is that true? I never heard of fluid needing to be replaced or in the tubes for that matter.
I was told the guns just need to be adjusted?

YOU HAVE ALGAE IN THE BLUE AND GREEN TUBES IT DOES NOT GROW IN THE RED TUBE TAKE OFF THE FRONT COVER AND LOOK IN THE TUBES COMPAIRE IT WITH THE RED WHEN IT IS ON WITH A PICTURE WILL NOT HEART YOU TO LOOK IN THEM WITH IT ON DONT TRY TO FIX IT YOUR SELF
If you are running component video, make sure the blue is plugged in and in the right spot. Component video works like this: the green is a black and white image, the red and blue are cover overlays to make the image display properly. So if everything looks plugged in right, then try plugging in a composite video (Yellow) or S-video cable switching to the appropriate input, and see if the image is still red. If so, go to the set up and set the set to factory defaults, and see if that fixes the color issue, It's possible that the color settings on the TV are messed up, with the S-video plugged in go through the set up menu and see if you can correct the color issue IF THE IMAGE IS STILL RED WITH THE S-VIDEO OR COMPOSITE VIDEO, otherwise the issue is a problem with the component video cable.
I don't know about the buzz but when you need to replace the coolant it isn't the coolant that actually gets blurry, it is algae that grows over the crt. It kinda looks like snow if you look in there, maybe a tannish color on the blue tube. Usually only grows on green and blue tubes as plants don't grow under red light. Lots of directions available to replace the coolant but my recommendation would be to tip the tv over backwards, pull the plastic focusing assembly clean off catching the old coolant in a cake pan. Be sure not to let any leak on boards as it is conductive. Once those are off you will be able to wipe the CRTs off with a soft cloth. Pretty easy to fill them back up with a small funnel.
If you don't see any algae in there, there are six color coded dials that adjust focus electrically and brightness.
The most likely cause is the blue and green tubes need to have the cooling fluid changed. After many years the blue and green get clouded with algae. The red tube won't have the problem due to the red spectrum kills the algae before it has time to grow.
The way to replace the fluid for is to completely remove each CRT from the set, remove the drain plug, drain the fluid out the tube, disassemble the lens, give it a good cleaning; then reassemble; add fluid; and reinstall in set. If you check with the site www.TvRepairKits.com they are working on a kit that includes the fluid and photo instruction guide.
Your missing the red drive on the set. Its most likly the picture tube. Its a possibility that the red drive circuit could be not working so the best thing to do is take off the gree picture tube socket and put the green board on the red tube. Of course do all this when the set is unplugged. if you have no tv experience. its not a good idea to be messing around inside of these sets.
