The picture has faded, and is getting harder to see

PLEASE BE CAREFUL WHEN DOING THIS PROCESS!!! YOU WILL DESTROY YOUR CIRCUIT BOARD LIKE I DID IF YOU DO NOT TAKE YOUR TIME OR ARE CAREFUL!!
What you need to do is clean the CRT coolant inside the TV. Here is a forum that I SHOULD have read before doing mine:

CRT COOLANT REPLACEMENT AND CLEANING

I was lazy and not taking my time to take care in not dripping any CRT coolant and some got on my circuit board, ( I felt confident since I had changed the Blue CRT 2 years prior) and I was only able to see about 1 hour of the best viewing my TV has ever given me since it was new, it looked like a miracle had happened. My TV was "dull" as the best way to describe it, colors faded, kinda fuzzy. I briefly researched into it again to refresh my memory then jumpted right into not really taking any precautions. I got lazy and didn't take out the CRT's like I did the first time with the Blue CRT and paid the price for it. Let me tell you, theirs nothing worse than getting a perfect brand new like picture only to loose it and hour later because of carelessness. Take out the CRT's, take your time, label everything and take pics, the reward is WELL worth it. Oh ya, you can use Mineral oil instead of the coolant that they sell at stores. Its not conductive, and dose'nt damage the circuit board if u spill a little. I used Baby Oil the first time I did it and when I went back to change the green CRT this time around it was still crystal clear, no discoloration in the Blue CRT I had done 2 years prior. I hope your results come out better than mine did!!

The blue CRT could be defective on your TV or the CRT assembly.
How many times the LED blinks before shutting the TV down?

something similar to this happened to my old T.V, with mine it started to go wrong colours, the screen started to fade, with it being 8 years old, you may just need a new one, they will eventually fully break, so its best to get a new T.V

Replace the CRT coolant if its a phillips. Or if a sony it may need to have the CRT drive adjusted for the Blue

Apparently you might need to because scanners are most times not reserviceablw when problems of faded output and discolouration is evident.

Properly clean the surface of the scanner and leave your scanning image application to default settings

I gotta love it when people make up answers. There is no such thing as a "contrass module". I'm assuming the poster meant "contrast". The trouble is your 12-year-old picture tube. It's gotten weak and isn't getting as bright or sharp as it used to. Picture tube manufacturers estimate the useful life of a tube at about 7 years today. There are adjustments inside that might help some, but you need a new picture tube. It's going to cost a lot more than $60 to $75 for that. You're better off replacing the TV.

Three guns Red Blue and Green in the picture tube of an old CRT set. If one of the guns goes out it effects that color. Sounds like one of the guns inside of the tube is going out, To costly to replace for such an old antilog set that will have to have a convertor box next month anyway.

Try unplugging it for a minute. You will have to go through setup again (most likely).
Some of these sets have a (software?) issue and the audio drops out maybe once or twice a year-at least that's what I've experienced. No real fix for it.

So, where are the answers?

I would have to say it does sound like the CRT is reaching its end. The thing that points this out that the picture gradually gets a little bit better as it warms up. It most likely isn't worth the cost to fix it.
