Boosting Amiga video port's RGB signal possible ?

[Jose]

Hi. Some TV's/most monitors (when using VGA with AGA or ECS), don't have color control. How can one boost the RGB signal to have more intense colors for in my Nokia 446Pro monitor and my TV the color intensity is too weak and they don't have color controls (TV does have it, but it doesn't work with RGB Scart connection).

I thought about opening the TV and messing with the color amps on the tube but, besides being extremely dangerous, I fear screwing up the tube's settings and not being able to put them back.

"Good luck :-)"

Yeah, I hope I don't get fried :-o  :-) I'm really tempted to do it. I'll open the TV and see if I find any info on the tube's settings on the net...

"If you are not familiar with the innerds of a TV, stay well clear."
I'm not. :-)

" Also a lot of modern TVs have no internal adjustments that are of any use. There may be RGB gain controls on the board on the back of the tube if you are lucky, but if you do not know how to recognise them, don't twiddle."

Mine is not modern, it's a 15 year old Sanyo. But I was told by the technitian that last repaired it, that it has a processor that controls inputs or something. Not sure it it has RGB gain. Nothing like opening to see.

"The board on the back of the tube usually has at least 1000 volts going though it, (which is nothing compared to the 27 THOUSAND volts going to that rubber sucker that us techies call the anode cap)

Scared yet ? You should be"

Cool!! :-D Seriously, of course I am, I don't plan to keep the TV on or even plugged into mains when I'll open it.

If there's another way around it let me know...

Guys, thanks for your concerns really!! I'm aware of the danger and I'm not gonna do anything silly. If I open it and find out that it has some obvious settings like r, g and b gain you can be sure I won't try to change them without being HYPER properly isolated.

Hi. After a few hours search the other day I found RGB booster
Do you guys know of any similar circuit ? What's the result like is there a degradation in image quality ?

P.S.
No, I still haven't opened my TV, once people here finishes vacation I will do it ( so I still have a couple of days to live..:roll:)

What I need is another TV..
I think I'll leave it, not worth the time, I probably won't be able to do anything...

Great! :lol:
There was a time in my father's life, around 30 years ago when he fixed very old CRT's. He once toutched one that was on and got knocked inconscious for like 10 minutes  :-o
