How calibrate a VCR?
I have a Daewoo model SD-7500, and already try cleaning the head, but I still having problems with a video tape: in this tape the image jumps, I try clicking with the keywords "+" and "-" in my remote control to better the image, but don't works.
The vide tape seems clean without that withe thing:

Have you tried with a second tape? And do you have an osilliscope? Cuz you'll need one if you want to run an align.
tapes that were recorded wrong can't be played back right

Nope, this tape was record in SP. In my last VCR I had, I never have this problem with this video tape in particular.

This only happen with this tape in particular
>osilliscope
Nope, I don't have that.
Also:
I found this screws and I discover if I move more or less, the image change and too the audio, but I can't find the combination right to this video tape.
OP Here, the screws I found from the Audio head (A/C Head)
But I don't have idea why when I touch this screws the image changes.

Have you cleaned the actual video heads (not the ones with labels)?
>inb4 you have broken them.
Easy to do if you do it wrong.
>>928930
Yes, I clean everything.

I doubt he'd be able to point out the playheads out if asked. We had a lackey on our service bench who used to clean the entire drum but skip the head chips because he thought they were cooling vents for the drum motor. He knew to use cardboard strips as opposed to.. well.. anything else, but didn't know why.

So.. You're looking to align your deck to an obviously faulty tape? I don't understand..
> But I don't have idea why when I touch this screws the image changes.
So you know it's called a control head, but the presence of the word "control" in it's name doesn't tip you off to the fact it may have something to do with controlling the payback of the tape? Did it occur to you to google "VCR control head" so you could read about it and it's function?
I think you should put the lid back on this unit and walk away anon, it appears to be perfectly functional based on what you are saying, and if you have no scope, you have literally zero chance of aligning this thing correctly.

>cooling vents
Lol.
>zero chance of aligning this thing correctly [without scope].
If he can turn auto tracking off there is a very good chance of doing it adequately at least. I still suspect a proper clean has not been done and until any other adjustments are more trouble than they are worth.
