14" 'Atari' Matsushita - I killed monitor adjusting a pot!

[RayB]

I need info regarding the 14" monitors used in Missile Command cabarets. I believe it's a Sanyo, though it could be another japanese make. *Edit* It's a Matsushita.

I adjusted the left most potentiometer yesterday, and it killed the monitor. I'd sure like to know what the pot was and why it would blow parts just by tweaking it. *Edit* Cuz it was the damn B+ voltage!

Yeah, that one doesn't jump out at ya under the Sanyo list.... you have to look through the Atari list to find it.

Thank you guys. Turns out I have the Matsushita and the knob I turned was the B+ !!!!!! No wonder! @#$&*! What kind of engineering is that to stick a voltage pot next to standard image pots?!

Read: Matsu---steaming pile of meadow muffin---a.  I've heard a lot of bad stories about this brand.

Well then, the Sanyo from my cocktail is going into my mini and vice versa. The cocktail will be sold. The Sanyo has a really nice crisp picture (but "foldover" at the top).

Have you tried turning the B+ back down?

Hmmm .. those usually have some form of glue on them from the factory. Which makes them stand out to me when first looking at a chassis.
Unless it's been fiddled with prior to you of course.

Sanyo foldover: replace C406.

Matsushita = Panasonic so it shouldn't be that bad ....

Though really for future use now, there was an answer in a part of your question. The part where you said you didn't know what the pot was.
