Makvision monitors are manufactured by Wei-ya!

DAMN IT, DAMN IT, DAMN IT, DAMN IT, DAMN IT, DAMN IT!!!!!!!!!!!

I'm starting to get pissed at this dead horse!
 
I've got 3 or 4 of these 19" chassis that are a few years old that died fairly quickly after taking them out of the box (bad flybacks). I have no idea what yoke impedance is needed for them, so I don't know if they're even worth tracking down flybacks to fix them....
 
They are no help when it comes to trying to get information. Or atleast my attempts proved futile. couldn't get any information, schematics etc.. The best I could get was send it to Happ for repair.

Aside from being cheap, and all these replacement chassis being almost identical, I would like to find a solution to the H width problems. There are so many caps in that circuit that seem unnecessary.

I recall there being a cap on the k7000's that you could change that would effect horizontal width. I wonder if these boards have a similar circuit? The pot on the remote board works but just doesn't shrink the screen small enough, right?
 
Wait a minute. There must be something wrong. If Wei Ya's (which are made in China, right?) were made to Makvisions high quality standards, I've recently been told that they are actually the best quality you can get. China can make ANY QUALITY the buyer asks for. So you must have had a fluke problem with your monitor (and the other three the other guy had). GO COMMUNIST CHINA!!!
 
You got it backwards.

Maks are built by Wei-ya to MAKVISIONS specs. So that means that the Mak's are better then Wei-ya.

For whatever thats worth...
 
I just got a pacman and it has a makvision in it, picture looks and all that jaz

I wasnt going to be an ahole and post in the thread you started about your nice Flea Market score but since you joined us in here...

Your lucky that it turns on!

:)
 
I heard something today about the recycled bags that were getting from China having lead in them!

I wonder when they are going to start using Asbestos?

Ha it works now and should last awhile for the little time I play each game

Yeah, you should be fine. So long as the game isnt on for more then a few hours a day.

I've got games that are on 14-18 hours a day so a failure within 2-3 months is what I expect.

Pretty much every monitor has that circuit somewhere. The trick is finding the proper part to change. If you have a schematic, you can look at where those parts are located on the models that we know about (G07,K4600, K4900, K7000) then check that area of the schematic of the Makvision to try to indentify which part it most likely is. I've had luck with that method before...

Ive done this on GO7's and 4900's too. Like you said, its just a matter of finding the right cap and the right circuit.
