Flyback
...i replaced my flyback as a good measure to bring the Polo up to date, that has led me to the frying resistors you commented on in another post. The old one is still good so i'll try sticking that one back in. Glad I kept it.
Let's bring this post back from the dead...
can someone tell me what the number and ohm value for the small resistor below R227 is? R227 is the large 10W resistor near the transformer. I had sold my Polo to a guy and it worked great for a month or so and all of a sudden blinked out with some...
Success!
OK, Everything looks good to me now so I'd thought I'd share my success and say thanks to the guys who have helped me along the way.
The Polo looks good and is in the cab. After I got the heater working I did a cap kit and noticed that I couldn't get the monitor brightness up at...
Does you heater get any glow? I just finished up a Hantarex Polo that had same problems. Once I traced out the components that were bad I got the heater working and things started going positive.
Don't know. I was just curious as to if there was one. You'd probably see a place for it if there was. It doesn't seem like there are a ton of people on here that like talking about the hantarex stuff. Ive heard a few horror stories haha.
I have read in a few places that a non-bright monitor and blurry edges can both be signs of a bad flyback. I mean, this things doesn't look brand new. I think I may try ordering a new one and seeing where that goes, does this train of thought sound right?
Hantarex (WORKING Moderately now)
OK! the good news is that I have a picture on the screen now. I capped the monitor, replaced the B+ filters, fixed a few traces and broken solders etc. Maybe something else that is minor.
Anyway where I am at right now looks like this... The monitor is dim...
UPDATE - Progress!
O, Here's an update for those who feel like following. Please keep I am no expert at all so there are many things I don't know about monitors. Some simple solution I may be missing.
I replaced my B+filter caps with the 470uf version as well as a new HOT I ordered - same...
I have two cabinets for sale as seen in the pictures below. Location: New Orleans area. Both work great. Both monitors have been recapped and look good. One monitor was DOA when I got the machines months ago but everything is in working order now. The cabinets do not have the seat units. I...
What;s up with your polo? Hopefully we have some similar problems. If you haven't, check out this guide Mecha wrote the other day, it's pretty helpful. http://forums.arcade-museum.com/showthread.php?t=249495&highlight=polo
I've been commenting on an awesome Polo post by Mecha but didn't want to hijack it any longer - I need to keep track of my progress.
I guess I'll run down everything step by step and maybe someone can help me figure out what next to try out.
Hantarex Polo 25 Monitor - Blind. I have no game...
My polo 25 has 330 uf B+ filter caps, your guide shows 470 or something. This thing has had some work done to it, so is the 330 uF caps the correct ones? It's in high voltage shutdown right now... but was powering up before I replaced one of the 330's that was all bulged out as well as the HOT.
