19" G07 Arcade Monitor Repair - Partial Vertical Collapse, B+ Adjustment
HTML-код
- Опубликовано: 2 окт 2024
- UPDATE: After the video was already uploaded, I had gone back and did the updated reflow I mentioned I was going to do, but after powering it back up afterwards, it was in high voltage shutdown. Inspection found D905 off the B+ pot had cracked in half. It was one of the components I had reflowed and I think it was a marginal component and just the heat from reflowing it caused it to completely open in half. Replaced D905 and it's back up and running great again.

Mike wanted to Thank you again for all the knowledge I’ve gained from your videos. I re caped my first D9400 and replaced fly back . Still didn’t work but I followed your advise and checked power supply Ic. It check out ok but I replaced it anyway and it came to life. Thank you again keep to videos coming
Sweet! Glad I could help and thanks for watching.
I love your channel! Classic arcade repairs on RUclips is also very helpful
Thanks!
Nice fix as always sir! VERY much looking forward to the Time Killers cab build, def a fun one in that gory 90's fighter era! Can't wait to check out your last build too, love the electronics stuff the most but cab builds are always a great watch too! Thanks again for posting Mike, goin over the the Bloodstorm vids now! :D
As a retired tv and audio tech I can tell you that you never count your chickens before they hatch. I too had the partial vertical collapse, and usually it would be a faulty electrolytic filter cap. I never thought of looking for the last thing it could have been which was a broken vertical height potentiometer. someone tried to adjust it and must have pushed on it too hard and loosed the back side plate and broke it off. both transistors were checked to be good compared to a new one. I did find a couple of bad caps, including the crt cap (completely shot). anyway now I'm searching for something that back in 70's, 80's were common parts, but now they're called "vintage" and are hard to come by. I'm looking for the "vertical Height" potentiometer 200 ohm. I'm just wanting to fix it and sale it. I don't have anymore old tv sets to cannibalize like the old days. LOL, Any help appreciated. BYW, it's the same chassis your working on this video. But it goes to a Aero Fighter upright arcade machine
oh wow !! FYI you have sticker from Laniel Amusement. Is sooooo very funny for me because is from Montreal, Quebec, Canada and i live in Montreal, Quebec
and S/O to your RUclips Channel
Cool to hear the reflow picked up another potential failure along the way
Smeggin awesome documentation Mike !
Great video as always Mike. Are you currently accepting repair work? Got a doozie of a G07 CBO that’s in a bad way.
I am trying to track down why my k7000 blew the HOT. I did the lightbulb test and got 117v off the blue wire of the b+ resistor. My light bulb measure 57w power draw with a watt meter off a standard power outlet. Should I be concerned that its not 123v?
No, the lightbulb test is just to verify the power supply is working. B+ should be measured when the chassis is on the tube.
Love your repairs! Always fun. Time for desoldering station though. :D (I will keep saying that!)
ps. Love that you make those custom cabinets for Time Killers and Blood Storm.
Hello Mike can you please repair a Hantarex Polo chassis.
I’ve repaired many of them on the channel.
@@MikesArcadeMonitorRepair I'm sorry i ment to say can you repair my Hantarex Polo chassis. I took it to PNL before and they told me that they don't fix Hantarex Polo chassis.
