FS Egret 2/Windy 2/NNC/Q25 (Repair refund)

[mdk]

Just chiming in, Grant fixed x2 chassis for me as well both 7534's. One of the flybacks was dead and the other original was working but asked him to remove and replace with the substitute and keep the OG one preserved. This was in 2019 and the chassis are still running perfect, the cabs came from g60hot who was bringing cabs into the UK at the time.

g60hot's first set of cabs (including E2 and Windy) also came from yaton.

How can I pick the brain of the great Grantspain? I can do my own repair with a little bit of help from him. Already fully recapped, replaced hot, flyback, and transformer by the hot. Just wondering if Grant knows of any other parts like the film caps that fail?

Thanks

Don't know how active he is here (or what his handle is even), but you can find him on Arcade Otaku as grantspain.

He is also on UKvac as gunblade if you need to get in touch.

Correct, I went to collect in person and saw the trade mark stickers. The Windy's were filthy and needed a full strip down but they are a resilient cab and clean up nicely. I didn't bother with the Egrets as they looked rough and much preferred the look of with Windy at the time.

On mine I’ve done recaps, flyback change, and it still only lasted about a month. At a certain point I got tired of spending time and money on the chassis and went with nanaos. I’ve yet to have an issue with them that I couldn’t fix or have fixed.

My PB-7534 turns on now but only shows no image.

Tricky times. I’ve experienced weird stuff where a 15Khz game will sync but a 31khz leaves me with a blank screen. This was on a 2931. I’ve also had perfectly good tubes not come on after weeks or months of just sitting there making me think chassis was broken. That was when it was a bit cold and high humidity. I put a hair dryer over the chassis and tube to get it all nice and warm and that got it going. I’m waiting for my 7534 to be repaired by a very experienced repair guy. If he gets it going I’ll do my best to report back to you what was going on.

the board I tried does both, I tried both 15 and 31khz with it to the same result.

Theres soooo many inner working circuit blocks and failure modes on really any crt chassis but the later gen ones tend to be even harder to work on as the tech evolved more.

You really have to know your shit if its outside of a simple fix or something sadly its the way it goes sometimes. You can fix alot with good understandings and simple fixes but once it goes beyond that into actual board level repair you REALLY have to know whats happening and the lack of schematics and service guides providing wave forms flow charts etc really makes that process way more complicated and slow if not next to impossible if only for the most devoted of servicemen.

Funny thing about some of the toshiba chassis's is that they seem to be almost a copy paste of some of Nanao's stuff. Idk if that was like on purpose or what. Maybe engineers from Eizo Nanao started to work for Toshiba or vice versa, or subcontracted help in design work or who knows what but its just kinda funny to me.

I have wanted to reach out to jomac and grant my self to try to grow my understandings a bit more but just dont have the time of day for that atm.

Just wondering if any of the Windy 2 owners have any spare parts? Looking for the monitor bracket/frame and a coin mech and mounting plate

I am always surprised when I see this thread still going.

I finally set aside my pb-7534 after doing a bunch of work to it and getting it to turn on. I could not figure out the issue with contrast it was having, neither subcontrast or contrast pots do anything. I got a picture that only shows some of the colors. I decided to set it aside and install a 2933 a friend of mines brought me from Japan last year. I had to rebuild it cause it was labeled junk and had the horizontal yoke connector traces burnt. After a full recap and repair of the horizontal yoke connector traces it seems to be working. I had it raised of a box of M&Ms, I did not want to cut and splice wires. A buddy that works construction will build me a platform this coming week for me to permanently mount the 2933 chassis. I was able to test both 15 and 31khz and both looked great.

 

[JohnRambo'sKnife]

That looks fantastic.

 

[cruzlink2]

On the original pb-7534 I am still curious what could have caused the contrast not to work like that. I might take it home when I have time to look for any broken traces around the area. It's weird that neither the subcontrast pot on the neckboard or the contrast one on the remote board do anything.

 

[cruzlink2]

Met one of my homies that works construction Tuesday night, he made me a permanent riser for the MS-2933 out of wood. I used some hex risers to secure the chassis to it.

Congrats, @cruzlink2 .it's amazing to have an working Windy 2 !

 

[Ziggy Cheetos Dust]

Thanks for the pics @cruzlink2. It looks like you found the best orientation. It’s like doing open heart surgery getting the chassis in and out without elbowing that neck.
