Sony PVM-9040 Triplets: Trim Pots Fix B&W Issue

Wish me luck folks! #CRT #retro #RETROGAMING What do you think of these? @usa_retro

New @Buyee arrival today. I got these 3 nice 9" PVMs. Sadly not all went well and I had issues with customs. More o this and their state below. 🧵👇#RETROGAMING #CRT

Customs wanted me to justify the price, even though I supplied all relevant documents. Not being able to fleece me on that they then decided to flag these for physical control and hold them for a week. More fees. Box arrived beat up no expanding foam, never happened before.

If I had to take a guess, I'd say Buyee packed them with expandable foam as usual but customs removed it and chucked it out after "inspection". With physical control, they fleeced me for these 2 BS additional fees.

When I got the box from the delivery man I could tell the monitors were just rolling around inside the box. Fortunately, nothing major broke but one of the outer shells has a pretty big dent on it. It stretches outwards if you unscrew the screws on the case. Thanks @AUT_TRIB_ADUA

As for their condition, the tubes seem fine. The one I opened up didn't even have a spec of dust but they all have colour issues. Which is a known issue that is fixable by replacing some potentiometers. You can check out @usa_retro's YouTube videos on the fix.

I was a bit sceptical about these given they are only 250TVL but I've got to say the picture is actually quite nice. #Sony did not disappoint. #Nintendo #N64 #SuperMario

And so begins the journey of restoring the 3 Sony PVM-9040 that I recently acquired. Quiet late afternoon recap of the PSUs. No bulging caps this time. #CRT #repair #restoration #PVM #Sony

Restoration chapter 2. Replacing the trim potentiometers and applying the needed ceramic capacitor. With this, colour is now restored. Testing out the work with some #LegendofZelda Ocarina of Time. #CRT #repair #restoration #PVM #RETROGAMING #Nintendo #Sony

Let's play a game. These are all 9" Sony monitors using an S-video source, 3 are 250TVL PVMs and 1 is a 450TVL BVM. Can you guess which is the BVM? Individual pics below. 🧵👇 #RETROGAMING #Nintendo #N64 #Sony #CRT #BVM #PVM

Another day, a couple of more recaps. This time, a🧵on the deflection boards on my 3 #Sony PVM-9040. Having previously recapped the PSUs, fixed the color issue and reflowed the neck PCB. This is the final bit of maintenance. Pictures of monitor #1. #PVM #CRT #repair #restoration

Finally, some test shots playing Super #Mario 64 via S-video. #RETROGAMING #Nintendo #N64 #PVM #CRT

And also some test shots playing World Driver Championship, first pair of shots is of hi-res mode and the second pair of shots is of normal res mode. #RETROGAMING #Nintendo #N64 #PVM #CRT

And lastly a memento to the corpses of fallen electrolytics. 51 of them to be exact. #Sony #PVM #CRT #repair #restoration
