Reflowed strategically : didn't work Reflowed with my hot air station the entire B board : worked ! Thanks ! (I got my first PVM 2 days ago, and this one today, both are now calibrated and I fixed the b&w issue on the composite, I feel like a fucking champion ! Thanks again mate, 100% of my knowledge came from your videos and cherry on top : I didn't get shocked !!!! Youhou !!!)
Search your are for any recycling companies and give them a call to see if the recycle any specialty Monitors for similar equipment for re-sale. Also some areas have government auction sites that will auction off AV and other similar equipment from time to time. Happy hunting.
Thanks for the video. I've been looking for information about my PVM-8044Q's. One works fine and the other is kind of doing this same thing. I'll have to give this a shot.
I have a little 8045q that I pack around due to its portability. The picture is fantastic due to its 450 tvl, a nice step up from the 250 tvl on this monitor. Its just enough to where you can barely see the scanline effect if your leaning in and peeping.
I also have a 8042q, Its has 450 tvLines. I had to do this same repair to it and it worked. I'll show both of them hooked up in a video towards the end of the week.
I had PVM-9041QM, and exactly the same problem with it, randomly lose color. I took it to repair, after which I sold it, and then I bought B&O MX7000 CRT TV.
Got my 8041Q working again! Thank you! Only problem is that there’s some discoloration in the top right corner. Any suggestions for a course of action?
Do you mind sharing which capacitors usually go bad in the power supply board? I have this monitor and I'm having issues (and because of the nature of the issue, got told it's very likely a bad cap in that board).
Great video, i have a Sony Pvm 1442Q ...tried to plug my snes mini over with a chinese mini hdmi to the Video In but i got black and white colors...what can i do?
Hi, I have a Sony 2054 QM PVM that only has color when connecting an NTSC console with composite. If I connect a PAL console, the image is black and white. What could be the problem and could someone, with a little soldering skills and a heat gun, fix it?
I have a PVM-8040 that will only display in monochrome. I know it is a slightly different problem (intermittent color loss in this video's example vs. permanent in my case), but will this re-soldering process work to restore color on any PVM with color problems?
I have a pvm 9040 with the same problem, do you know if the board and problem area would be in the same place? I'm new to this kind of stuff and really dont want to mess up my tv lol
Thanks for the tip, definitely going to keep this in mind. Do you have a video adjusting the deflection on one of these? I have an 8045 I need to overscan horizontally.
I've got the same monitor with balck and white issue only on composite video. RGB is working with no issues. Do you have any ideia why that's happening? Thanks a lot for all your videos =)
He didn't repair it just touched up some joints on a through hole plate boards that rarly if ever suffers from dry joints, I've certainly never seen dry joints on the board he works on, only ever seem them on tube base, psu and back connection panel they all suffer as single sided, through hole plated boards rarely go dry jointed, repaired literally thousands of these, check my channel out the proper repair is 2 x trimming capacitors on colour board used in colour circuit, 1 trim cap is for pal, other is for ntsc, change both, I've even got the sony part number for the part in the video, the older pre 1997 versions had orange body with silver cross head trim bits and they are crap, post 1997 sony switched and used "mura" brand and they never fail, repair engineer of 24 years working on these babys.
Retro Tech, thanks for the video, now currently working on my 1996 PVM 8041Q Trinitron, sadly since I'm not in the US anymore it is impossible to send it to you for repair, is it ok to send you a short e-mail with my problem? Thanks in advance.
Nice work as usual Steve. Looks pretty complicated on my end bro. But great for guys like yourself to have the knowledge to do so bro. 8*) Well done Steve. Keep it up. 8^) Anthony...
Thanks Anthony. I'm glad to finally gets these things working again. I pretty much sat this monitor on a shelf for over 2 years and never really messed with it since the colors would go out. I got two little 8 inch ones like this and I'm going to make a cool rack system with them, at least I hope to.
I don’t understand how it can only have 250 lines of resolution or how that can be “almost Hi-Def.” Standard-Def is 480-525 interlaced lines. Hi-Def is 720-1080 lines. Enhanced-Def is anything in between (480p, 600p, etc). If this tube doesn’t even have 480 lines then even 240p should suffer. Since 240p is kind of a 480i hack I don’t see how this could be a native 240p display which downsamples 480i or something weird like that.
These CRT's resolution is stated in terms of the number of horizontal lines across the screen. The higher the line count, generally means a clearer and sharper picture on the display. Digital video signals are not processed in this same manner as the 240p and 480i analogue video signals so the technology to display them properly differs considerably. This PVM monitor will process whatever 240p or 480i video signal you can input into it without any real screen scaling or processing, meaning it won't manipulate the true video image much. When I stated that the picture looked high def, I was referring to the screen look from the naked eye.
Don't think of CRTs in terms of pixels. 250 TV lines means there are 250 horizontal cells per line for the beam to hit, but that doesn't really relate to the input resolution. The monitor can display any resolution which fits into ~15kHz of horizontal scan and ~60Hz of vertical scan. 320x240 works just as well as 140x192.
Great information, well presented, good editing and camera work. The internet is awesome.
📺 Thanks! The internet is awesome.
Hear, hear! All in agreement, good Sirs.
The Internet is indeed, awesome.
Reflowed strategically : didn't work
Reflowed with my hot air station the entire B board : worked !

“CRT Recycling Facility?” Where do I find such a magical place?!

Thanks for the tip, I just fixed a 9041QM with this method, reflowing the main IC and the board connectors
Thanks for the video. I've been looking for information about my PVM-8044Q's. One works fine and the other is kind of doing this same thing. I'll have to give this a shot.
Thanks and give it a try. I fixed 2 in one day with this same method. Just a bunch of cold solder joints on them. Good luck!
Beautiful little monitor, getting hard to find these days. Sure has that wonderful retro look, love to find one and set it up for a gaming screen.
Picking up the same exact model for $30 this weekend. Can't wait to try it out. Will be hooking up my fat ps2 to it.

@@kennylauderdale_en Yeah. Even tho I have a 20L5, I still keep it around due to the picture quality and how portable those things are.
I also have a 8042q, Its has 450 tvLines. I had to do this same repair to it and it worked. I'll show both of them hooked up in a video towards the end of the week.

Convergence strips
Would you guys make a video about adjusting the geometry for this specific unit?
Do you mind sharing which capacitors usually go bad in the power supply board? I have this monitor and I'm having issues (and because of the nature of the issue, got told it's very likely a bad cap in that board).
Great job steve.
Thanks Kelly!
I use hairdryer to blow on the front right hand side of the PVM for 2 minutes :D I know I know ... but hey , it works
OMG (:0

I don't, I've only make color videos on this one, but it's easy to adjust using the pots on the board with the Flyback Transformer.
What cables do you use?
My PVM 14L3 turns black and white with composite at 60 hz but not 50 hz. Does not happen with rgb. Is there something wrong or is it normal?
I have a sony 4080 pvm, the lower right side has a purple tint, how can I fix that ?
does this also work for the 8044q?
I've got the same monitor with balck and white issue only on composite video. RGB is working with no issues. Do you have any ideia why that's happening? Thanks a lot for all your videos =)
I’m not convinced we actually witnessed a repair being carried out.
He didn't repair it just touched up some joints on a through hole plate boards that rarly if ever suffers from dry joints, I've certainly never seen dry joints on the board he works on, only ever seem them on tube base, psu and back connection panel they all suffer as single sided, through hole plated boards rarely go dry jointed, repaired literally thousands of these, check my channel out the proper repair is 2 x trimming capacitors on colour board used in colour circuit, 1 trim cap is for pal, other is for ntsc, change both, I've even got the sony part number for the part in the video, the older pre 1997 versions had orange body with silver cross head trim bits and they are crap, post 1997 sony switched and used "mura" brand and they never fail, repair engineer of 24 years working on these babys.
hi there, just wondered, is it OK to flip a BVM PVM or XM29 to be standing up tall for a vertical shmup
Yes, but not while it's powered on. I made a detailed video on this last month. ua-cam.com/video/Dyd-rfSyA2Y/v-deo.html
is it still working after reflowing? I have a 8042q on the way that only shows black and white hoping i can fix it up
So, there no risk of getting electrocuted while reflowing? I see that you didn't disconnect the board
Retro Tech, thanks for the video, now currently working on my 1996 PVM 8041Q Trinitron, sadly since I'm not in the US anymore it is impossible to send it to you for repair, is it ok to send you a short e-mail with my problem?

Retro Tech!! Do you fix toilets on here?
Do you have a toilet with a CRT built into it?
Toilets are more retro, and that would be one heavy toilet! haha
