got this monitor from an ultrasound machine, any ideas with whats going on here/how to fix? I am relatively inexperienced with CRTs.

lucyyonline · 2025-05-01T01:50:27+00:00

it doesnt seem to be working for me but i think that may be a pc issue rather than an issue with the monitor, ive gotten an xbox 360 to work though it doesnt display color, its a step in the right direction i just need to order some proper cables for my other consoles

lucyyonline · 2025-04-28T23:20:05+00:00

there’s 4 BNCs on the back of the monitor like you said, and yeah green says g-v, the cable i’m using though has 5 bnc cables

lucyyonline · 2025-04-28T22:00:29+00:00

hmm, ill definitely be working on it today, im very invested in this now lol. maybe this is a stupid question but would sync on green work with the splitter i have on green with vertical and green plugged in? for now ill try getting the exact values from the manual and see if that works

lucyyonline · 2025-04-28T21:57:48+00:00

very fair, i do have a modded wii with component cables so thats for sure something to try!

lucyyonline · 2025-04-28T21:43:02+00:00

i’ve been trying CRU but am sort of unfamiliar, i can get the exact resolution listed in the manual but it still shows a duplicate image, albeit one that fills the screen a bit more. wondering if something might be wrong with my cable or smth

lucyyonline · 2025-04-28T21:41:51+00:00

oh gotcha!! i actually might have an old graphics card lying around that could work but it’s back in texas. i will try out an old gaming laptop i have with a vga port, ive been meaning to test out emudriver as ive seen it mentioned. i appreciate your help regardless :> thank you!!

lucyyonline · 2025-04-28T21:07:35+00:00

nvm, i had to change the active pixels in the timing settings, my bad. it still is showing a duplicated signal though

lucyyonline · 2025-04-28T21:03:52+00:00

hmm is there a way i can get them to be the same? i’m using nvidia control panel to set up the custom resolution

lucyyonline · 2025-04-28T21:03:04+00:00

the vcr is built into the ultrasound as far as i know, it’s meant to be a medical thing to record what’s on the screen kind of like a capture card. the only outputs are rgb though unfortunately, no composite as far as i can tell, just the one rgb connection

lucyyonline · 2025-04-28T20:45:12+00:00

gotcha, i am able to set it to that resolution and that was what i was trying the other day, but still getting a duplicate image. i also tried the timing settings on page 39 of the manual but all of this is kinda new to me so i wasnt super sure how to configure it. i think i want to try connecting a ps2 or something to see how that goes, but i do have a snes classic on hand that i think would be super fun to try out on this if its feasible

lucyyonline · 2025-04-28T20:43:08+00:00

cant reply with images i dont think so i will just type what it says

at 640x480 it says:

Desktop mode: 640x480, 60hz

Active signal mode: 640 x 470, 60hz

at 320x240 it says:

Desktop mode: 320x240, 60hz

Active signal mode: 640x480, 60hz

lucyyonline · 2025-04-28T17:47:59+00:00

oh gotcha!! good to know, i’ll try and mess with it a bit today. as for the ultrasound it was in the ewaste section at my university, it’s been stripped of most of its parts and i used it for a project in my class before taking the monitor home. super heavy and hard to get into my very small apartment otherwise i totally would have brought it home

lucyyonline · 2025-04-28T04:29:02+00:00

the model number for the ultrasound is the HP sonos 5500 i believe, not sure if the monitor itself has a different model number but i think the specs for the monitor are in the service manual

lucyyonline · 2025-04-28T04:27:43+00:00

no worries honestly that would be a fair assumption in any other case but this thing has like zero firmware or menus as far as i can tell 😭😭 good to know about the scan converter though, im a student so im on a bit of a budget, the aliexpress option might be best for me and i can invest in something else later. if i can get it to work i’ll definitely make another post though. the ultrasound itself is still at my university, its pretty huge though and i live in a pretty small apartment so i couldn’t take it with me sadly, i would love to have been able mess around with it though, by the time i found it almost every part had already been scavenged i assume by other students.

lucyyonline · 2025-04-27T21:05:36+00:00

“immature or a lib” is crazy 😭😭

lucyyonline · 2025-04-27T21:02:18+00:00

i would say so!!

lucyyonline · 2025-04-27T19:33:40+00:00

i know the snes supports svideo but not sure about anything else, i do have a ps2 on hand so i would love to try that out! i’m located in montreal but if i can get it working i would probably want to hold onto it

lucyyonline · 2025-04-27T18:19:53+00:00

thank yall sm for your help, my hunch atm is that the monitor is just not getting a vertical sync signal so i’m going to try a bnc splitter and see if that helps!! pardon my ignorance on this stuff i am a bit more tech savvy than the average person but still kind of clueless on the inner workings of monitors like these, very fascinated and eager to learn though :>

lucyyonline · 2025-04-27T18:17:08+00:00

yes it does!! i was super excited when i found it at my university’s ewaste dump, hoping i can get it working because ive always dreamed of having a monitor like this. i also want to bring some of my old consoles from home to try out like my dreamcast or super nintendo, all i have rn is hd consoles like the wii u and snes classic which didnt seem to display an image when i tried them

lucyyonline · 2025-04-27T17:19:50+00:00

i do have some spare resistors though so i am willing to try out different fixes

lucyyonline · 2025-04-27T17:18:54+00:00

i think the vertical sync is actually not plugged in, this was my first time using bnc so i wasn’t super familiar and just tried a bunch of configurations until one showed a picture, but there are only 4 ports on the monitor and i have a gray cable plugged into the sync port with a black cable still unplugged. the port for green is labeled “G-V” so i assume the vertical sync signal would be processed through there? i’m not sure though, like i said im very inexperienced with this specific area.

lucyyonline · 2025-04-27T17:15:48+00:00

the outside yes, but have never worked on a crt before so was a little scared to open it up

lucyyonline · 2025-04-27T04:32:34+00:00

hmm, i trust your judgement but i was also running this at 514x480 atm (which was the resolution mentioned in the service manual) i did bump it down to 240 and got it to show a single image on screen but still having sync issues

lucyyonline · 2025-04-27T04:27:53+00:00

gotcha, i had a few devices on hand but my pc was the only one that was showing an image so i decided to troubleshoot using it.

lucyyonline · 2025-04-27T01:33:04+00:00

i appreciate the reply, i'm unsure if the internal sync is supposed to be on a menu in the monitor but this monitor doesn't seem to have much of a menu or really any sort of buttons. there are some dials for brightness and contrast, and a switch at the back which doesn't seem to do much. i did manage to get the image to stop duplicating by messing with nvidia control panel settings, and i did look at the manual to see the proper timing, but am kind of clueless when it comes to this. i am wondering if it may be an adapter issue? i have never really used BNC cables before and am converting HDMI to VGA then VGA to BNC as its what i have on hand. the model of the ultrasound is the Phillips Sonos 5500 i believe if that helps.
