Panasonic 5" monochrome monitor WV-5200BU
A friend cleaning out his broadcast/editing stuff gave me a few of these Panasonic 5" monochrome monitors, model WV-5200BU.
I don't have a pic on my website to show here, but there are some shown here: https://www.visualalchemy.tv/product_pdfs/2907_va.pdf https://www.ebay.com/sch/i.html?camp...ic%20WV-5200BU Does anyone else use this sort of monitor? One works well, and I'm looking for a schematic for them, hoping to get all of them going. They were headed for the scrap pile so I saved them. These have a linear power supply and the raw DC looks OK. They are old but the CRTs look good, no burns. I know these are not really collectible, but they are handy and of good so why not fix them up and enjoy them!

These are usually easy without a schematic. We rarely had
one due to cost & wait time. Having a worker helps also. As a general comment for all , almost all TV's are broken down in blocks. Example is: Power supply 800 IF 100 Vert 400 Hoz /HV 500 etc. etc ALl parts with 400 numbers will be in the vert. So IC401, C408, R420 etc are vert related. This is an example & will vary among MFR's 73 Zeno LFOD ! |

Some of the most reliable b/w monitors ever made. I have two, not sure the mod numbers, but the later one is circa 1990 and uses a Samsung Korea CRT. The orig Panasonic version with their own tube has razor sharp and very bright pix with good detail. They are fun to work on since the chassis is not crowded at all and they kept parts counts down in the spirit of 24-7 reliability. Hell I think mine might be entirely discrete construction.
I use my "better one" with a USB circuit camera/magnifier which comes in handy all the time. Had to buy a cheap USB>RCA adapter and then place an RCA to BNC barrel on it, but the video is clear as anything. |

They are good little monitors with a bandwidth that goes beyond 10 MHz. Electrolytics and solder joints are the only big issues in these, only once have I had a bad CRT. Early ones use SO239 input jacks, later was BNC around the mid 80s
