R&S SML01 Screen Lines
« on: January 02, 2019, 04:54:03 pm »
I've acquired an used SML01 for $90 at a swapfest. The guy I bought it from said the only thing that happened when you turned it on was the fan spun up. Well, after some poking around I noticed the cable running to the screen was kind of loose. After plugging it in the screen came up correctly, but has a couple of lines in. I've been trying to narrow down the problem, but I'm uncertain if the issues lies with the display itself, or something on the mainboard running the screen part. I've seen that you can buy new screen modules online, but they're like $100 and I wanted to narrow down the problem before I spent that kind of money...

Hitachi SP12N002 specs :     
http://www.panelook.com/SP12N002_KOE_4.8_LCM_overview_16707.html

256x64 pixels

Datasheet :
https://datasheet.octopart.com/SP12N002-Hitachi-datasheet-13295826.pdf

T6963C Equivalent,  you will be able to source the same t6963c 256x64 lcd  and adapt it,  now they have led backplane instead of CCFL

Oops  the 256x64 is not an standard size it seems ??  240x64 is very standard

256x64 lcd i've found :
http://www.mini-box.com/picoLCD-256x64-OEM
The pico lcd as a daughter board to be removed, the board is for usb pc display infos  etc...

This one seems right

The test could be made with an 240x64 with led backlight,  sure you will loose 16 pixels in height, but you would be sure it's the display and nothing else ??

good luck


OOOOOOOOOOOOH  a thread here  check this out:

But your lcd is working ... the supply lines should be okay ...  back to the lcd ...
