EEVblog #1202 - LCD Repair Redux
« on: April 18, 2019, 04:59:40 am »
The previous LCD repair didn't last very long. Redux time.
Installing a new 240x64 LCD module in the PM300 Power Analyser wasn't exactly a walk in the park.

Good follow up video.
The PSU I have works the same way, you can only adjust contrast after power on with the arrow keys. Which makes sense, if the contrast is completely off the screen isn't readable, making it hard to navigate menus. Just very hard to figure out the functionality without reading the manual.

It makes me wonder how many of us were asking 'I wonder if there is a software setting to adjust the contrast'?   I know I had that thought at some point early on in the video.

It would be interesting to see if removing the mod and adjusting contrast with the software setting would work...

Buydisplay also have the classic 240x64 for reasonable money.

With courier to oz it's almost the same price as digikey

You threw me for a minute there, couldn't figure out how I had missed this in the patreon cut.    After re-watching the new ending, all became clear.

"Beautiful. No pads lifted, thank you very much. I'm a professional!"

Can I use this a catchphrase?
