@RIKKO14 said in MMM-GoogleMapsTraffic : black screen by copying the code in config.js:

width: ‘300px’

I think you missed a comma at the end of that line.

@cowboysdude The module works with a weather.io API. The Waether Underground API is not an issue in this case.

Also in my case it stopped working. Has anybody figured out yet why this is happening?

Maybe try a MOSFET to get 3.3V. However, I am not very confident that would work. I don’t understand why it didn’t work when you combined the pins 28 and 30 with 2 and 3.
What happens when you only put 3.3V on pin 30, leaving 28 (VDD) disconnected? And what happens if you reverse it (28 = 3.3V, 30 = 0V)?

Maybe somebody else with more experiences with LCDs could join the conversation?

@Daiki Do you have an extra LED driver for LCDs? You could take the connections from there. Kinda like in this picture:

I am not really sure how correct I am but it looks to me that those pins are for the LED backlight of the LCD panel. As far as I can see the LCD controller board doesn’t have an in-build LED driver. VDD and V(LED_EN) are both 3.3V. Maybe combine those pins with pin 2 and 3 and see what happens.

Of course there is always a risk of frying your panel so I am not taking any responsibility! It’s just a suggestion of what you could try to do. Please report once you got it to work.

This is incredibly impressive!

Do you have the LVDS cable? A 6bit-1CH LVDS has different pin population that for instance a 8bit-2CH. Vcc and GND are at different locations and a wrong cable could potentially fry your LCD.

I am on my phone without my glasses, so I can’t see very well but on the imgur picture it looks like a 8bit-2CH cable while a 1366 resolution seems more like 6bit-1CH (just a guess from my little experience with LCD panels, don’t take it as a fact).

Have you tried to hook it back up to the old laptop to see if it’s still working?

Also, have you flashed the right firmware for the controller board?

@sw76 I am sorry, I couldn’t find a datasheet for that screen. It’s generally tough to find datasheets for TV displays. Had the same problem when I build my mirror. In the end I found a free broken computer screen with a working LCD panel. Maybe that’s a better option for you.

Also, I assume the blue tint is a problem with the panel itself and not a problem with the controller board. Maybe it’s just the cable, though. Check both end for continuity.

Good luck with your project!

You can find universal LCD controller boards for cheap on eBay or AliExpress. Try to find the datasheet and if the LCD has a LVDS interface I’ll help finding the best controller board. A quick Google search didn’t show anything useful. Maybe post pictures of the LCD panel with all labels visible.
