can someone with this board please take a photo or give me the text of the EC1 componat as mine has burn out

Looks like the same diode as E1; 107J 73844jellybelly wrote:can someone with this board please take a photo or give me the text of the EC1 componat as mine has burn out

Re: Full VGA resolution (640x480) 3.5" display, composite in
I'm really interested in how you wired up the gert adapter to the pi zero and the vga ... and what usb sound card are you using. are you using powerboost and camble safe shutdown?noebl1 wrote:Just an update... I ended up with Helder's AIO 2.2 board using the VGA GERT, USB Sound Card and USB WIfi adapter. I haven't finished with all the GPIO testing, but if math is right, should have enough GPIO left over for Camble's shutdown board. Very happy with the VGA video
Important to note selection of Wifi USB device not only important for compatibility, but also for power usage. Between the 640x480 display, VGA GERT, USB Sound card and Wifi board, some of the Wifi adapters I used actually were pushing the Adafruit 1000C board and I was having issues.
thanks

I'm using this cheap sound card; https://www.amazon.com/gp/product/B00IR ... UTF8&psc=1 . I can see about taking some pics of the mess tonight. I am using the Powerboost 1000c, and I also have the Camble safe shutdown, but not yet wired in (though I still have GPIO left.) To keep potential for noise down (may be paranoid), I soldered the GERT VGA direct to the Pi Zero thru a header. Once I get the GPIO sorted out for the shutdown, will clip all the unused pins flush.marcushg wrote: I'm really interested in how you wired up the gert adapter to the pi zero and the vga ... and what usb sound card are you using. are you using powerboost and camble safe shutdown?

I'm debugging a couple of issues so haven't finished yet:
* With the sound card and higher resolution display, it pushes the power usage pretty close to the limits of the Powerboost
* The sound output on the speaker is way too low, however headphone output is very loud thru the Helder's All in One board. Read may need to adjust some of the resistors to resolve this.

Re: Full VGA resolution (640x480) 3.5" display, composite in
So I have this screen but am unable to get a picture
It's completely dark, but I have the led red on the board. When I press the menu button this won't come up either so I am unable to select the input
Any help?

My guess since you get no menu, it's not the video feed (menu shows up regardless.)jellybelly wrote:So I have this screen but am unable to get a picture

- Check ribbon cable connection and polarity
- Bad LCD
- Bad display board
Sorry

ribbon cable look fine holding it up to the light
the polarity is right as per the symbols on the rear
the board im not sure as the capacitor was burn out when i recieved it so i replaced with the same one and i get a light on the button board now, but i suppose i will never know what damage has been done when the capactior was fried
lcd not sure how you can test it without a working driver board really
hmmm just about sums my week up really

Ouch Not the best solution, but you can buy the controller without the LCD:jellybelly wrote:ribbon cable look fine holding it up to the light
