Display screen black not responding to joystick

[Jbowen590]

The display screen started out looking glitchy but I was still about to go through all the menues. Then it cleared the picture but wouldn't change from it's home screen. Now it's completely black and will not respond to any joystick function. Tried resetting and reloading code no change. Please help.

Private message you?

[Jbowen590]

Says I'm not allowed to use private messaging. Do I need to have a certain amount of post to use this feature?

[lnevo]

You need one more...

[Jbowen590]

I figured it would be 5 thanks for the info. Let's see if it works.

I'm having the same issue, my screen went blank last night and now it won't turn back on. I've reset the controller, the green power light comes on but no LCD screen

[rimai]

Is the controller still turn on/off relays?

[c_wick]

No, it's no longer running its program

[rimai]

Can you upload codes to it?

[c_wick]

I tried but nothing happen. The arduino software looked to be uploading, it said done uploading but the controller didn't flash, it just stays constant green light on the power

[rimai]

Did you look for any sign of water damage?

[c_wick]

I don't see any water damage but there was a rattling sound inside so I opened it up and one of the metal brackets that the power cable screws in to to keep it in place was jostling about. Do you think that could have shorted sometime on the board?

[c_wick]

Roberto, i'm wondering if I should purchase a new head unit board or if I should get a new LCD display? Would the LCD display being out affect my lights not turning on, or would that be controlled by the board?

[rimai]

If the unit is not controlling anything and it is not accepting code upload, it is most likely the head unit board.
If it was just the screen, the controller would still be working.

[c_wick]

Ok thanks Roberto I'm going to order a new board then. Always appreciate the help.

[c_wick]

One last question, if I upgrade to the head unit plus is there any change as far as wires and cables to what I have now or is it just more memory? I have the gen 1 LCD display so would that still be compatible?

[rimai]

Yes, screen is compatible.
It's a swap replacement with nothing to be changed, except the head unit board.

[Jbowen590]

Installed the new screen and this is what it's doing.

Any suggestions?

[rimai]

Yeah, your board is setup to use the gen3 screen.
Use this code right above ReefAngel.Init();

Code: Select all

  InternalMemory.LCDID_write(255);

[Jbowen590]

// This must be the first line
InternalMemory.LCDID_write(255);
ReefAngel.Init(); //Initialize controller
ReefAngel.AddStandardMenu(); // Add Standard Menu

this is what my code looks like and screen hasn't changed.

[rimai]

I'm sorry man....
I made a mistake....
Gen 3 screens need this:

Code: Select all

  InternalMemory.LCDID_write(0);

[Jbowen590]

Thanks that did the trick. Working great now.
