Screen showing only blocks ?
|
Just finished my first ubitx v4 build and things are not working as expected...Thanks first of all for any and all help. My main symptom is that on power up the display is showing a string of blocks on the bottom row.. Somewhere about two thirds to the right is one blocking dimly blinking. A quick disconnect before something went poof and subsequently with longer power on no change was had. I then plugged some ear buds into and could here some birdies and other odd sounds etc. as? I turned the tuning control. Have any of you all had or know of what this problem is or points too. I know this isn't much info to go on but all support/help/advice is appreciated.

Did you try to adjust the pot on the back of the display board ? It only effects the screen and if too high you get blocks? and if too low nothing.

Well, the only pot I saw was on the board that the screen was actually plugged into. Tried end to end, no effect at any point. Hope i didn't mess things up worse.. Sill could here digital noise in ear phones as i tuned so maybe not all lost. I planed and have 3.5 screen on way, but would like to get this thing up and running before trying to install new soft/hardware. One other observation is that the row of blocks or on the bottom row of screen only, also the 5 volt regulator got to hot to hold finger on in less that a minute or two,,, something amiss here me thanks.... what say you - someone - anybody - any ????? :)

I have also now linked to the detailed assembly instructions for the v3 board. On 19/07/18 9:59 AM, Dexter N Muir wrote:
This really ought to be prominent on the website and included with kit: "On power-up, screen may be either blank or showing blocks. Adjust Raduino's contrast pot for clarity of text". --
