--- Quote from: 9aplus on November 06, 2015, 04:48:09 pm ---Over the time of approx 10 months my unit LCD developed delamination / deterioration See both up left and bottom corners, and switch off picture of left up, it is between LCD layers... Unit was stored over the summer in original bag within dark & dry and temperature was never more than 30-32 o C This is the same unit picture from FEB 2015. Unit is still good for use, but now looking for spare screen or whole broken unit with good LCD :-BROKE PS any lead on LCD type and producer is much appreciated :-+ --- End quote --- It is the gasket that sits between the LCD module and a transparent plastic panel that protects the screen. I have not fixed mine yet, but I took the front panel apart and I verified that is the black gasket. It should be easily fixable, no need to purchase a new LCD module. I have seen many units on eBay with the same issue. |

I have periodically at different levels of brightness blinking display. I had to find a reason. The culprit was the inverter. To eliminate the defect, it is necessary to solder the resistor of 1 mom-2 mom in parallel with the capacitor C20. (Between 4 and 5 pin BA9743A). |

--- Quote from: technogeeky on February 28, 2017, 10:19:40 pm ---Well, I forgot an important question. I just got my unit today, so before I do something stupid... * Is the power supply center-pin positive? Yes*. * I looked through this thread more carefully; it's 9-24V DC, somewhere between 3 and 5 amps; center-pin positive. --- End quote --- The DC plug is 5.5 x 2.5mm center positive. The most common plug size is 5.5 x 2.1 and it does not fit unless you push it very hard, which can break the DC jack. |

Has anyone had any luck using either the serial ports or gpio? I was hoping to get it to spit out useful data on the serial port. |
