hi, I´m have the same issue about losing the shades with the bivert chip,can anyone help me? also my bivert chip is so tiny, I see a lot of pics with bigger chips, maybe there are another chips I can use. I did the backlight with the resistor and that´s OK, but contrast is low, handheld legend told me is working on a (no need to solder) chip, maybe I should wait before i break another DMG (allready broke one).

Needs pics of chip, location and nearby components.
IIRC, the common place for a bivert chip is near that 2x3 block of through holes, right? Grounding one of these will effectively remove two shades from the disply. I believe they are the screen data pins. Careful near that location.
I think maybe i replace the chip, because is so tiny, pics may not help because I cover the chip with hot glue (gun) to protect the solder points.
I´m looking for a bigger, cheaper, chip i can get in any store (argentina) to do this mod fawless.
thanks for the reply

that is the chip I use (was very tiny) and I follow this tutorial, check all the conections, but lost the shades
Have you asked on the handheld legend forums? He's normally pretty good about getting back to people.
I definitely need another chip, I accidently broke pin 6, is the second one, to tiny, to hard to solder, a bigger chip, the cheapest the better, thanks!
Pin 6 is an output, leave it hanging and choose another gate:
thanks for the advice, the pin that it´s broke it´s 7, wich is ground, maybe for that I lost the shades, can I use another?, the rest of the pins seems right
