Question about T-Mobile MDA Pro Smartphone

2 Answers

MDA PRO The charging pot is loose and if left alone does not charge. Also it sometimes does not respond to sytlus touch which I think is due to screen alignment. The screen alignment takes ages before the handset can be used and yet, it does not work properly.

My screen doesn't respond on my viewty when I touch it, so I cannot access anything. Can I get this fixed? - Cheers, Debi

This can be fixed by purchasing a new digitizer.
Very low priced replacement. You can then have it replaced by a tech or replace it yourself.
Thanks for using fixya.

I cant get my mda to turn on i hold down the power button for a while but it wont turn on i charged it for 3 days and it still wont work what should i do?

Mda Vario's don't charge when turned off, heres what you do.
cut wire off a usb lead the small end strip the red and black wires, put the red wire onto the posative connection where the battery is it tells you what side is posative and negative on the battery, use black with negative and red with posative making sure that no wires touch the other metal strips in the phone, replace battery plug usb into computer and start up the mda and wait for it to boot. once turned on leave to charge as it will charge through the wires connected to the battery, after 10 to 15 minutes plug in the actuall charger and try to remove usb wires without taking battery out. if that is not possable it is ok as the battery should have enough power to start up once it starts leave to charge and always keep some charge in the phone.

My T-Mobile MDA won't turn on or take a charge, battery was low

I had the same problem, but got the idea to "jump start" the battery from Googling the problem. At night, I had turned off my MDA to charge the battery and then in the morning, couldn't revive it. I removed the battery from my MDA, and determined which battery terminal was positive (far end of one side) and negative (far end of the other side) by using a multi-meter. BTW: Battery was still @ 3.5V (okay…battery was still alive, if just barely). Then, I found a 5V DC charger (5W Max output = ~1A) from my bluetooth headset. I used one wire (CAT5E) and connected it to the negative side of the adapter (outer sleeve - again, verified by multi-meter) and another wire to connect to the positive tip of the adapter. I had to strip about 1/2-inch of the insulation off of the wire on the DC adapter side, and about 1/8-inch of the wire on the battery side. Plugged in the 5V DC charger and then I touched the negative wire to the negative battery terminal and held it there, while I touched the positive wire to the positive battery terminal for about 30-45 seconds. Put the battery back in the MDA, started it up, and now it's charging on the regular MDA AC Charger that came with the phone. Problem solved.

T-mobile Compact iii screen failure

Sometimes the SIM card will cause this problem. The first thing I'd do is ask T-mobile if they can diagnose this issue down to your SIM card and have it replaced. If that's what it is anyway.
How often do you turn it off? ( you should turn it off regularly, at night when it's charging or whenever ) Do you have a lot of stored info that you do not use? It could be corrupted, try erasing some things you don't use anymore. Just a couple things to try.

Touchscreen doesnt respond

Hi Your touch screen is part of your LCD and it was connected together thru a small thin cable and it is fragile. When this cable is bad or lost contact , your touch screen is disabled. Only way is to open the case and replace. The method to replace it was tricky. If you make a mistake, you can damage your LCD or scratch it. Please visit these sites for some information: 1) 2) (Store sell Touch Screen) 3) I hope these information will help you to find the solution for your MDA. Actually, I am repaired all phones and PDA too. If yo need for my help, you can email me at I am writing a lot instruction of how to repair or replace the housing and LCD/touchscreen or can be called digitizer. Good Luck. Regards, Joseph
