Hi I bought Pipo m3 on pandawill.com last Sept 28.. and I received it Oct 11... On the first time that i boot the tablet I saw the deadpixel and 3days later.. I cant even navigate it using its touchscreen...
Anyone can help me regarding this problem? I dont have enough money to send it back to their company cause here in our country the customs will try to force you to pay more for them.. they want me to pay them almost $90 just for sending the tablet to china.. I think i didnt deserve this problem and expenses that I'm experiencing right now.. I just want this tablet work fine..

I will appreciate any inputs that could help me to fix this tablet.. I'm from the Philippines by the way...

Hi Gerwin,

Which firmware are you running? The latest one in my main M3 thread dated 11th October fixes a number of issues. If you aren't already running this it would be worth trying to see if it helps with touchscreen issues.

Dead pixels you will have to live with if you cannot return the tablet.

I don't know what firmware version installed on the tablet.. I'm losing my faith that this tablet can be fix.. I don't know what mainboard version that comes with this tablet so I dont have the guts to flash its firmware and upgrade it.. I'm not also particular on flashing androids cause I'm scared on bricking it.. and also it will lose the warranty so I dont usually flash/root my android devices.. this is the only time that I dont have any choice.. I can't send it back I guess so maybe I just wait if they can give me any refund because of the damage that they cause to me.. this is worst case that I invested my money and time on a wrong gadget... it really sucks... :(

Gerwin, yes, you have an old board. Also it seems you have the latest firmware already flashed (from Aug 30)...

Wow, good luck.

What shipping company actually sent it to you. Because on the first image I see, Fedex, DHL and a few other couriers. Also, on the one tape, there is written: "Received in BAD ORDER". Which is really weird. :p

I had this problem too and I could not find the solution on the Internet.
Fortunately, I've bought the tablet on Spemall, so they made the manufacturer, Pipo, to give the solution of this problem. The problem is hardware, so it is necessary to open the tablet.
The original solution was in Chinese, so I made my own in English with better picture. It is connected to the post.

HI NicolasG,

Thanks for the information, very useful. Someone I know describes exactly this problem with his M3 so I will try and fix it for him.

How did you open the M3?

Thanks
Jez

Tablet_Collector,
It is rather easy to open. I used special plastic tools for this, but you can use mediators or obsolete credit card. I started opening from the upper right corner of the tablet, when you rotate it with back panel to yourself. The edge with slots and connectors should be the last one to open. The plastic is rather soft, so you won't break anything if you'll careful.
vitiss,
yes it will. We on 4pda already have the same solutions for Pipo M2 and Hyundai Rock X with the exactly the same problem.

Well, i have tried, and the result is here: My diod touch screen still doesnt work. I have measured the voltage and it was 4.6v before inserting the diod. Do you think that i did something wrong?

vitiss,
The voltage should be around 15V when the screen is on. Seems, like you measured it when the screen was off. As far as I remember, I had about the same voltage then. May be you soldered the diode with the wrong polarity. It won't work then. Just try to change the polarity or use another diode. It seems that Pipo M2 and Pipo M3 use exactly the same motherboard and people on 4pda already managed to repair the M2 touchscreen with this method also.

Hi
I have the same problem - not working touch screen, but mine voltage is only 4.7 while screen is on. It is pipo m2. Maybe you can contact the seller again, so they would tell you what to replace in this case?
