Hello , Unfortunately a component seems to have burned out. It is located on the motherboard under the core board. See photo. Pumpkin won't or can't tell me about it. Since the component is probably a transistor, it has unfortunately burned out and the designation is illegible. Can anyone tell me about it or have a wiring diagram. The model is Pumpkin AA0505B-b01 Made 2020 06.15 Version 06.

hello
Please help me solve my brick unit, as the chinese seller does not want to help me.
I dont. know how to identify it , maybe you can help me. Also, i can't post links so please don.t be mad at me.
last year i bought an Android headunit for my Skoda. it is from Aliexpress, Auto Funrover Store...
It has OEM plug, internal CAN BUS decoder, MTK 8127, an was good price. But the software was awfull and they send me a lot of software versions, but no good.
So, to make it short :
- at some point, the unit did not work well with the CAN. wrong door open was showed on the screen, rear view screen appeared event if i set it to OFF, etc
- the seller send me an update for the MCU, i tried to update, but the unit got stuck at 40%.
So brick, no boot. They sent me a MCU chip, i replaced on the board. The unit worked awfull like before, but at least it worked.
they send me another update for the MCu, and of course, the update stopped at 40% and now the unit is brick again. No support from the seller.
i tried to update the MCU via SWIM with STLINK, but no go. The MCU chip is STM8S006C6T6 from ST and the version is MCU SM92D1.160428 V1.1-LC-B3
Please give an advice ! ask me any detail, i will post it here.
thank you
Hello there guys, i'm searching informations about this unit.
A friend of mine made some weird trouble with power cables, resulting in a not powering on unit. (Blowin' up fuse when powered)
I'm searching for schematics about this motherboard.
This unit il labeled as "AR6002B".
Here's the story:
(I'm quite confident in repairing notebook motherboards, so let's give it a try! )
No bad components after visual inspection, so let's go in deeper.
B+ (yellow) cable is shorted (making tests with protected PSU)
ANT, ILL and ACC are free and with no shorts.
The section i'm going to inspect is the primary filter and the 78D09, the ic near the smaller alu cap.
Do someone have informations about repairing this motherboard?
Thank you in advance
P.s. i cannot upload photos of the board due to minimum post count
Hi, in some cases with screen problems in px5 head units, could be bad contact from the main board with the heatsenk on the CPU.
Its fixed by just 2 screwes from One side, the other side its where is the contact pins. And where is the problem to, could have bad contact or not good aliment because a not perfect board alinement.
I used a special glue like epóxie, its rigid after done, What is it needed, and at same time it could come out if it os need.
Please looks até my pictures.
It worked for me

I have a Hizpo 9 inch head unit installed now for approx 3 weeks. It was working great and then for no reason the unit shutoff and I saw smoke come out of the dash momentarily. I keyed power off immediately and then switched the power back on and nothing. Thinking it was a wire or fuse I removed the dash bezel and checked the install for anything that could pinpoint what happened. All was good including the fuse. I then did a sniff test and could smell something burnt inside the unit. I took the back off the unit last night and noticed one of the circuit chip looks fried. Does anyone recognize what this is? Below are the specs of my unit from a pic I took right after I installed it and also added pics showing the board with the burnt "circuit".. If anyone has a schematic please share. Thanks.

Found it online YD1821B YD1821 SOP-16 SMD navigation motherboard chip
Can someone tell me what this element is and I can try to replace it. It is apparently burnt and the circuit board gives a short. As a last resort I will order a whole new board from here

You have the link to the unit and the seller...
Well... why not asking him?
