How To Repair Iview Ultima

Hi,
My IVIEW ULTIMA EM-H8316-V2.0 motherboard is faulty so I'm searching for the repair & services guide with electronics schematics to run across how to set up it. I'd like to measure the different chips voltage and so if someone could help me detect and download the IVIEW ULTIMA EM-H8316-V2.0 service manual it would be not bad.
My computer won't turn on anymore, no led when I plug the charger, it stopped suddenly while I was working on it.

Thanks a lot for your assistance.

Hello and Welcome to the Laptop & Desktop PC Motherboards Repair Forum

Reddit is your friend. I institute the guide a few days ago posted by a redditor at that place, hither is the direct link to his blog. Hope it helps you fix your motherboard/laptop as information technology helped me gear up mine every bit I take the same one.

IVIEW ULTIMA EM-H8316-V2.0 maintenance guide (pdf & fz)

Best of luck

Edit : Information technology's free I just had to complete a quick survey to get the guide then the PDF appeared + the fz files (boardview files listing all the components on the motherboard'due south pcb), whereas all the others sources I found online were asking for $$ hither y'all tin can only download the guide right afterward the survey and you're good to get.

Hi I also accept this IVIEW ULTIMA EM-H8316-V2.0 and I downloaded the services guide to a higher place could you lot please tell me how to cheque my motherboard and what to expect outset exactly? I'm a bit lost when I expect at all the measuring points and schematics in the transmission. Cheers

You can start by checking the charging connector soldered on the lath yous should read around 19v, so cheque the two entry mosfets most this connector, look for a short circuit by doing a continuity examination with a multimeter.
D=Drain pin v-vi-7-8
S=Source Pin 1-2-3
G=Gate Pin4

Downloaded the IVIEW ULTIMA EM-H8316-V2.0 maintenance guide above, couldn't find information technology anywhere else for free, thanks for the download link yous rock bro.

How-do-you-do, I get 3v on the kickoff pin of the bios flake, and 0v on the pivot viii is that normal?
According to the schematics diagram in the transmission and datasheets, I should have 1.8v there, right?
How to cheque the processor? Is my IVIEW ULTIMA EM-H8316-V2.0 completely dead?
My 3v 5v regulator seems fine though since I tested the voltages and ground. emoji scratching head

I doubtable my IVIEW ULTIMA EM-H8316-V2.0 has a short circuit somewhere cause it doesn't commencement anymore but I am totally noob and don't know what to begin with, the motherboard looks like a puzzle to me...

I have a multimeter so I tin attempt to fix it if information technology's not too complicated, how can I repair my MB please? I saw you lot tin can buy mosfets or capacitors and resistances online, chips besides like the super IO i, and so why not try to repair my computer myself...

Don't jump into the repair volume and chip level correct away. Depending on the problem information technology won't be the aforementioned approach. Does your laptop have any issue with the disply, or the power? Outset with the basics by measuring the voltage at all the measuring points showed in the repair guide, and come dorsum with all the measures so nosotros can help you lot prepare your IVIEW ULTIMA EM-H8316-V2.0.

It'south important to proceed step by step instead of speedily replace parts like RAM or graphics chip or even the processor, start thing kickoff check if your charger is working. As simple every bit that. Also check your bombardment.

And so you will proceed and bank check the circuitry : coils, mosfets, capacitors, inductors, etc.

If you are a full beginner in electronics better have your computer to a repair shop to avoid causing more damage to it, even if it costs you a trivial bit. They can solder and desolder parts very apace without taking any risk for the rest of the components.
They can besides merely check your IVIEW ULTIMA EM-H8316-V2.0 and tell you what part is causing the problem, then it will be up to you to replace it if you prefer doing information technology yourself (a slice of advice when soldering, always use flux or rosin).

I think I damaged my notebook while flashing the bios, is such a problem even possible? I tried booting from an USB bulldoze with no luck it failed.
I downloaded the IVIEW ULTIMA EM-H8316-V2.0 repair guide it will aid me make the right diagnosis, well I promise so. I guess I accept some work to do now.

Here are the top 5 things I always exercise to troubleshoot your faulty MB:

Check the charging connector. Most of the trouble comes from hither. Test information technology with a multimeter to meet if you become the +Vin (DC +19.5v) at its pins.
Locate all the coils on the board and check them for continuity to the ground. (multimeter in diode mode). These components are the power supplies of each office of the board, if one power rail is down then information technology can prevent the laptop from working.
Check all the mosfets on the pcb. At that place are around a dozen, a lot of computers breakdowns come from a short circuit in a transistor. By and large the ii primary ones after the charging port, they are very encline to shorts due to their abiding solicitations.
Use isopropyl alcohol to locate overheating components. Heat makes it evaporate quicker when put on shorted parts that are very hot.
Finally utilize a voltmeter to check the voltage on components nowadays on the 3v/5v rails, if you don't go the correct voltage there then the problem is probably due to the voltage regulating chip, or a failure from a capacitor.

@AugustPaganini, doesn't make much sense to me but ok :)
