Samsung Galaxy Tab 3 and Tab 4 8.0 models are still common on repair benches across Pakistan, and the 8767-64 power IC is one of the first things a technician checks when one of these tablets won't power on or won't hold a charge. This chip sits on the motherboard as the main power management unit, controlling how the battery charges and how voltage gets distributed to the rest of the board. When it fails, you typically don't get a clean single symptom — you get a mix of charging issue, dead after flash, or a board that pulls current but never boots past the logo.
On the bench, a bad 8767-64 usually surfaces after a customer reports their tablet stopped charging overnight, or after a software update left the device hanging on logo with no way forward. Before jumping straight to IC change, check the charging port and battery connector first, since loose connections mimic power IC failure closely. Once you've ruled those out with a multimeter and confirmed abnormal current draw or missing rail voltage at test points near the chip, you're looking at a power IC replacement job.
This is where jumper lagana skills matter less than clean BGA rework. You'll need a hot air station set to the right profile for QFN/BGA packages this size, flux, and a steady hand, since the pads sit close together and overheating the board risks lifting nearby components. Reball the chip with matched solder balls before reflow if you're not getting a factory-fresh unit, and always clean old paste off the pads completely before placing the new IC — a rushed reflow here is the single biggest cause of return visits on this repair.
After reflow, don't just plug in a charger and call it done. Boot the tablet, check that it registers a charging current on your bench supply, and load a stress test or camera app for a few minutes to confirm the voltage rails stay stable under load. A power IC that looks fine at idle but drops out under load usually means a cold joint somewhere on the reflow, not a bad chip.
For repair shops running high volume on Samsung tablet faults, keeping a stock of 8767-64 chips on hand cuts turnaround time significantly. Customers bringing in a Tab 3 or Tab 4 that's dead after flash or won't take a charge don't want to wait a week for a part to arrive from Karachi or elsewhere — having this in stock means same-day or next-day service, which builds the kind of repeat business that keeps a workshop running in Lahore's or Islamabad's competitive repair market.
This listing is for the bare IC only. It ships without reballing unless your reflow station and stencil setup are already dialed in for this package size — if you're newer to BGA rework on tablets this small, budget extra flux and a spare chip for your first attempt, since first-try yield on tight-pitch tablet PMICs runs lower than on phone boards.
