Graphics chip repair on the Dell Precision 7770

The Dell Precision 7770 has a separate, dedicated graphics chip. A separate graphics chip can be reworked or replaced on its own, which is what we do.

What we do

We confirm the fault is the chip and not the screen or its cable. Then we remove the chip, clean the pads and refit it with new solder balls (reballing), or fit a new chip.

We also clean the cooling system and replace the thermal paste, because overheating is what caused the failure in the first place.

How long it takes. Graphics chip work takes longer than most repairs because we test under load afterwards. We give you a timescale with the quote.

Warranty

This Dell Precision 7770 repair is covered by our 90-day warranty on parts and labour.
