Samsung Galaxy Book Ultra Repair — your questions answered
How much does a thermal repaste cost on the Galaxy Book Ultra?
A full vapor-chamber service including flush, new phase-change pads and fresh paste on the Core Ultra 7/9 and RTX 4050/4070 is $280-$340. Turnaround is two to three days with a 90-day warranty on the work.
Can you reflow an RTX 4070 in a Galaxy Book Ultra?
Yes. Cracked BGA solder joints on the mobile 4070 are reflowed or reballed using a controlled thermal profile. Success rate is typically 60-75 percent; if the GPU is damaged beyond repair we quote a board replacement instead.
What does a new 16-inch 3K AMOLED screen cost to fit?
Genuine Samsung Display 16-inch 3K 120 Hz AMOLED panels are $1,400-$1,800 fitted. This includes data cable, adhesive, calibration and 90-day warranty. We image your drive before any work begins.
Do you offer onsite repair for the Galaxy Book Ultra in Sydney and Melbourne?
Yes. Our technicians can attend your home or office for software diagnostics, fan cleaning or connector repairs. Board-level work such as GPU reflow or screen replacement is completed in our workshop with insured courier return.
Is there a warranty on Galaxy Book Ultra repairs?
Every repair carries a 90-day warranty covering parts and labour. If the same fault returns within that period we re-attend at no charge, provided the device has not been opened by another party.
