Repair Diagnostics in Fullerton, CA
Plenty of devices arrive with a symptom rather than a diagnosis: it will not charge, it restarts, it gets hot. Diagnostics is the step that turns that into a specific, repairable fault.
You get the findings and your options before anything else happens — no work goes ahead until you have approved it.
We do not publish repair prices. A technician confirms your exact price by text and email before any work starts.

When A Diagnostic Makes Sense
Two Levels Of Diagnostics
- Standard diagnostics — typical plug-and-play faults such as screens, batteries, ports and common component failures. Generally completed the same day, usually within about two to three hours.
- Advanced diagnostics — liquid damage, no-power, data recovery and board-level cases. These take four hours or more and sometimes several business days.
What Happens During A Diagnostic
- 1
Intake and history
We record the symptoms, what happened before them and what has already been tried or repaired.
- 2
Testing
Standard cases go through functional and component testing. Advanced cases add measurement of the board's power behavior under a microscope.
- 3
Findings
We explain what we found in plain language, including anything we could not confirm.

Your options
You get the repair options and your exact price by text and email, and you decide whether to proceed.
The Diagnostic Charge Can Apply To Your Repair
Diagnostics are charged when the issue is unknown or needs testing. The approved diagnostic fee applies toward the final repair when the repair is started within five days of issue confirmation. We do not publish diagnostic prices — the fee is confirmed with your quote before you approve it.
Turnaround
Standard diagnostics are generally same day. Advanced diagnostics take four hours or more, and liquid-damage or board-level cases can run across several business days.
Warranty
Warranty applies to the repair you go on to approve, and the term depends on the repair and part used.
Warranty varies by repair and part quality and is confirmed with your quote. See the full warranty policy.
Frequently Asked Questions
What is the difference between standard and advanced diagnostics?
Standard diagnostics cover typical plug-and-play faults such as screens, batteries and ports, and are generally done the same day in about two to three hours. Advanced diagnostics cover liquid damage, no-power, data recovery and board-level faults, take four hours or more, and can run across several days.
Does the diagnostic fee count toward the repair?
Yes. The approved diagnostic fee applies toward the final repair when the repair is started within five days of issue confirmation.
Do I have to approve the repair after a diagnostic?
No. You receive the findings and options and decide from there. Nothing further is done without your approval.
Do all repairs need a diagnostic?
No. When the fault is already clear — a cracked screen, for example — we quote the repair directly. Diagnostics are for cases where the issue is unknown or needs testing.
