Screen upgrades and replacement shells
Aftermarket screens and shells vary widely in quality. They can be fitted only where the exact kit, power demands, shell modifications and final value make sense. Original parts will be preserved where practical and returned if requested.
Leaking batteries can cause damage beyond the visible contacts. Remove batteries from stored equipment and do not power a badly corroded unit before assessment.
Handheld repair questions
Can every missing screen line be repaired?
No. Some faults are connector-related; others are internal to the display and require replacement. The exact model matters.
Can you brighten yellowed shells?
Plastic brightening can be considered, but results vary and yellowing can return. It is never treated as risk-free.
Will you fit parts I supply?
Possibly, after checking compatibility and quality. Supplied parts cannot automatically be guaranteed.
