Comunque sia sembrano vari casi in cui il Led flasha rapidamente, innanzitutto servirebbe sapere se il display si accende e dà messaggi strani o se "flippa" oppure se completamente spento.
A occhio il tuo problema potrebbe essere uno di questi:
- A1 CPU Control Board LED.
The CPU board's single LED will flash continually and evenly if the board boots correctly. If the CPU board's LED flashes very fast for a second, then pauses just a moment, then repeats, this usually indicates a low CPU board battery or a bad U11 chip.
oppure
- the original Lithium battery has started to cause corrosion
damage to the Dallas U6 chip and the CPU board. This particular board's battery had
damaged the U6 chip enough so the game would not boot correctly (game booted with
nonsense text on the DMD and a very fast flashing CPU LED, and the game would not
go into attract mode or self-test).
