TM5402HD won't come on

[rigsby71]

Hi, I am just looking at a friends TM5402 M3 & all it's doing after being powered on is constantly flashing the four dashes on the display. The box apparently does this four around 4 hours & then it will boot up.

Has anyone else seen this before ?

Sounds like a bulging capacitor needing replaced on the psu. As it heats up after a few hours it comes on.

You could try a factory reset flash latest technomate software and do a scan sometimes it can be corrupt files. hth
