Hi all,

I switched on my Radias after few days of don´t use it!! and now after the loading time bar and the Logo of Radias, the logo remains in the screen and a text appears at top of the screen saying : SYNTH:Checksum Error!!!

I can´t play any sound and all the leds are off except the pots ones!!

I tryed to update the firmware again and don´t works, also I tryed to downgrade to the 1.07 version and the same, don´t works,

Please can you help me?, what happens to my Radias!!!

Thanks a lot for your time reading this post!!

This is speculation, but coming from the comp it world, checksums have to do with memory stack errors. So to me, your firmware is corrupt... as in it was not updated properly, but since you've said you successfully downgraded and reinstalled the current firmware, I'd say that shouldn't be the issue. Unless the install is saying it's done, when really it's not getting done as it should. (This is bad error checking on the part of the installer if this is the case)

The only other thing I can think of is your memory modules are hitting the fritz/wall. This could be just from time, heat, or a combination of the two.

Also if it's possible you should try a hard reset (as in set everything to default and clear all settings). Since I don't have the Radias yet and haven't finished reading the manual I'm not sure such a thing is possible.

I just figured in a situation like this the more suggestions you have the better your chances of getting it fixed again.

Of course if all software based fixes do nothing, then it most likely is a hardware malfunction and will require servicing.
