Hello,

trying to repair a Beolab 14 subwoofer. Problem is, switches on for about 5 seconds but after the 5 seconds it switches off again. In this 5 seconds it seems that everything is working and there is sound from the woofer.

After reading the manual and checking everything I found that the NTC module has not the correct resistance of about 470kOhm (measures about 550 MOhm).

Is there someone who can supply a NTC module? Or is there another thing I can try to replace it?

thanks in advance, regards

Hello,

beside of the NTC problem...

after further inspecting the mainboard I found there is a component missing, hopefully someone can point me in the right direction what is missing there or picture from this section.

thanks in advance, regards
