this morning I removed the chassis of my naomi cab. I found a paper stating that he had already been repaired. I spotted the D401 component. It looks like a transistor screwed to the radiator close to tht.

I will go to a electronics store to see if they have this component. I spotted more than R424 resistance has been changed. Perphaps I have to change it to be sure ? In addition the component Q404 was changed because the reference on this component no longer corresponds to that of the manual. The reference on the component is K2078 9J, should I change?

Grantspain,

I just come back from electronic shop and unfortunatly he didn't find any correspondance for the D401 component (ref FMV-3GMR).

Do you have an correspondance which I can find in europe ?

I tried to solder the component D401. I put the chassis in my cab but the screen does not turn over.

I think I made a big mistake, my chassis don't work anymore

well d402 is a double diode and just type into google and you should find,as for not starting then recheck your soldering and connections



also you could contact craig at www.giz10p.co.uk to see if he stocks this part

Hello,



I ordered a new chassis at giz10p. I just received it yesterday. Everything is now alright. Thanks a lot for your help, especially grantspain.
