Hi guys,i have a Q9c4 in for no functions ,found the soft start button on the front not working,have replaced it ,now that part of the circuit works ,but it will not fire up,any clues on this one,thanks russell.

Check inverter transistors/FETs. 2 may be s/c.Uses 2sc5707 I think. May also be a link fuse between the transistors.

Hi bill,I need to get a contact phone number for parts and circuit please.

Last contact number I have - and it may be obselete now - is Fax 02 8988 6538, Tel 02 8988 6500 for BenQ Australia 6/2 Holker St., Newingham NSW 2127.

Thanks Bill, I will let you know if it is still a current address.

You can get the transistors from WES and also the pico fuse if it is blown (it will be a 3 amp). If you can post a pic. to me I will be able to assist more. Check the discussion group for my email address.

Hi there,correct me if i am wrong,but this model is completely different to the models that have the tr/s and picofuse problem,which i am familiar with,russell.

Just for techoff2, no need to post your email, it's available in members centre. Noticed it has changed, you might need to contact admin to correct it.
