problem with beovision avant 28
in The Workbench · Oct 6, 2009 14:53Hi again = I still have no cct diagrams for the Avant 28 but it sounds like you may have a LINE OUTPUT stage problem (hence the whistle noise). Unless you are used to working on LIVE tv ccts, where there are some dangero…
problem with beovision avant 28
in The Workbench · Oct 6, 2009 09:58Ok = Forget about PINs just now. Are you able to check circuits with a digital multi-meter? Could you find out if the PSU is running or not? Is anything happening at all? If you put the back of your hand on the screen fa…
problem with beovision avant 28
in The Workbench · Oct 5, 2009 16:28Hi there = Your problem is possibly with the PIN code. When the TV has been powered down for more than 30 mins, the PIN code has to be reactivated. Refer to page 61 in the User Manual = Regards Brian (Northumberland)

Beovision Avant curtains do not open
in The Workbench · Jul 21, 2009 15:06Hi there = It looks like the Horizontal Scan has failed. There are several circuit failures that could be responsible for this - some of which could be expensive, some not so! A common cause of this fault is failure of t…

Beogram 1000
in Imported Content (Unmapped) · Jun 19, 2009 08:13Hello again = The motor is powered by mains voltage ie 110 or 220v a.c., so unless you have technical ability and correct test equipment, you should not attempt repair with power on! You could, however, remove the motor …

Beomaster 6000 with a fault in the power supply
in The Workbench · May 14, 2009 16:07A bit more = If you look at the Service Manual for the BM6000, there is a very good explanation on the Fault Switch. Is the BM tripping to St Bi after a few seconds or almost instantaneously? If you do the test that I su…
