Its a mx4000 beo4 and it says &quot;type:78/34 EDT&quot; at the back.</p><p>symptoms are: no respons when connected to the mains - no standby light, no humming sound or anything like it.</p><p>i measured 230V AC over P20-1 and P20-2 when connected - so its not a broken power cord :) - but 0V over C9 (supposed to be 300) and 0V between pin 1 and 6 on T6</p><p>&nbsp;if you have any clue or general tip - please respond!</p><p>many thanks</p><p>arvid</p><p>ps this might be a newbie question - while disconnected from mains I measured resistance between the C and E pin of TR33 (since it was the solution to the problem in the post I referred to) and got something like 600kOhm. A high resistance, but still not totally separated - would this mean that TR33 is broken?<br /></p><div style="clear:both;"></div>
