hi tournedos I replaced both TR20 and TR33 (driver transistors), they both were short circuited... And i also used a BUT12AF instead of the BUT12F. The stange thing is that nothing happens, the fuse doesnt blow and the TV makes no sound at all.. Need to get some other clamps, so i can measuere what happens.. but maybe I have overlooked something on

Hi I have tried to repair the power supply, and it seem ok, but the TV still don't power up. The red LED doesn't turn ON, and I can't hear anything... Do you think the (PowerFailure) protection is activated? Got any ideas? Could this indicate a problem or another module?
-
It seems to be discontinued, but i have seen it on some dealers websites... but not local, so I think i'll go for the BUT76 or the BUT12AF, which i can get.. http://www.nxp.com/#/pip/pip=[pip=BUT12F_1]|pp=[v=d,t=pip,i=BUT12F_1,fi=,ps=0][0 ] Nobby, have you seen this fault before? I have found following defects: - TR1 short circuit (power part)

Hey Í'm trying to repair the powersupply in a MX3500. I think the fault is caused by by the TR1. I'm having some trouble trying to find a replacement. Do any of you know any cross reference to the BUT12F transistor? Update: Seems like BUT 76 is a good replacement, http://www.datasheetarchive.com/crossreference/BUT12F.html . Below you
