I attempted to repair the PSU burn out issue. Replaced FET, resistors, 3845 chip, With no FET fitted I see 46 KHz pulses on gate pin. However, when I fit the FET and power up. FET blows again. I can’t find any obvious shorts on secondary side of PSU +U, -U, +/-15v, 3,3v. I’m a struggling. 

Any suggestions?

P.S I have schematics for PSU, input and display pcb. 

Can anyone send me schematic for power amp section please.

Thanks in advance

All I get is a foul smell and a loud low-mid frequency humming noise and the screen wont light up anymore.  So I need all the help I can get please.  Is the amp complete toast?  Is it a matter of replacing a few components?  There is no evidence of any damage whatsoever (just the smell, but nothing looks burnt, melted, or damaged.  I don't know how to troubleshoot.  But I do know how to read a schematic and solder. 
 
I NEED SOME GUIDANCE PLEASE!!
 
THANK YOU,
 
DAVID

Hi everyone.  One of our 4 ZLX-12bt speakers has no low end, the LF driver tests ok, but we measured audio output only on the HF amplifier.

Can @Voron or anyone that has decent resolution schematics please send the power supply and amplifier stage circuits to me at info@greenroomtyler.org

Greatly appreciated!!
