You got all the tools you need :-). The very first thing to do is to follow a basic approach to testing a few things. To determine if it is your power board follow this along:
 
'''Does proper Stand-By DC STB5Vappear at BD100?'''
 
If No
 
Change the Main Power assembly
 
If Yes
 
'''Does proper Inverter DC 120V appear at CN801 in IP?'''
 
If No
 
Change the Main Power assembly
 
If Yes
 
'''Does proper Inverter DC 120V appear at CN801 in IP?'''
 
If No
 
Change the Main Power assembly
 
If Yes
 
'''Does proper DC STB3.3V appear at C101?'''
 
If No
 
Check IC105 Check the Main board
 
If Yes
 
'''Does proper DC D3.3V,B8V,CORE1.1V appear at C108,C110,C137?'''
 
If No
 
Check IC101,IC108,IC102 on the Main board
 
If Yes
 
'''Does proper D1.8V,A2.5V,A1.2V appear at C115, C111, C112?'''
 
If No
 
Check IC104, IC106, IC107
 
Let us know what you find. We do not have a good picture of all of your boards etc. to point all of those components out. So, see if these work or you’ll have to do that and tell us what you find. Of course you should also measure the power board connector and compar that to the values printed on the board.
