check to make sure none of the caps are bad. the way you do this. is to see if they have lump at the top of them. they should be flat. if all but 1 have a lump that is the bad cap. and the source of your problem. .05 fix

update,I am still trying to repair two of my frineds sonicview 8000hd's power supplys.
Number 1:when the sonicview is powered on shows no readings at all no lights fan etc, replaced c10,c11,c12,c13,c24, and d6
Number 2: Has one light, fan works and orange light on display when you hit a button replaced c10,c11,c12,c13,c24, and d6
Has the readings:
2.4V for the On/off
5.2V for the 5V
11.0V for the 12V
0 for the Ground
1.3 for the 3.3V
1.3 for the 3.3V
5.0 for the 5V
5.0 for the 5V
25.3 for the 22V
25.3 for the 22V
0 for the Ground
31.0 for the 30V
I',m assuming the issue with this power supply is I can't get it to get 3.3V besides the capacitors c10,c11 and c24 and d6 what else could it be?
thanks

Looks like my HD8000 is now in the "dead" category with the above. Not so easy to diagnose when the voltages are close (and no schematic). I have 2.6 for the 3.3, 25 for the 22v, 5 for the 5v. So while my 3.3V is reading 2.6 is that NOT close enough?
Over the past few days my HDMI interface was getting "weak" and I have to unplug and replug it to the HDTV to see the menu. Now, the display is out and no menu/video on the TV (using the yellow video out on the bench.) No puffy caps either! Why could it not just burn up...something obvious to fix! I hate to start replacing parts in the chance I get one right! Any other suggestions?

The 1.3 volts or the 2.6 volt reading instead of the normal 3.3 volts means that a voltage regulator IC has gone bad, or there is an excessive DC current load on that part of the circuit.

I also would not use the receiver to test the board as you may fry something non replaceable on it, some sort of DC test bed would be needed, but you need to know the DC current ratings for all the DC voltages, remember DC voltage is half the circuit, the other half is the correct current supply and draw.

Without a schematic of the board you will be hunting in the dark without a flashlight, also trying to find some of the replacement parts may be difficult, as they may be custom made for that board, I would look on the web for a replacement board, or a repair center, (look on E-bay) and don't look to Sonicview for parts or replacement as they are long gone.

With several dead power supply's to reverse engineer and one or two working ones, a schematic and test bed could be developed, but that would take some time and may cost a few bucks.

You used to be able to buy them on ebay... ebay seller Danmarco was the supplier and seller of them.. he sold out of them about a year ago now... He offers a repair service for these power boards now.. Great seller and person to deal with, I have made many purchases from him before.. check his other parts for sale to.. he has 8psk boards still.

Well, I replaced the C10, C11 & C24 and the 3.3 is now correct.
However, something else must have died as the LCD display is still blacked out, and the menu never comes us.
You are correct Fishbum, even with a schematic it would be difficult of not impossible to find and fix. At least a known working good unit to compare against but....Anyone need a repaired power supply? I'm in the market for a new receiver.

Could you tell me where you got the capacitors?

C10, C24 ....... Rat Shack part # 272-1032 = 1000µF 35v 85º Radial lead capacitor if your in a hurry ...... about $ 1.99 at most locations.

But if your not in a hurry go to digikey.com and get the 105º C, 35V, 1000uF caps, they will last a lot longer.

Great, thanks. Are all the caps the same?

The 10 volt caps can be replaced with 10/16/25/35 volt units if they will fit in the same location on the board.
The caps for 3.3 volts can be 10 volt units, the 5 volts can be 10/15/20/25/35 volt caps
The caps for 12 volts should be 16/25/35 volt units.
The caps for the 22 volt supply should be 35 or 50 volt units.

When replacing make sure you have polarity correct.

I've never heard anything so true, I have 3 dogs. Thanks for the help. Turns out all is good with my unit...just had to mess with the TP's.
