johnnyrw2's, First Look Under The Hood....Plus, A couple of questions to those who received the latest 3500's Quote:

The first thing I noticed is the small number of ventilation openings, second is the smaller power supply, noticeable the transformer. The main board appears nearly the same, does have an empty connector to the right of the USB board connector by tuner. Of course I will be interested in temperatures.
Some differences I see right away in the PS is that the front power switch is connected directly to the primary half of the PS. On the 3500 the power switch is connected to the main board. The main board of the 3500 might not tell the PS to do anything. Looks like there might be some difference between turning the HmWrx off with the remote and the manual switch. I don't see any added conductors between the two boards that would be for logic, Please check the HmWrx PS outputs and let us know if any voltages are always present on the main board and the what those voltages are. We know that with the 3500 we have constant 5 & 12 VDC. I'd bet that the HmWrx PS always outputs the 5VDCto the main board and the front panel button switches the 12vdc on and off.
For some reason(s) there is a difference in how the HmWrx STB are powered.
I'd have to pull my 3500 PSB out to check this. On the PS there is a jumper CN2 located next to where the AC connects (CN1) to the PS. This very well could be where a separate power switch would be connected.
Will be interested to see what temp reading you get.
Can't tell from your photo. Is there a different heat sink on the main processor?
Looks like the footprint of the case is deeper (front to back).
The silk screened PCB number on the main board (KLF7816-ATSC-01 A3) is the same on both HmWrx and the 3500.
The PCB itself exactly the same (so same board number) but that does not necessarily mean that all components would be exactly the same as used on the 3500, Components could be different and still share the same footprint and solder pads. Example would be on the memory chip...... Same basic chip but with a higher capacity.
It would be interesting to see if the latest shipped 3500's have a different PS. Hint, Hint Question to anyone who has one of the recently released STB3500 PVR's
Only if your are capable and wiling, Can you look inside the 3500 and report if the power supply is different from the one pictured on page #1 of this thread.
In the set-up menu on the INFORMATION page where it shows the firmware version V7, Does it still show "TEST" and what is the actual version number.
On the firmware V7 some of us are running, Our 'Information page reads:
Model ATSC - TEST
SW Version CL630133 130618 V7
Just curious to see if the V7 we have is any different from that being shipped.
I checked on the iView site and they not have V7 available for owners to download.
Since they posted V2 for up-grading I'd think they would make available V7 which is being shipped with new STB's.
