Re: SAMSUNG UN60J620DAFXZA has strobing backlight w/ mb crash
Awesome, I wasn't aware these existed. I have an LCD panel tester with lots of different LVDS cables, but it can't test high voltage LED strings.
This also looks like it would come in handy for other types of LED applications, and it's a lot more portable than my bench supply LOL....

Re: SAMSUNG UN60J620DAFXZA has strobing backlight w/ mb crash
Which LED tester did you use? I've always done it the hard way, using a bench power supply and series resistor. Probably not practical in something as big as a 60" TV though....Leave a comment:

Re: SAMSUNG UN60J620DAFXZA has strobing backlight w/ mb crash
I am working on a similar TV that uses the same power supply board. As soon as the power cord is plugged in, the backlight flashes on and off. The +13v output is around 5 volts. If I unplug the backlight LED connector, the voltages appear normal. Should I assume that there is a problem with one or more backlight LED strips, causing the PSU to shut down?
The odd thing is that it behaves the same even if the main board is disconnected (leaving just the AC cord and backlight), except that it flashes at a...Leave a comment:

Re: Intel server board, REALLY frustrating BIOS issues!
The battery tested good at 3.14 volts. I'm hesitant to mess with the BIOS until the owner backs up their files. Though it appears to already have that version installed.
I'll have the system back in my shop next weekend to do a video card upgrade, and I'll look at it some more then....Leave a comment:

Intel server board, REALLY frustrating BIOS issues!
Long time no post guys! But I remembered to drop by here when this system stumped me today.
I'm working on an Intel S5000XVN for a customer. When I press F2 to enter the BIOS, it says "Entering Setup..." on the screen, but then proceeds to boot the OS, no matter what I do.
If I disconnect all drives from the SATA ports, it will go into the BIOS on its own.
It also changes the boot priority on its own. I'm not sure how to explain it. But if I connect only the DVD drive, I can boot from that. But after connecting the SSD with the OS on it, it... -
LVDS connectors and cables for LCD's
Lately I've been doing a lot of work with LCD's, and have needed to get various types of cables, inverters, and control boards depending on what type of panel I'm working with. But I've been a little confused about the cables and connectors.
When looking at LVDS cables on Ebay or other sources, they are often numbered something like "FIX-30P-S8" or FI-X30-D6".
I know that the FI-X is a JAE connector series, and I assumed that S8 would mean single channel 8 bit, D6 would be dual channel 6 bit, etc., but that doesn't seem to be the case. Any idea where... -

Livestream is driving me crazy...
Anyone else been having issues with Livestream crashing Flash regardless of browser used? Every time I load up a channel, the ad will play, and then the video window goes black. Within a couple seconds, it locks the browser until I stop the Flash plugin.
Seems I'm not the only one having this problem according to the Livestream forum, but nobody has found a solution yet. -
Re: HP/Asus MOCA-AR, need heatsink

HP/Asus MOCA-AR, need heatsink
Anyone have access to one of the HP slimline systems with the MOCA-AR motherboard? I bought a couple of these off Ebay to experiment with, and I can't find a source for the CPU heatsink. It's mounted with the diagonal clip style. If I at least had a part number, I might be able to track one down.
This is an interesting board, which should make a nice HTPC or office desktop. -
Re: Building a NAS, need opinions
Well, I ended up with the DS1813+ and 9 new HGST 3TB NAS drives. Yay for $2,400 worth of gear that probably won't last as long as my old server
I almost went for the 2TB enterprise drives off Ebay, but I figured these would be good enough for the job, and give me an additional 6TB of capacity. I bought an extra in case one of them is DOA, but it's good to have a spare either way.
At least now I have a good reason to get off my butt and sell a bunch of stuff, which will give me more room to work.

Re: Building a NAS, need opinions
Right now my biggest issue is picking which hard drives to use. I can get the Hitachi ones from Ebay, or some other (slower/cheaper models) from Newegg for around the same price. But it seems like every drive I look at has a high failure rate. Though maybe it's because people don't bother leaving reviews when they actually work.
My existing NAS uses a bunch of ancient drives with over 50K hours on them, and most are old Seagate Barracude 7200.7. I've had 2 or 3 fail in the last couple years, but they were old when I got them. I probably...Leave a comment:

Re: Building a NAS, need opinions
I've been doing some more digging, and I really like this one too:

4x LAN trunking looks like a beast, and the software seems powerful as well. Also 4GB RAM capability, which is a bit better than the QNAP.
If it will work with the Hitachi/Dell drives that are on Ebay, I think I'll have a winner. Nowhere near as fun as DIY, but I just can't match the price for what I get from it.Re: Building a NAS, need opinions

Re: Building a NAS, need opinions
As much as I love Western Digital, I'm never touching anything other than the Caviar Black or RE type drives. Those cost $200-300 each.
The 2TB drives on Ebay are listed as New.

I'm thinking this QNAP might be a good option if those Dell drives work with it. It's certainly lighter and more efficient than the old PE 2900 would be.

Re: Building a NAS, need opinions
Another thing I'm considering is something like the Qnap TS-869-PRO-US. Someone on Ebay is selling 2TB Dell Enterprise drives for $100 each that would probably work in it, so that would set me back about the same amount as the Poweredge 2900 setup. Only drawback is 12tb vs 16tb.Leave a comment:

Re: Building a NAS, need opinions
Thanks, I'll look into that a bit. The 990FXa-UD3 is what I have in my daily use PC too.
I forgot to mention though, another reason I like the Dell is for the redundant power supplies. I was planning one plugging each one into a separate UPS, so that the system can stay running even if I have one UPS fail. My existing NAS has a 2+1 redundant PSU with hot swap, which is handy. But it's very old and tired now, and only about 64% efficient.
I think I'd still go over budget with DIY build, since a good...Last edited by Maxxarcade; 03-07-2014, 12:43 PM.Leave a comment:

Building a NAS, need opinions
I am currently using a very old server as my NAS. It has 16 IDE drives and tops out at about 3.6 TB capacity. It also uses about 330 watts at idle. Since I'm out of space and it costs too much to run and maintain anymore, I need to move to something newer.
My needs are something with true hardware RAID 6, hot swap drives, at least 16 TB in RAID 6, and less than 330 watts. So far I've got my eye on a refurb Dell Poweredge 2900 Gen 3 with 10x 2TB drives, PERC 6i, 16GB RAM, Xeon L5420, and remote access card. Total cost is around $1,800, which is far cheaper than anything I was able...Last edited by Maxxarcade; 03-07-2014, 11:14 AM. -

Re: Need advice on a new LAN switch
Just an update, I picked up a brand new Procurve 1810-24G v.2 for $189 shipped. Here's hoping it works out for what I need.
Also got a bunch of CAT-6 patch cables of various colors and lengths to connect everything in the rack. Up until now, I've been using homemade CAT-5e cables that are all solid wire and the same color.
This is the first time I've used a managed switch, so I've got some reading to do before it arrives.
Also need to get some cable organizers and clean up this horrendous mess! (these are...Last edited by Maxxarcade; 09-16-2013, 04:54 PM.Leave a comment:

Re: Need advice on a new LAN switch
I think I'm going to aim for a Procurve 1810G-24. It's a bit more money, but probably worth it from what I've read.Leave a comment:
