I don't know what the "paper clip test" is, but please be very, very careful.
These Delta PSU's are switch-mode power supplies and are extremely dangerous to work on if you do not know what you are doing. They can store and discharge enough power to kill you, even when they are unplugged from the wall outlet.
When you replaced the CMOS battery, did you also disconnect the power cord and clear the CMOS with the jumper, as noted in my previous post?
When I had the PC open, I remembered that I had a similar problem a few years back and had to replace the video card ... I ended up putting in a Nvidia GeForce 9400GT at the time. I removed that, plugged power in and hit the power switch .. lo and behold, the machine tried to boot up .. beeped and the front power light came on ... popped the card back in and same as before - nothing, not a peep and no lights.
This leads me to suspect the video card is faulty - am I right? What's the best card that I could pop in - was it because this card needs more power than what the PSU is providing? Would really like to get this machine up and running again.
It's possible. I can't really diagnose a problem on the basis of this info, without observing the activity, but you could always obtain an inexpensive (or borrowed) working PCI-e video card with HDMI out, and use it as a test; and a full height card is fine if you leave the case top off for testing.
Or just pack your XL1 in the car and take it over to the Geek Squad guys at your local Best Buy store and ask them to take a look at the boot behavior.
If you decide to replace the card, in answer to your question, the current two state of the art RADEON GPU cards (both of which draw even less PSU power load than did the Sony/Nvidia GPU original OEM card for your system) are the:
Sapphire RADEON HD6670 low profile 1GB GDDR5, (480 stream processors) currently approx. $65 to $75 and falling, and the ...
Sapphire RADEON HD7750 low profile 1GB GDDR5 (512 stream processors) currently approx. $85 to $95 and falling.
Also, renninga posted that this can take upto 4gb of RAM ... I have 2gb installed as I thought that was the max it could handle as per Sony's guidelines. If it can take 4gb, I would much rather just upgrade to 4, and keep a bare bones Win7 installation running as my media PC.
It's Robert. Sony published the maximum "tested" memory. However your ASUS "TALAS" motherboard and Intel 945p chipset supports a maximum of 4GB. Note: the "best" memory throughput is achieved by matched pairs of 1GB dual-channel DIMMS. But if budget doesn't allow that, and if any of the DIMMS presently populating the slots in your system are 1GB modules, you can buy more DIMMS of the same manufacturer and exact specification (as noted on the paper labels on the DIMMS) and achieve a similar throughput to factory match dual-channel pairs (not quite, but pretty close)..
Most likely your system came with 533MHz DIMMS, which are fine, if that's what you have. If however you decide to start fresh with four (4) all new matched DIMMS, you should use the 667MHz DIMMS such as those at the weblinks I sent previously (Note: do not buy 800MHz DIMMS to run on an Intel 945p chipset).
If you watch for a special deal, you can sometimes find matched pairs of dual-channel 1GB DIMMS as low as $11.50 ea. (per DIMM in matched pairs). Matched pairs means they are benchtest matched by the manufacturer for exact throughput rates, and packeged in pairs after testing.
As for Windows 7, the best installation of Windows 7 for our VGX-XL* systems is to do an "upgrade" installation of either Windows 7 Home Premium 32-bit or Windows 7 Ultimate 32-bit; retaining your Sony software applications, setups, utilities and personal files.
Both Home Premium and Ultimate have an "upgrade" installation path, and "upgrade" (vs. "custom" also called "clean") provides the most seamless and satisfying end result and hardware drivers compatibility and functionality. Windows 7 is a dream OS for our XL* systems (Windows 8 is a monster!). Windows 7 is so superior to XP, and Windows 7 Media Center is a whole new world; leaps and bounds better performance than XL Media Center Edition.
Oh, and I also have a Win TV 1600 card installed in the empty PCI slot though that's not getting much use as of now ... haven't gotten MCE to work with that ever!
I have one of those too, but I never have installed it (got it from EBAY, and may install it in a scratch-build HTPC I am building.
My VGX-XL2A came with an AverMEDIA ATSC/NTSC TV Tuner/DVR card which works perfectly and very reliably with Windows Media Center. There are a couple of other Hauppauge PCI ATSC cards available, too, but I have no personal experience with them.
A lot of the XL* system owners who contribute to the AVS Forum "Sony VGX-XL3" discussion thread (which actually discusses all of the VGX-XL* models, including the XL1) have switched from using internal TV tuner cards to external multi-tuner devices by SilconDust and Ceton (some are connected to the home network router, rather than directly connected to the XL* system).
Thanks and hopefully, I can get this back to it's glory days with your help.
You might want to give our "Sony VGX-XL3" discussion thread a try. There are already almost 3,700 posts to the thread, and there's an answer there to almost every conceivable issue with a XL* model, if you use the search utility and do some reading.
