With the pandemic leaving me with some time on my hands, I'm finally getting around to diagnosing a batch of LCD Megatouch machines that I bought last summer. I've been able to get 3 working with just a new CMOS battery, but 2 other units are giving me trouble.
#1. Ion (2010 key)- After I replaced the CMOS battery, discovered that the hard drive was toast. Took it out and tried to put it into my main PC, couldn't be seen in BIOS. Replaced the hard drive with a spare (2010.5), and it will post sometimes, mostly the screen will flash "No Input Signal, Check Connection" every few seconds. Capacitors seem iffy.
#2 Aurora - Haven't popped it open yet.
After reading all I could regarding the purple ECS boards, and how crappy they were, i started scouring Craigslist for options. I found someone selling a few A7N8X-VM boards with RAM, CPU, HSF, etc. That leaves me with a few questions to get me started
- 1. A7N8X-VM has only 2 ram slots, the ECS board had 3, but only the middle one has a stick. Is it okay to have both slots populated, or should I just have 1 stick per board.
- 2. If just 1 stick, is 512MB ok or should I use 256MB?
- 3. I'm not sure what CPU came with the boards. The HSF is too tall to be of any use, so I'll have to switch them out and I can check their specs. Does it matter, or will just about any Socket A cpu work?
- 4. I know I'll need to jumper the audio to get it working, any other issues to worry about
