Small Bartop Screen Issues

<< < (2/4) > >>

gajaman:
Thanks Daniel, I'm pretty pleased with it.

No, I didn't have a thread going for the build beacuse I've built controls and a cab before, I just scaled things down a bit.

I started the project half with the idea of maybe making ten or so and trying to sell them as a budget base unit for emulation/classic games playing. The reality is that with the cost of the PC, screen and a windows licence coupled with the time the build took it wouldn't be a very budget product! Also it weighs loads, the shipping would be killer!

I did some "testing" last night (well, I played Speed Rumbler for a while). The unit was on for an hour and 15 minutes before the flickering commenced, but after 2 or 3 minutes it stopped and didn't reoccur in the next 25 minutes when I switched off. Makes me wonder about the heat, surely if the problem were caused by heat it wouldn't stop for so long as the unit wasn't getting any cooler?

Maybe the screen is defective?

I've seen this on my wifes old notebook.  VERY similar sounding to me.  I ended up buying her a new notebook (it was time anyway). 

But some questions.  Is the screen still there, but the back lighting turning off? 

Can you remove the screen and have it just sit next to the cab?  I dont' know if it will help, but It might give you some ideas.

I'm guessing that its power to the monitor.  thats seperate unit right?  Is that exposed?

Good luck.  But I would consider looking around on ebay or friends.  15" lcds are cheap these days.

You need to isolate the problem first. It's going to be one of; the LCD, power supply, driver electronics, inverter or graphics card.

The easiest thing to isolate first would be the graphics card.

Nice cab by the way. What size motherboard do you have in there, one of those micro things?

gajaman:
The mother board is a standard size, just a spare pc I had sitting doing nothing, it's a tight old fit. I'll add some pics of the insides when I get a minute.

I do have a spare flat screen that is identical, maybe I need to swap this out. I could then run the (poss) defective screen off of another PC and see what I get out of it.  Problem is to swap out the screen I need to dismantle the whole cab and all of the sub-assemblies within, a bit of a pain. I still haven't done the "fan blast" testing suggested by Daniel, maybe I should try that first?

mountain:
Nice bartop! I have kicked around the idea of building and all gloss black bartop with chrome accents for a while now. Post some more pics when you get a chance!
