Radiant Systems P1510

[jdmark]

I have a Radiant Systems P1510 that is isn't working. I'm almost positive it is the motherboard. Does anyone know what model the motherboard is? The chipset is an Intel 810E2 but I cannot find out the model of the motherboard to save my life. I'm waiting on a call back from Radiant Systems since I called a little later in the day.

If anyone has a working motherboard they want to sell me then please contact me. I'm not looking to sell this unit for parts unless you want to pay me a good price for it. The going rate on Ebay for a refurbished Radiant P1510 is $1,250. I'll let it go for around $1000.

Any help would be great, thanks.

Why not buy a small form factor pc, add a touchscreen for half the price plus the hardware is common stuff?

 

[jdmark]

Because it is worth way more if I fix it. Plus I would like to prove to my boss that I am capable of fixing hardware issues with the Radiant Systems POS computers. It would make me look incredibly good and would increase my value to the restaurant. I either want to fix it at cost and return it to the restaurant or resell it, making a decent profit. If I could just obtain a replacement motherboard the rest is pretty straight forward and simple.

The tech that came into the restaurant said it wasn't the power supply and simply said the unit was "fried". I can hear the machine turn on but I get no power to the touchscreen so it is either the motherboard or the monitor. I'm thinking it is the motherboard because when I plug the keyboard in and power it up I see no lights on the keyboard which are suppose to light up when the computer is booting.

Also, while inspecting the motherboard I see, I do not remember what they are called but they look like small batteries sticking out of the motherboard. One of them has some brown substance on the top of it that doesn't wipe off.

Thank you for your reply.

Did you remove the mobo?
Do any of the markings indicate the Mfg & model?
Is Radiant willing to sell you a mobo?
Did Radiant quote you a price for a mobo?
Did Radiant quote you a price to simply swap the P1510?

You sound like an asset to your employer, very nice. Let's hope they appreciate your efforts.

Hi guys,

I've got the exact same problem as jdmark - a P1510 that seemed to have a power supply problem - no boot, no nothing. I replaced the power supply and now I get fan power when I hit the on/off button, but no beeps, no display - even when I connect a VGA card to the PCI slot. And, no lights on a USB keyboard.

Besides the power supply, I've swapped out the CPU and the RAM - still nothing. My next move was also the motherboard, but I can't ID it either. Radiant doesn't want to help my friend (the owner) but would rather they pay their service partner for a refurb. I'd rather fix this one, if possible.

Jdmark - have you had any luck ID'ing the board?


thanks

Kevin

I don't know the model of the motherboard. I'm thinking it is proprietary but I could be wrong.

The problem is the capacitors. One of them has a dark colored substance on it and there are about 5 of them that are bulging which means they are bad. I am flat broke otherwise I would replace all of the capacitors and solder new ones on. I'll post an update when I get around to fixing them.

kevinkretz, take a look at the capacitors and tell me what they look like and if they are bulging and/or leaking.

 

[kevinkretz]

I see a row of seven next to two others aligned perpendicularly, and about twenty others, mostly in pairs. None appear discolored or misshapen ...

 

[jdmark]

None of them are bulging at the top?

 

[kevinkretz]

You know, when I read your post I thought "didn't this guy read what I typed?" ... but then, running my finger over the row of 7, there are definitely 2 whose metal top isn't recessed lower than the plastic like the others and are, indeed, bulging a little.

Very interesting. I'm not keen on taking a soldering iron to my friend's business equipment, though - just looking for a replacement board.

Thanks for learning me something!

 

[jdmark]

If you can find a supplier of replacement boards let me know.

Do you realize what the cost of replacing the capacitors is? $25 for the soldering iron and about 15 cents per capacitor, plus you've just gained a new valuable skill.

 

[kevinkretz]

I've got a soldering iron and know how to use it. Right now I have a friend's terminal disassembled - if I botch up a capacitor transplant who knows if they'll refurb the existing hardware - and plus , whatever electrical event happened fried *at least* the power supply and, we think, these capacitors. Why should I assume that other components on the MB weren't affected?

Why are you assuming it's the motherboard? I responded to another thread too saying that our video driver (I hope that's the correct term) was broken and sent it off to be fixed. They sent it back and that was it - cheap! Also, if the two bulbs are burned out, that could be it. Did you find out anything about the motherboard or determine the exact problem. I would like to hear.

 

[kevinkretz]

It's the motherboard because I ruled out everything else. It's not the video because I tried booting with a generic VGA PCI card - no video. More importantly, no keyboard lights, no beeps, and I am pretty sure the disk didn't spin up.

Add to that the fried power supply and the capacitor clues and it spells motherboard.

 

[jdmark]

Because when a machine starts it doesn't need a video card to boot into and successfully load the operating system. It is obvious from just looking at the motherboard that the capacitors are bad. They are leaking and bulging which means they are bad and need to be replaced. I haven't gotten around to replacing them yet since my priority this pay period was bills and buying a new netbook to replace this laptop.
