I sent my SMPS and AC Input board to Curt for repair after some trial and error diagnosis in this thread:

https://www.curtpalme.com/forum_archived/viewtopic.php@t=2858.html

Anyways, got the parts back, slid them in, the standby light turned on, tried to power up (hit standby) nothing happened. Checked the other switch, it was engaged. Hit all the other buttons on the remote - nothing.

All of the LED's that were in the panel next to the dip switches were lit up red, except "main power" which was dark. I scanned the area of the boards, and did not see any LED's lit anywhere.

Any advice?

Hmm - looks like I have my project for tonight based on this:

Okay,

I pulled each board one-by-one - - nada.

All of the diagnostic LED's recessed into the cover are still lit red (except main power which is dark).

Any tips. I'll e-mail Curt next week if he doesn't see this for his opinion. I know he's back from Vegas, and that can take a lot out of a person.

When you push the main power button on the back, does the red standby light come on? Does the processor light blink?

Standby light comes on. All the LED's recessed in the rear cover come on, the remote (which I switched out with another one since the original one had a crappy spliced wire, from Hammerhead when I ordered some HD-144's) lights up.

I don't know where the processor light is, but I don't remember seeing anything blink.

OK, look at the lights on the controller board. ONe should be blinking.

Try this:

Press the recessed button on the wired keypad that might be labelled 'addr' or might be blank. Once you press it, then press '0,0,0'.

See if that resets the controller.

Thanks Curt. I'll check it out tonight.

The boards arrived in great condition, too. Hopefully it isn't something too weird, although the fact that my SMPS had a unique problem to fix doesn't inspire confidence.

I am okay either way since there is a perfectly functional 6PG+ sitting next to the barco in the basement. If the barco wasn't a bargain, I'd be working on figuring out the learning curve on the NEC. In a perfect world I'll get them both running and pick the one I like better.

We'll get it running. You're at least part way there. I do remember the problem. A feedthrough connection on the PC board had opened. THe power supply only turned on part way. We'll figure it out!

Okay. Tried pressing the recessed button (blank on the remote) then 0, 0, 0. Nothing.

Tried holding down the recessed button then 0, 0, 0. Nothing.

Standby light is still on. LED's recessed in the pannel (controller board I assume) all still light up red except the one labeled "- Main Power" which is dark.

Nothing blinks. Even turned off lights to make sure I wasn't missing anything. I suppose the "-Main power" could be a dead LED, that otherwise would be blinking . . .

OK, wait, they ALL light up????

That's way wrong! That controller board is bad methinks. The oddball voltages in the power supply might have fried it.

Try reseating all of the connectors on it. Take off the metal cover covering it, and press down on the chips that are socketed, and reseat all of the connectors for the yellow wires. MOst of those lights should be off, the processor one should be blinking.

If that's a no go, send me the controller board.

Okay. Thanks alot Curt. I'll try the reseating the sockets and connectors and post back this weekend.

Appreciate all the help.

Okay, no change after reseating the connectors and pressing on the chips. ALL of the LED's but main power still lit. I can send you the controller board, but I am going to send you a PM about the particulars.

Thanks again for the feedback / troubleshooting.

Now this is what this forum is all about! Curt you're the man!

Ok Curt is the man - he sent me a replacement controller board. He even told me the hours on my machine (5k), which I hadn't known.

Now about this @#$)(! machine . . . . I installed the controller board, and for the first time since I owned it, the machine powered up. Got a short puff of smoke, but it powered up. And that was about it.

The Red LED on the Vertical Board lit up, and the "RCU" error message lit up.

After a minute the machine would just hum (no more smoke). Pressing the buttons didn't yield much. The tubes never lit up. Its got a pulse now, so I am happy about that. . .

I am wondering if my weird voltages in my failed (now repaired) SMPS wrecked havoc, or if I am real close now. . . Any input?

Thanks, Dave

Hooked up a dvd player. It powered, light on the V board was still lit. With dvd player running. Pressed 2 to select the port number. Not much came of it. Noticed the blue tube had a small ribbon of activity across the top - kind of like static, fainter and much smaller was the red. I thought I saw it on the green, but I can't be sure. Grabbed the camera - battery was dead. Grabbed the camcorder - it works, but I don't have the cable to port it (and its memory card for stills was full).

I need to do some reading to figure out what's next.

You're getting there. Next you can buy an Ampro Wink

Stupid set!

Smile

I remember you told me that you've never seen this set running.. i'm wondering if you ended up with a set that was used for parts, that a number of bad boards ended up being put into it. The SMPS and controller board problems aren't really related.

So, let's start from the beginning. Smoke is never a good thing, esp in a projector.

Look at the G2/diagnostic LEDs. Is the red on, and all of the greens on?

The fact that you see light on a tube seems that you have HV and deflection and that the SMPS is working.
DId you remember to plug in the wire that goes from the controller board to the RGB Switcher board?

Did you see where the smoke came from?

not to put you off the Barco repair but my first pj was a pg6+ and I have to tell you that the adjustment potential was one of the best thing about it , I only have my Barco to compare with but I found the NEC rumours unfounded and really enjoyed the process and results. do it over a night or two, its not plug and play but has great payback for time invested. I would love to see one of the XG/LC projectors dialed in!!
