I put the PSU board in and so far working great. Been on for 6 hours so far.
A big thanks to everyone who helped me, especially Tom and TW. You guys are awesome.

Sorry...lol just trying learn and understand things better.Leave a comment:

Re: Z50PJ240 Powers on then back off clicks but no picture
ok thanks, good to know. I was going by a diode video test that if it was beeping it was opened and probably bad, but it was an out of circuit test by itself.
So if it were out of circuit would it test differently?Leave a comment:

So the new board is correct because of the resistor that is parallel and the old one on the right is bad then?Leave a comment:

Yes, the board on the left is the new one.Leave a comment:

TW and TOM
I got the new PSU but haven't installed yet. The D304 diode seems to be open, so this could be defective. I have a pic of the diode and a video link of me testing it. Do you guys think this would give me trouble if I install this as is. I don't want to mess up anything else. I still have a good diode I could replace it, or maybe I need to send it back. Does it look bad to you guys?

I'll try again, seemed way off compared to yours.Leave a comment:

Re: Z50PJ240 Powers on then back off clicks but no picture
Can't figure out how to check that correctly. On P1 do put 1 lead on pin 5 and check all the other pins?Leave a comment:

testing the YSUS
grd to VS is 3.37
grd to VA and grd to 5v starts out about that but starts dropping
don't see 15 v
What is yours?Leave a comment:

Checked the diode in diode mode and the resistor in ohmsLast edited by soog35; 10-31-2013, 02:45 AM.Leave a comment:

What should that diode read?Leave a comment:

visually it looks fine but I get 00.7 on that resistor.Leave a comment:

Re: Z50PJ240 Powers on then back off clicks but no picture
Since I won't get new PSU til Friday I went ahead and did this Control board test from the training manual, since the LED never stays on. Looks like the control board is good. Going to check the buffer board for shorts. Was a little unsure how to do that until i found video on YouTube. Turns out its Tom, glad to say you have another subscriber.
TW you also said to check Y-SUS and Z-SUS for resistance at the connections. Where do I put the leads? It has a lot of things to check in those manuals, but its a little...Leave a comment:

Brentsky my D304 is 266.3 and the 3 white resistors were good, didn't have to replace them. I'm hoping the power board is my problem from the test I did.Leave a comment:
