Thanks Mac. I didn't think I could check it in circuit since the Marquee shuts down HV when it senses a problem, so I was basically going to bread board the basic circuit and scope the output that way since I have a funciton generator and a DC triple power supply to drive it.
I forgot to use my handy NTE cross reference program! I may pick up a few as spares.

They are cheap enough that its easier to just buy one if you want and replace it rather then spending all that time just trying to test it.
By the way, that chip is commonly used in Panasonic tvs.

That bad boy is $12 a piece!  I suppose I can just replace the fusible and see what happens as well. If it's bad and shorted, it will just blow the resistor again. I guess that's easier than doing a bread board curcuit. At $12 a pop from Newark. I'll have to keep searching a bit more.

You know, I PMed him that link cause I dont think Curt appreciates all this info on his site for all to see. It affects business. I know I wouldn't be to thrilled.

Sorry Curt, I didn't mean to offend. If one of the mods wants to strike out the IC search posts, that's fine.

No offense was intended. But I know a lot of threads on here discuss specific Marquee repair info that when in open posts give others that are not regular members that inside info on repairs they would other wise have to be sent to Curt. And I'm not talking about the mods stuff as Curt wants nothing to do with it. And I know most just want to help others out and I sometimes find myself wanting to post more info on the repair. But I dont for the specific reason of this site being here. Curt may not comment but I know it does bother him a bit. Cause its his bread and butter.
I would suggest if you really want to help a fellow member with a specific repair that its done via PM or email. 
Damn-it, now I'm the forum troublemaker.....

I wouldn't say so Mac. I honestly didn't know specific info like this bothers Curt, so I would rather know so I don't do it in the future. Again, apologies. This started by me asking the opinion of those of you that have repaired a lot more vert modules than me and it sort of morphed a bit. I suppose even that question got a little too specific as well, which is probably why Curt didn't respond to it. I'll post back when I have it fixed to wrap up the thread.

Wait a damn minute now....since when can't those of us who are willing to accept the risks of kludging up our machines and raising the white flag are censored? Not everyone is willing to do what a handful of us WANT to do to take our hobby to the next level. Those that can't, buy. Those that can, buy parts.
What about all the machines being parted out lately?...THAT isn't considered more harmful to Curts repair business than a few guys wanting the satisfaction of troubleshooting and repairing their own boards?
Hell, if it weren't for the few of us that want to do that, with exceptions of course, there would be NO technical discussions and community troubleshooting going on at this site. It would be just another facade site whose sole function was to offer a water cooler for consumers to gather round whilst deciding what to buy from vendors.
Another thing to consider is this...when new CRT pj owners have problems they hit Google. Google leads them here. From here they can contribute to the site, to general knowledge perhaps, buy from vendors, and possibly enrich everyones experience.
Let's just let Curt decide if he wants to start a rebellion because as far I remember there's only one rule...NO SELLING WORKING PROJECTORS WITHOUT CURT's PERMISSION FIRST.
Ye' can tek ehway muh sarvous mahnyule bet ya 'canna tek muh frrrreeeedddommmm!

This has been discussed before Greg. We are here to help troubleshoot to which board may be to culprit. After that they get sent to Curt. If Curt goes out of business, this site goes away. Then there is no help.
As far as setup and adjustment, have at it all you want....
Its not specified as a forum rule but its an implied request...
Why do you think there are almost no service manuals posted? And service manual links have been deleted. And requests denied.

mac...the times they are a changing. Curt seems to be aware of that given his efforts to work on more flat panels and other diversification. With all the pj's being parted out lately it isn't cost effective to have a board repaired but that in itself isn't anything new. People have always known 'a guy' who can get a board for less than repair costs or they get a PM from a non tech to buy from them.
I won't try and speak for Curt but I think even HE is selling more parts n pieces than pj's lately. Service dollars go down on fading technology and then starts to come back up again as the product gets older...then it's a specialty only performed by a select few. If that's where this technology is at now then I side with you. I don't want to hurt Curt in any way shape or form. BUT...that means the rest of should be allowed to evolve and that means the need for a restricted room inside the site to do what WE do.
At the other site most of us came from you had to go to the underground for information. This site was supposed to fly in the face of that ideology. I'd hate to think it's come full circle.
If this site depends on eeking out the last service dollars a CRT pj can give up...then we might as well start packing the good china now because that time is here IMO. Only hardcore stalwarts like us pay to use this site. You haven't noticed the rash of Guests posting their name or some other crap 5 times just to get around the rules? 
Who in their right minds except the insane regulars would even CONSIDER trying to make their projectors conform to the new 3D standards yet there is considerable talk here lately on just that subject? The complexities of that (3D CRT pj's) alone will weed out the non believers and posers as they jump on a sub $3K Samsung 3D compliant flat panel display. And then their pj's will be parted out for the rest of us vultures to absorb...which will hurt Curts repair business. So should we then expect restrictions on parts sales when that time comes? (I personally think that time is already here given the large number of working pj's being gutted for profit).
Proverbial can of worms for sure but I'll go with the flow when Curt makes a ruling. 
Apologies go to Paul for once again hijacking his thread.

The only thing I will comment on Gerg is that when those who choose to buy a used board over a repair from Curt, have on many occasions ended up with another bad board or it failed not long after words, and ended up seeing Curt in the long run. And even if it was someone with no electronics knowledge to do it themselves, if they had the specific repair info they could take their board to the local repair shop with that info and again sidestep curt.
As far as a sub forum for those who only want to do the repair themselves, my only thought is this. If you really know how to fix electronics then all you need is a manual and a few items. (Edit: actually a manual is not needed either.) But really, we already have a sub forum. Its called PM or email and there are a few here more then willing to help via that avenue.
Plus if you buy a board from Curt is has been properly repaired and tested.
I dont think Curt is looking for repair business from the regulars here. Its the other visitors.

No problems Greg. I think this thread is done anyway. Clearly I have it to the module level, so I will respect the wishes and not post publicly further on the module details. I'll just post back when I got it repaired to bring it to closure.

I considered that mac but I'd bet Curts 'name' hasn't made one difference to those that think these things are easy and just anybody can work on them. They change their tunes once the sparks start flying tho! THEN Curt has the bulk of them forever. A percentage will 'get over it' and move on to other technology and a very few will stick with it until they can do a little for themselves.

But...but...you're not replying to my earilier text regarding drawing traffic. This site is now MORE than just about whether Curt eats Hamburger Helper three times a week or eats steak and lobster all 7. We have a fairly good sized vendor roster now, including site funding via Yahoo purchases; and the only way to feed those vendors is to provide new traffic. Google probably accounts for a huge number of the 10K unique visitors a month as discussed in another thread.
Plus if you buy a board from Curt is has been properly repaired and tested.
Hear hear. That's a huge plus. I've not purchased alot from Curt...not one big dollar item at all, but when I get in a position to move up to a 9" (soon!) I'll buy it from Curt (unless an INSANE deal falls in my lap...yeah right). In my experience Curt is one of the last holdouts for perpetual support on products he's sold. The man almost has no time limit on some things. Very commendable. I dont think Curt is looking for repair business from the regulars here. Its the other visitors.

See previous comment. |
It has to be a double edged sword for him...kinda like planting a rose bush in a mound of $hit. 
I hear ya tho mac. We'll see how Curt weighs in on this. Odds are good he's already read this anyway.  BTW...I sometimes spell my name Gerg too so I'll answer to it...along with Gary, Craig, Rick, Bob....
