Hello all,
I just tried to power it up today and got this error message. number 67 vertical stop. the unit has 3 hours on it. any ideas on what would be causing this?

Denver

From the service manual

67 orange v. stop

This protect works when the vertical deflection is inactivated. In most cases inspection of the DF board will solve the problem.




I dont know what you are going to see on the DF board but maybe it is loose and needs reseating or the connectors reconnected.

That would be an excellent start. Great advice.

Cliff

Thanks for the advice. I removed the DF board and reseated it along with the 3 connectors. Still the same problem.

Ok, check all connectors on the three boards around it (on each side of the green tube) and remove and reseat all connectors, then take the back of the projector apart and remove and reseat all connectors on all boards in the back and report back.

If the PJ does not fire up, you have issues.

Your only "easy" option at this point is to do a "hard" reset to the eprom. I've seen both succeed.

Cliff

will do. If I do a hard reset, what is entailed?

Denver

Everything reseated and replugged in. Still the same thing.

I spoke with Ken earlier today. Since I did a rough calibration, I may have put the image off the raster. I centered the image well within the usable area as I was not looking for perfect cause he was coming out in 2 weeks to do a full calibration.

So I'm thinking a hard reset. I've never had to do one, any help would be great.

Denver

Should you wait for Ken? :rolleyes:

Denver, PM me your email address and I'll send you the service manual that describes the reset. I couldn't imagine your PJ has a bad board with only 3 hours on it. You did take the rear cage apart and remove all 4 boards from the back of the projector and check them right?

I've also seen it when you use too much adjustment on focus and geometry causing the PJ to shut down with error.

I'm off to work, but will send the manual tonight. Does anyone in the meantime have a link?

Cliff

Clarence had it hosted on his site. I'll see if I can find it. Do a search on Clarence / G90 on forum you should see it.

Question:
Is your G90 a new, just out of the box projector, or an older machine that has had a hard reboot?
One thing to try is to remove the bnc connector board at the back of the unit. The lower board has a series of small switches at the back center - easily within reach of nimble fingers. Click the switch closest to the back to the right. Start up your machine. This will place it in factory mode, and will bypass any wrong adjustments you might have made.
Make adjustments, and once happy, flip the same switch back on. The changes will be written to your ram chip. You should see a 38 on the error board. 90 seconds or so later, turn the system back on and all should be forgiven.

The unit was brand new on box. I got it last July, and just now got around to firing it up.

I tried what you suggested. First I powered all the way off. Then flipped dip switch number 1. Turned on. Then powered up by the remote. I still get error 67.

Thanks Clarence. I'm going over it now

Denver

I have tried what is outlined in 5-11sm. I am unable to get into factory mode. It still shows a error 67. I have reseated the DF board again along with the 3 connectors on the board.

How is a Hard reset performed as I'm not seeing it in the SM.

Denver

I need to reload the firmware. I am unable to detect the pj no matter what setting I use. I am using a belkin null modem cable from my laptop.

Denver

I am using a cable is a db9 & db25 female to female connector. I am going out now to buy a straight db9 to db9 null modem cable.

Everytime I press find device I get error 18 on the pj.



Denver

Cliff and Arli (bomrat) ran into problems using a null modem cable to reload/update the G90 firmware. Check with them to see if there are any special wire assignments.

Same with Lumagen and Leeza... I can never remember who uses a straight null modem and who uses a special pin layout.

G90 has a special pinout Denver. It's listed in the service manual.

Cliff

Ok thanks Clarence.

I got a db9f - db9f rs232 null modem cable. My computer settings are at 38400 data bits 8, parity none, stop bits 1, and flow control none. I also set the Pjupdate to 38400 and com 1.

Now I get a light flash from the y board far right and then nothing.

Any other settings on the computer or Pjupdate i get an 18 error code.

Denver

Ok I found the pin assignments in the Protocal Manual. I am thoroughly confused. How do I change the pins assignments of the connector that I have.
I am trying to upload from my laptop.

Denver

I am going to REALLY suggest that what you're doing is unnecessary and you might screw up more than what the set is right now.

(this coming from someone that's had ONE G90 in for repair and couldn't fix it, keep that in mind).

Remember that electronics seems to usually either fail right away or not for many thousands of hours. In your case it seems to be something that went bad right out of the box. I'm guessing you have a plain and simple V board failure. It happens. Unfortunately it's happened to you.

Two suggestions: No one other than JohnWman in France has a G90 as a working (sort of) chassis. I'm sure he can work on it.

Otherwise phone Sony and see if they still have a V board in stock. I doubt it, but maybe you'll luck out.

You _could_ send the board to me, and I can test/replace all common problematic parts on the board. I do lots of board level work on other sets with great success.

Is this set not under warranty? If you bought it last July, didn't it have a 1 year warranty on it?

(ok, there's 4 suggestions....:)

I spoke with Tim Dale(The guy I bought if from) last night. He got it around June of 06. He is going to call FH/Sony Monday to see what if any warranty is still available. Hopefully we can get this thing figured out.

Denver

Hello guys. I called Sony Broadcast today and spoke with 2 techs. They both told me to call the LA service office and ship the entier unit to them.

Then Henry at FH emailed me back with Vinh Vo's contact info. He's the engineer for the broadcast division. I must say Vinh has been great. Within 2 minutes he had my new firmware loaded without a hitch. Unfortunatly I had to leave and I still have the error 67. I have left a message with him as I would rather ship him boards then the entire unit.

There was no need to modify the cable. All I had to do was go into the emergency mode of the software. I was using an RS232 Cross cable.

Denver

I missed this thread Denver, Sorry...

I fact I was able to let you know how to reload FW using the emergency mode of PJ Update. This would avoid you wasted time !

For your error 67, I would recomand swapping the DF board with a known working one to ensure that you've located the source of the defect. Then, one EE can try to repair the board at components level ...

John

Since the unit is still under warrenty, I sent Sont the YA and the DF board. They got them yesterday and are working on them now.
