Just installed a new G70 (171hrs) that I've been hoarding for a couple of years. Setup went absolutely perfect, with one exception. When I tried to enter Service mode to save data as service data, I could not enter service mode! By the way, I DO have status turned on (common mistake). When ever I hit enter to do the old (enter-enter-up-down-enter) , as soon as I hit enter, I get a display on the lower left that says (INDEX:0) or whatever index number is selected on the rotary dials. Then the rest of the sequence fails. I am completely stumped! Have had multiple G50s and G70s and never seen this problem. The old G70 that I replaced worked AOK for service menu. The only thing not standard on the G70 is have an early Moome HDMI card in the B input slot. I now have an absolutely gorgeous picture, but would like to be able to get to Service mode. On the menu, it now has a big red F at the top, where the big yellow S should be for service.
Any of you geniuses have any thought or solutions?

It sounds like you are somehow in FACTORY mode. Did you change any jumpers on the YA board?

I will look in the SM if I have time.

Did you have this projector in service mode before? You need to be in service mode to do most adjustments including focus and astig so you could not get to these on the remote without being is service or factory mode.

Try pressing the "sys set" button on the remote and let it do its thing for a minute.

I have never put a G70 in factory mode before and I can't find it documented. There must be a factory mode though to setup initial data at the factory. Do you have another G70 that you can compare to? What you might want to do is pull the YA boards out of a working G70 with a service mode and compare all of the dip switches on each YA board. The dip switches should be the same on both boards. If one or more is different on your G70 with the F menu document and switch the jumpers to match the good YA board.

Who had this projector before you? What is the history?

The OP's post is confusing to me... If he weren't able to get into Service Mode, he wouldn't have even been able to do any convergence.

Bought this G70 from a home theater outfit several years ago. They said it was ordered for a customer and never installed, given it shows only 170hrs, sounds right. They did mention that it was a B-stock unit. Perhaps that explains the possible FACTORY mode, as it was likely a return for service unit and may have been left in factory mode after their checkout.
I think you may be right on the big red F meaning FACTORY mode, seems logical. I'll have to look into that YA board thing. I do have the service manual also, so I need to do some reading.
But one thing, compared to my old tired 40k plus hours G70, this thing looks STUNNING in HD! But that old G70 served me well for ten odd years with very few problems. These things are built lika a tank.
Thanks for your input, let me know if you stumble on anything else.

It says factory refresh because 1 switch is for factory mode and 1 switch is for refresh of the main CPU. Other switches are for P73 and P74.

Oh, switch 1 is for factory mode...

Did you try doing a factory reset?

If nothing else, you can send me your YA/Yb boards here for testing or replacement if nothing else works. I do have spares.

VOILA!!! All is well, took a look at S100 on YB board and Dip 1 (Factory) and Dip 4 (PF74) were in the off position. Flipped them both, powered up, and everything is now normal. I'm sure this was a demo return or something and when Sony checked it out for resale as a B-stock, they forgot and left it in factory mode.
I have never had a basically new G70 (171hrs) before, and I am just stunned with the picture vibrance and quality. In the last 20yrs, I've struggled through used 1270, 1271, several Barcos, G50s and G70s, but never knew things could look so good!

Big thanks to all who responded to my plea for help and thanks to Curt for this forum!

Good

So did your old G70 have 40k hours on the original tubes? If so it must have been pretty dim compared to the new one!

Glad someone here could help, that's one I would have never figured out via email. Those are the worst, strange fingers in the set, mucking with stuff that they don't know about. Smile

Cheers!
