It started with the red on my G70 being out of focus. I tried re-seating boards, then an error 35 code came up. I got a replacement E-board and installed it. Error code was gone, but I could not adjust the raster horizontally.

I then put the original board back in and pushed it in firmly until it clicked. At that point I realized that I didn't push it in to that point when I was getting the error 35 code. In other words, there was nothing wrong with my E-board.

So now the G70 fires up fine with my original E-board. Now another problem. The raster is too small horizontally, even when maxed out. I have also lost horizontal centering control. It seems like the replacement E-board has messed something up. Also, the pj will go to error 35 unless a source is inputting 720p or 1080p. It will have error 35 with 1080i or no source.

In addition, the original problem seems to be isolated to 1080i(red out of focus). 720p and 1080i look fine.

Talk about one problem snowballing into an avalanche!

Is there any hope for this G70?

If you get stuck, send me the convergence board along with both E boards. I'll repair them...

I agree. I do have a crt jinx. I was surprised that it was working for a month before any problems came up. That was a record!

Curt, I'll be in touch.

johnsmith....

You mention you can't get the raster big enough with size maxed out...

On the ebaord there is a variable resistor labeled H-Size.... With it you can alter the size of the maxed out Horizontal dimension.

Something may still be wrong with my G70... As you know I recenlty got the error 35 just like you and replaced the E board. Everything is fine now except for one problem.... With 1080p I can't make the horizontal size over say 180 or the pj shuts down with a code. Strangely... I can still make the image fit the screen by having the RGB size much larger than the internal test patterns but this problem is new.

????

If it wasn't so easy to work around it... I would really want it fixed.

THis is the problem with mixing and matching boards. SOme stuff is calibrated to the specific set. As with NECs and BArcos, I would not randomly go tweaking pots, especially with some transistors on the E board being upwards of $80 each from Sony.

I've suggested that he send me both E boards, the F board and the C board for testing. Sound like it's possible that either he's had multiple failures in the set in short order, or by working on one area of the set, something else got disturbed on another board. The G70s are generally pretty reliable, it's strange that this has happened in one set more or less all at the same time.

Hi,

Well,... like I mentioned above... My g70 had a bug of sorts since replacing my E-board only with 1080p. I couldn't get the horizontal size above about 230 without the pj shutting down.

I went around it with the RGB size controls but having something wrong was like having an itch I couldn't scratch. So I decided to do a full reset. (Not the one with the dip switch but the one where you hold down reset and enter full reset mode.) Anyway... I let it rip then shut it down. I restarted it and it's fine now. I'll have to re-do EM- Focus,.. Geometry,... and Convergence but ... I already did a bit and it's going well.

I think after swapping a board... a system reset may help... It certainly seems to have solved a bug in my case.

Thanks again for the E board.

John, I see your parting out your G70 on videogon!! So what's next? Going to give the Marquee another try or going digital?

I guess I couldn't hide from you, LOL!

I think me and crt's just don't get along very well. I can say that my wife is very happy about the end of the G70.

I'm sort of stuck figuring out what my next move will be. I was leaning towards getting a cheap plasma from Panasonic to hold me over until digitals get even cheaper and better.

If I could have gone back in time, would I have gone the Marquee route? I just really wanted to get a liquid coupled pj. I didn't imagine that the G70 would give me problems so quickly. Hind sight is always 20/20 but I don't think I could have gotten another air coupled crt. Just my taste.

Used RS1's are around 2k now. I don't want to pay that much right now. I think the diminutive plasma will have to do for now...sigh.

Sorry to hear that. Sometime CRT's just aren't for every situation. If you had a dedicated room then it be a different story.

That would be awesome, but I only have a 2 bedroom condo around 1,100 sq ft so the living room is the best option.

If I had a dedicated room, that would be incredible. I would definitely paint everything dark and I wouldn't need a retro-reflective screen either.

I think with digitals the room reflections are not as noticeable since the image is brighter and digitals especially dlp have higher ansi contrast. Yet, even with a very good digital pj, I put up the ansi checkerboard pattern and the blacks were pretty washed out.

I've seen a dedicated home theater room once. It had a crt, an XG. It was a breathtaking experience. I ended up buying the projector from that person. It never looked the same in my living room for obvious reasons.

That's why I am leaning towards getting a plasma. Room reflections won't affect it as much. I also thought about getting a used crt rear projection tv, but the sharpness just wouldn't be their with 7" ES focus tubes. I've owned 3 in the past. Probably the best option for crt in my living room, but tough to compete with the ansi contrast and resolution of a plasma.

There are some Barco retro 808 units, Curt had a few of them a while ago. If I remember correctly they were also LC models.
