|
|
Well, I have my first G70 problem. Error code 35 comes up and the pj stops.
I was watching a movie tonight when I noticed how the red was sticking out of lines. I put up a test pattern and noticed that the red was out of focus. It was fine since I got the pj a month ago. I tried adjusting the focus mechanically and electronically to no avail. The electronic focus still would make it's adjustments, but it would still be very fuzzy at best.
I opened up the G70 and tried to re-seat the H and F boards. I have it ceiling mounted, so it's tough to keep them seated. However, even when I hold the two boards firmly in place and press the on button, error code 35 pops up and the G70 stops. The error code wouldn't come on until I tried to re-seat the boards. Any idea what to do? Maybe I should clean the board contacts?
An error code 10 also comes up sometimes.

Yes!!!!!
(I can't say it's the same as your problem)
But ,.... DraganM's Eboard came and fixed my PJ 100%!!!! I could not be happier.
The church wanted to come view a movie here tomorrow and I was about to call and cancel but the board came 2 days early.
THANK YOU!!!!!!
-Brian

Good for you Brian! Must be a relief!
Which board is the E-board?

it's the big upright one between the Blue and Green tubes= Horizontal deflection

Okay, I know which board that is. I actually already re-seated that one, but have not cleaned the contacts yet. Will try that first.

Well, I tried cleaning the contacts and it still shows error code 35. However, it also shows error code 10. Not sure what that one is.
The issue that occurred that led me to re-seating boards was the red being out of focus. Would that E-board cause that problem?
Sounds like Brian solved his error code 35 with a replacement E-board. Any body have an extra one they want to get rid of?

These board do fail, and the parts are expensive when they do. It's a flat rate of $250 incl return shipping to repair your board. Let me know, they aren't easy to come by.

One more thing. After reading about others who had this issue, could running the raster really wide cause strain to the E-board (not over the edge, but pretty close)? I am trying to maximize phosphor usage, but may be straining the H-Def electronics.

I think running the raster wide could cause additional strain on the E-board.
I run it nearly to the limit and I may be close to 8% closer than the correct throw distance ... My E-Board just recently died. Today I moved the pj back a little but not much. It wasn't easy to move given the way I have it mounted.

It might be ironic if the raster size is what is causing the E-board to fail. Here we are trying to maximize raster size, but causing a board to fail because of it. Maybe there's a good reason for the manufacturer's recommended throw distance.

Unless you're running the raster way off the tube, I really don't think a wide raster will, by itself, cause the E board to fail - although this may compound any problem inherent in a projector that is possibly 11 years old (assuming 1997 production).
There are some 20,000+ electrical parts in this machine - all it takes is any one of these to fail. I can't think of any other single 'appliance' in my home with as many discreet parts as this PJ. The B board alone is populated with more components than every PC in my house, combined.

I wouldn't be to swift to dismiss this. Usually on an analog power circuit like this you have 2 amps running in a push/pull configuration. The higher the voltage swing across them the greater laod on the capacitors and transistors. So there's a few things that will make this board work harder, higher scan rates and higher resolution are obvious ones but also how far you phsically have to delfect that beam to the left and right will almost certainly contribute to the heat being generated.
