Title: Sharp C1 - Internal shots, anyone?
Post by: Dejah.Thoris on February 28, 2023, 11:32:46 pm
Looking for shots of the chassis if possible.  Top side, especially any identifying silkscreen markings.

Trying to help a friend (from afar, currently in storage until next month) in repairing their 14" C1.

The primary transformer isn't outputting any voltages (broken internally, yay), and I am hoping to find another Sharp era TV from which I can steal a transformer. 

Good news is that Sharp's manuals list the chassis right on the front page of the manual, so finding a donor should not be hard once I know what chassis is in the C1 itself.  It seems they used a lot of Sigma 7000 and 9000 chassis in that era, but I'm not too sure what's in the C1.

Any assistance at all would be appreciated!

I promise you they don't.  Ha.

Just bought one myself and will be using mine to help my friend fix theirs since no one here seems to know anything about them unfortunately.

So you'll still have a broken one after you take the transformer to make your friend's machine work? Again, let me know if you wanna get rid of it.

Chassis is PWBF2942CE

If you find a suitable donor, please let me know, as I'm still trying to get mine up and running  ;D

Not OP, but does your flyback transformer happen to have a part or model number on the side? Would be interested to know if the Sampo used the same as the C1.
