Asunto: [OT] Oscilloscope LCD replacement


Dear All,


My Tektronix THS730A's LCD screen got damaged. It has an irregularly
shaped region near the center of the screen that is faint.
If I adjust the contrast then I can see the image in that region, but
then the undamaged area gets too dark to be seen.
It is clearly something related to the polarizing filters because I can
see the stain even with the scope turned off. Besides, the stain contour
does not follow the pixel's borders (it is continuous, not serrated).

Would it be possible to replace just the polarizing filters? If not,
where can I find a replacement LCD panel?
This model is long out of production, I think Tektronix doesn't stock
its parts anymore. Here in Brazil there is no more official Tektronix
representatives anyway, and the guys that have the part in stock charge
almost US$1,000.00.

I tried to buy a THS720A in e-Bay to use just the LCD panel but was outbid.
I appreciate any suggestions.

Best regards,

Isaac
