LCD Burn in?

If you're like me, you were probably told at one time or another the LCD monitors do not suffer from the same "burn in" problems that plagued CRT monitors.  This was a huge issue, so huge in fact that it seemed that nothing could outsell the After Dark Screen Savers Series and perhaps nothing did.   (Geez, that brought back some memories...Flying toasters, Mowing Man, Fish...cool.) 

There's a good chance that the non-burn in factor was probably a large part of the justification to put a sizeable dent in your wallet when this technology was new. 

But is it true?  Sort of.  There is a similar problem with LCD monitors called image persistance.  Read about Dave's experience with his new Sun Ray 170 (which actually has a high quality LCD) and image persistance, and more importantly how he fixed it.

Thin Guy, Dave performed a 'workaround' on his Sun Ray 170. I believe he realized 'capacitance storage' within this product. A 'permanent' solution is as follows, 1) Include of an 'on-off' switch which severs primary power while providing an isolated 'ground' lead if not provided. 2) Review and/or modification to the product 'ground' circuit. (a.k.a. LCD power supply) 3) A manufacturing defect within this specific item, NOT typical within all Sun Ray 170 LCD's. 4) Dave's facilities has a 'ground' fault. Corrected a similar problem for MEMCO in 1995. (An 'unreliable' ground circuit for IGBT components was identified. Burnt (30) in the field BEFORE they tested my hypothesis. Now sold as the 'XMT 304'.)
