Model 100/HX-20 LCD Display Problems

[Marvin Johnston]

In getting ready for VCFMW, I started looking at some model 100s and 
HX-20 notebook computers. Most of them have blank LCD displays, so I 
figured there might be a common problem.

So far, I've found leaky electrolytics on all of them, usually 10 uF, 
but there are some others with all of them so far associated with the 
LCD power supplies. The Epsons seem less prone to this than the model 
100s, but both have the problem.

Has anyone that has done repair work on these computers found the major 
problem to be leaky capacitors?

My gut reaction at this point is to just replace all of the 
electrolytics. Does this sound like a reasonable longer term approach 
rather than just replacing the obvious leaky ones?
