Question about Dell Axim X50v Pocket PC
I did a hard reset and when my Dell came back to life it to me to the "Align Screen" page. No matter how many times I hit that "X" sign and make it move around the screen - nothing happens. What do I do next?

OK. This is not for the mechanically un-inclined. The short answer is that the touch screen membrane is separating from the display panel and MAY be fixable by inserting pieces of rubberized foam. The following is a post of mine in another forum www.mobilitysite.com.
I have recently exhaused my patience with the ever-changing screencalibration and decided no matter what, I was going to resolve thesituation or destroy this useless handwarmer in the process. My unit isoff warranty so with little to lose I charged ahead.
Having tried most of the suggested solutions on the forum with limitedand intermittent success, I got out my golden screwdriver and poppedopen my X50.
Using a jewellers screwdriver (xActo would work as well or better) Iremoved the adhesive covers over the case screws. I had a very smalltorx (#5 or 6 I believe) screwdriver purchased from an online cellular phone parts outlet(couple of bucks) and it easily removed the 4 screws (remove batteryfirst!).
I slid a thumbnail under the upper left (or right) corner (the cover isjointed between the silver and black on the edge) and pried the caseslightly open to verify it would part and slowly worked it down theside and the case. It popped off suddenly and without incident (and noshedding of parts/springs/buttons...etc.).
Underneath the entire display plate and touch screen appeared in goodcondition. I gently cleaned the face and edges of the plate where thecontact strips for the touch screen were clearly apparent. Using myPDA stylus, I pressed gently but firmly on the screen over the contactstrips and ran the stylus around the perimeter of the screen plate,ensuring that solid contact was made to the strips. They did not appearto have separated or delaminated in any way but due to the otherexperiences of forum members I expected there was some issue of loss ofcontact. My troubles incidentally began after a waist-high drop of theunit while in its case.
After the "burnishing" of the edge of the plate, I deftly cut twonarrow strips of the "frosted" scotch tape variety and using the tip ofthe jewellers screwdriver and my fingers, placed them directly on thedisplay plate over the top of the contact strips at the top and bottomedges. I did not do the left/right edges as I had never observed theproblem on vertically drawn lines. The tape was applied to "encourage"more pressure and better contact of the touch screen with the top andbottom contact strips.
Re-assembly of the case was not complicated, but pay attention to thespeaker bud and ensure that it returns to the flange in which it isheld as you mate the silver cover plate with the black case. Replacescrews and torque gently but firmly.
I actually tested my unit prior to re-assembly and the EKG pattern Iused to get from drawing a horizontal line across the top of the screenwas completely resolved.
So far it is working without any problems. If your screwdriver is notgolden (or you are faint of heart) locate a friend who is mechanicallyinclined with small devices to perform the surgery. I did not take anyphotos of the surgery as the patient expressed confidentialityissues...sorry. Maybe someone else can snap a few if they try the fix.
This worked for awhile but after about a year the problem returned...my next solution/post...
OK...latest developments...the problem has returned somewhat.
I disassembled the case again and "burnished" gently the touch screendirectly above the conductive traces around the edges of the membrane.Again, the problem resolved itself. My take is that there is some sortof delamination of the screen with the conductive paths that ishappening.
Today's therapy for the problem was to take some 3/8" round,adhesive-backed, soft foam rubber pads (the kind you might buy to puton the bottom of a book-end to keep it from scratching the bookshelfetc.), and cut into small 1/16" wide strips. I placed these strips overthe top of the touch screen membrane, directly over the conductivetrace. I did not do the same on the bottom as the problem has alwaysbeen observed (and corrected) with the top strip. You could use largerdiameter pads to simplify the process but the essential issue is theymust be "VERY" soft and spongy (these are really unique in thatcharacteristic). I believe I obtained them from Lowe's. Anyway...if youuse something that is not really spongy, you will likely cause the caseto bulge/deform from the pressure (or worse yet, crack the LCD from thepressure). The thickness of the pads I have is around 1/16".
You could conceivably use a number of other materials to accomplish thesame effect...but you essentially need to use something that willsquish down without exerting too much pressure (soft/spongy) and yetmaintain that pressure in the long term (can't be something that willpermanently deform). Soft foam weatherstrip might be a candidate butmust be trimmed down to a thin height.
The problem is once again resolved. I do note a very slight curve tothe case above the top edge of the screen but it's not excessive anddoes not appear to deform the display (confirm this by viewingreflection distortion of the screen surface). Over time as the foamrelaxes somewhat, this should diminish, yet gentle pressure shouldcontinue to be exerted on the membrane.
Anyway...that's the latest from the "out of warranty" repair attempts.
