Very good, but pay attention to the contacts
Substitution of the LCD+Touch assembly was quite straightforward, but I admit to be an experienced repair guy. The only thing I needed to fix on the new part was one of the touch screen connectors: a "Quality Check" mark was stamped right on the gold plated contacts, right where it's supposed NOT to be. Cleaning with IPA easily fixed the problem; luckily I discovered it before putting everything back together with tape! General advice: perform a functional check BEFORE reassembly. Once everything was fixed, the final result was as good as new.
Digitizer & LCD screen combined
Initially I had a cracked digitizer but the tablet was still working. I decided to a DIY replacment of the digitizer £25 but found it difficult to replace and subsequently cracked the LCD screen - oops!
Ordered a complete unit it, being digitiser & LC, it came after a while but undamaged and well packed although at £135 not cheap. I fitted the unit but it did not work? I fiddled with it but one of the securing tabs that hold the wiring tabs to the main board eventually refused to lock. It now lies in a box and I am currently mulling over my next move seeing that a repair may bring the total cost for repair close to that of a new Tab.
I put my failure down to inexperience and my advice is to put your Tab for repair with someone who has experience, or chuck it in the bin and buy a new one!
