Coby TF-DVD7100 7" portable flat screen...keep getting "Wrong Disc" Error
I have seen this problem on several Yamada & Xoro brand DVD players. If you remove the lid after powering down with the disc tray closed and a disc in it you may well find the ribbon cable to the read head is rubbing on the disc. The ribbon cable is held to the base of the box by a sticky pad under a 45 degree bend in it and a piece of sticky tape !!!. Power up unit, open disk tray, power it down, retape cable to base securely with small strips of duct or gaffer tape (using tweezers helps) and hey presto it will work again. The cable rubbing slows the disk spin speed hence "data read error" unit assumes "bad/faulty/wrong type of disk". All that technology screwed up by using a cheap bit of tape in the factory assembly, amazing eh !.
