How can I fix digital bathroom scales?

How can I separate the top and bottom plates? I need to solder the two wires back into the little plastic switch block which clips into te nderside of one corner

Bought a cheap scale under 10 euros worked for a year ,must say good ,but than it stops working.Checked battery ,2.75 volts ,still good.Well thing is dead so let's open it and dissect it.OK ,there is PCB board and LCD display,must remove display to see the chip, if there is any.And there he is ,usual Chinese crap,black epoxy spot on PCB,but hey,what's this there is one SMD 8pin chip.It's labeled 24C02,serial memory chip.But what is he doing here,this scale does not have any memory any buttons or programs.The only thing that comes to my mind is that this is counter ,and when he count down ,the scale will stop working.Please someone tell me I am wrong !

As a repair engineer for weighing machines, I can tell you the following. Most bathroom type scales purchased from high street outlets (including mail order etc..) are of poor quality and cannot be repaired when faulty. If you think they are expensive, a good set of medical personal scales should set you back around £300! They will be adjustable and calibrated if you buy them from a reputable scale company. These will be tested with known weights from the trading standards and should be adjusted yearly. Seriously, its a case of you get what you pay for! When cheaper scales breakdown, and they will, nothing can be done with them.
