This time we will try to fight against planned malfunctions, by bringing back to life our favourite LCD.
Step 1: LCD tango down
Placing heat-sensitive electrolyte capacitor near elements which are emitting a LOT OF energy by heat is one of the most common method to reduce life time of product. This causes faster loose of capacitance and, in effect, failure of element. And this, exactly, happens to me.
Step 2: Disassembling LCD
Use your engineer sixth sense to dismantle EMC shields.
When You get to cables, make photo of all connectors, it will be big help in assembling. When photos are done, You can disconnect all connectors.
When cables were disconnected, i could take out box with PCBs. Locating power supply is easy: look for the board with soldered power socket.
