The Nikkei Electronics Breakdown Team acquired Hitachi Ltd's "Wooo UT series" ultrathin LCD TV (See related article). Instead of taking the long way around by following the manual as we often do, we went straight to the breakdown.
It was very easy to disassemble the TV. It might have been because we had just taken apart an OLED TV only several days before (See related article). Unlike the OLED TV, with which we were careful not to damage the display, we quickly removed the screws from the LCD TV one after another without hesitation.
After detaching the stand that holds the display, we attempted to remove the chassis mounted on the rear side of the display. The chassis was entirely flat, with the only exception being the air intake and discharge holes on its top and bottom.
Finished removing all the screws, we finally removed the chassis.
"It's so simple," an engineer said despite himself.
Appearing before us was a variety of substrates tidily mounted on the rear surface of the LCD panel module. It certainly looked very simple, probably because we could not directly see most of the substrates due to the shields covering them.
The heights of these attached substrates were surprisingly even. Measuring from the surface of the base panel module, the substrates were lined up at a height of about 13.6mm. We estimated the heights of the other substrates were coordinated with that of the power supply substrate, the thickest component among the embedded substrates.
