There are several ways in which this problem can be resolved in principle. The easiest but the most expensive is to buy new watches and replace them. The original clock will cost about one and a half thousand roubles.
It is possible to go another way-to read the hours and replace the diode (CD 243 F), which is why the image disappears. To dismantle the clock, you need to put up a coaster and twist two smores behind them. Then, click on the central console panels, unplug the clock slot. The clock is attached to the console at the rear with two carroes. You can pull them out, you can pull out the clock.
The body needs to be addressed. It consists of two parts: two clips from each side. Total LEDs are in hours of four. We need the one marked as "D2". It's going backwards.
