The problem has changed a bit. Sometimes there is a start. calibrated perfectly. and with warming up for about 5-10-15 minutes, the input test signal is turned off. The measurement symbols remain on the screen. Re - power on- indicates the chip 160-3493-00. startup is unstable. This is a definite problem. The output transistors heat up to no more than 53 Celsius. Please advise who could solve this problem. Added a photo (please see).
