(2)负载加重也是损坏IC601的一个重要方面,可串入500mA～1A的直流电流表在+B电路,如果电流超过500mA以上,应检查行扫描电路(行负载短路)。若+B升高过高,可更换IC601或在IC601的"!脚接分压电阻进行微调。若电压不稳,可检查由C607(0.082μF/100V)、D604、R603(8.2Ω/0.5W)组成的
(2) The heavy load is also an important aspect of IC601 damage. The DC ammeter with 500mA ~ 1A can be connected in the + B circuit. If the current exceeds 500mA, the line scan circuit (line load short circuit) should be checked. If the + B is too high, replace the IC601 or fine-tune the voltage divider on the IC601 pin. If the voltage is not stable, check if the voltage is increased by C607 (0.082μF / 100V), D604, R603 (8.2Ω / 0.5 W)
