Translation of the power supply to operate normally the command IRD_PSU_ON NOT_STBY 23 output connector P2 and elements Q851 and PC802. It was found that a change in the control voltage (simulation commands ON OFF) to 23 pin connector that has no bearing on the mode power supply. From which it was concluded that it inoperative. Checking and replacing the control and stabilization of the output voltage, and finally, the PWM chip F9222L gave no results.

As a result of piecemeal check the power supply was installed faulty component - the transistor Q803 2SK2231Q, was part of the power supply unit IC801.

His replacement restore your TV (transistor had no direct breakdown, and calls with a significant drain on the new). It should be noted that the process of repair TVs Panasonic is somewhat different from other manufacturers to repair the TVwhich is associated with specific features of circuit design and used the element base. In the process of repair were used Service manual and schematic chassis GLP21 Memory contents use56, По поводу ремонта сюда Схема здесь думаю найдётся.

И на будущее - в заголовке отсутствовал вид аппарата. То есть телевизор (ТВ) Каково сопротивление между ножками проца 64,65,68 и корпусом. TE, тут такое дело все, конкретно на эту ревизию, кидали друг другу в личку прошивки. Те что бинарники лежат они на другие ревизии и соответственно не работают. Помогите если есть именно на мою, скиньте .
