Hello colleague: ... according to chassis q. mentions .... the voltage obtained from 4.3v at the emitter of the Q701 is low ... it should be at 5v ... that voltage drop at the emitter of the Q701 may be q. the l701 is damaged or you can also have damage to the eeprom .... do the following ... remove the Q402 salt-hor- from the board ... then lift the connection of the 4,3v q, go to pin22 of the lc701 and measure whether the voltage at the emitter of the Q701 went to 5v ... if the voltage continues at 4.3v raises the voltage q, goes to pin8 of the eeprom ... and measures back at the emitter of the Q701 and see if the 5v are restored .... the suggested is x what, says q. the lc701 is very hot ... in reality the lc701 should not heat up .... if when raising the voltage on pin22 of the lc701 the voltage on the emitter of the Q701 at 5v ... may be, the lc701 may be damaged. ... keep in mind that the lc701 is the q. imparts the operating orders of tv ... if it is damaged there will be q, change it and prove ... ok .... greetings !!!
