good afternoon check voltages in the cathodes of the three colors can be exhausted tube, if any of them varies a lot compared to the others is exhausted tube would have to do the cathode test to discard the CRT, another test entering service mode and check If memory shows errors. Regards.

Hello colleague: ... if it is the chassis L03.1UAA, it measures on pin 10 of the fli-bak which voltage you have ... it measures if the tuner receives the 5v of power supply pin7 and the 33v of tuning pin9 ... it measures q, voltage you have on pin36 of tda93xx ... if you don't have tension on pin10 of fli-bak check the R3442 and 3441 of 120kohm c / u ... they are connected in series between the voltage of 160v and pin10 of fli-bak ... see if the jungle receives tda93xx the feeding tensions ... greetings!
