(VSCAN). I DID NOT EXPAND ONLY I HAD -74V NEGATIVES WHEN THE SPECIFICATIONS SAY THAT I SHOULD STAR FOR -195V TO EXIT THE SCREEN AND GENERATE LIGHTING, THEN TO DO MUCH TESTS AND CLEAN THE FLEX THAT COME FROM THE LOGIC CARD OF THE MECHANICALS. MAKE BOTH CARDS WORK AND THE DISPLAY LIGHTED.CORRECTLY.STARTING TO GENERATE VIDEO ... THEN CALIBRATE ALL THE POTENTIOMETERS AND VOLTAGES..THE DETAIL FOR WHICH I CONSILT .ES BECAUSE ..... I START BUT ONLY WITH THE HALF OF THE RIGHT DISPLAY ... AND THE LEFT HALF IS ALWAYS BLACK ... BUT IT HAS TWO VERY VERY RED VERTICAL STRIPES AND A GREEN RQYITA ON THE EDGE WHERE THE SCREEN IT IS DIVIDED IN TWO ... THE REASON IS TO SEE IF ANY TUBE A PROBLEM IF MILAR AND IF I ACHIEVE.

Friend check the buffer on the side that does not have lighting, oh take into account that the plasmas are already obsolete since 2014, greetings.

EM FINALLY THE PANEL WAS BAD ... I HAD CHIPS IN SHORT ... SO YOU HAVE TO LOOK FOR NEW PANEL PÑASMA PA CHANGE IT LEW NOTICE HOW THE FOLLOW-UP REMAINS.

Friend, I have one like that ... what did it look like? I know if it's the panel that's bad.
