Heating resistorR161 and r162, check for possible leakage in transistor q156. * 27Aug97 anc *.
PHILIPS54VP51C
Appears in the / menu, however, without an image.Check transcorder with possible cold welds, or defective. *20Aug97 anc*.
PHILIPS54PP700A
Without tune.Check connection cable a402 pin 1 (+130v). * 16Oct97 anc*.
PHILIPS54PP700A
Frame sparkling with expanding "bloom".Verificar integrado ic402 (cold side). * 13out98 alan *.
PHILIPS53UP72G
Vertical closing intermittent.Check welding of ic552 and ic550. * 29Aug96 anc *.
PHILIPS53UP72G
Voltages below the specified (vo, +b,..)+15 e 15, verificar ic110 (n5532). * 25set97 anc *.
PHILIPS53UP72G
Voltage oscillating (pulsating).Power supply (+5v stb), possible short on the +5 line, see d305 and d306 with escape. * 16Aug96 anc *. check integrated ic401 (6126642). * 25Sep97 anc *.

PHILIPS53UP72G
Dark "black" screen (see also bril4).Check capacitor c618 (.01) with leakage, pin 58 ic600. * 15Aug96 anc *. driven by the vertical, see r585 (20k). * 09Oct96 anc *. resistor r301 (0.27Û) open. * 05nov96 anc *. check integrated IC600 (TA8845AN). *27Aug97 anc*. case fi
PHILIPS53UP72G
Blue fabricResistor r301 (0.27Û) open, occurs when switching on and then screen goes dark. * 05nov96 anc *. blue screen with dos and sound, check ic304 (ssp board). *17Sep98 h.desk*
PHILIPS53UP72G
Sound has a whistling or buzzing sound.Check coil l804. *05nov96 anc*.
PHILIPS53UP72G
So fica em stand by (power off).Check crystal y301 (12mhz), does not fluctuate with level satisfactory, measure µp pin 3 (2.4v) if this is not available reference the µp will not activate "power on". *27Aug97 anc*.
PHILIPS53UP72G
No voltage (vo, +b, hvt, etc.).+130, check if when connecting pin 52 of the micro ic300 it goes to 5 to 0v, if it doesn't change, check the computer. * 16Aug96 anc *. no voltage see f402, open case possible short in q802. * 16Aug96 anc *. +130, check integrated IC401 (6126642). *
PHILIPS53UP72G
No horizontal oscillator pulse.Measure pin 8 of IC900, if it is above 4.5v, there is possibility of being triggered by "h&v deflection failsafe" (q501); check that there is no broken track (+170vp) close to t900. * 04Sep97 anc *.
PHILIPS53UP72G
Light spots with dark background. starfieldPossibility of IC600 (TA8845AN). *27Aug97 anc*.
PHILIPS53UP72G
It doesn't work (it stays off).The power supply only starts if there is a change of 5v from "off" to 0v to "on" at pin 52 of IC300, if it has a fixed 1.2v see the micro. * 16Aug96 anc *. capacitor c616 (.33uf) shorted to +12v on the small board. * 05nov96 anc *. check crystal y301
PHILIPS53UP72G
"cross" [+] does not appear in service conv mode.Check j307 open. * 25Sep97 anc *.
PHILIPS53UP72G
Does not adjust with. red (-) "hot. red".Check resistor r380 (0.33Û) changed. * 16Sep97 anc *.
PHILIPS53UP72G
Horizontal lines (bottom or top).With a gray screen, check for a possible defect on the panel Transcorder (PAL/NTSC). * 15Aug96 BC *. presents risk and no dos, see ic600 (ta8845an). * 27Aug97 anc*.
PHILIPS53UP72G
Dos/menu - running vertically.Check integrated ic300 on "small" panel. * 03mar97 anc.
