PHILIPSL01.1L AC 29PT4631-25PT5531-29PT4640
It loses time when it goes to stand by. -Check capacitor 2351 (low capacity).
PHILIPSL01.1L AC 29PT4631-25PT5531-29PT4640
Has no colors -Check crystal: pal m crystal abc f226 3, 57611 18sp; NTSC Crystal ABC C 3, 579545 18SP, used with "TDA8360 N5".
PHILIPSL01.1L AC 29PT4631-25PT5531-29PT4640
It has no date, clock,Check capacitor 2111.
PHILIPSL01.1L AC 29PT4631-25PT5531-29PT4640
Does not work (it remains switched off). -Measure voltage on the collector of the transistor 7502, if it is high, it is possible that the integrated 7200 is defective.
PHILIPSL01.1L AC 29PT4631-25PT5531-29PT4640
Does not open vertically -Check leak capacitor 2407.
PHILIPSL01.1L AC 29PT4631-25PT5531-29PT4640
It works intermittently (see slide2). -C111 flashing.
PHILIPSL01.1L AC 29PT4631-25PT5531-29PT4640
With dark band in the center (i).R3229 (1m) pin 42 of the bimos causes stains in the drizzle and intermittent vertical closure.
PHILIPSL01.1L AC 29PT4631-25PT5531-29PT4640
With dark band in the center (i).R3501 (power driver horiz.) causes beam or bending of the beam in the middle of the screen.
PHILIPSL01.1L AC 29PT4631-25PT5531-29PT4640
With vertical bar(s) or stripes -C2233 (r-y signal) causes red bars or spots on the side of the screen after heating.
PHILIPSL01.1L AC 29PT4631-25PT5531-29PT4640
Blurred or deformed characters. -Check capacitor 2938 (120pf), depending on the location it can be removed.
