HERE TODAY three models of Philips televisions and their traditional defects. This
content and others can be found in my new book that covers defects,
tricks and the way of service of televisions of this brand. I
recommend the purchase of this unit, as it helps the repair technician
to quickly identify problems on the bench. And for those who still don't
know my work, I also recommend the LCD Collection, which is currently
in 9 modules with a varied content to know the maintenance of these
televisions. .
42PFL5332
- When giving power, comes out of stand-by (blue led), but the screen does not light up (photo U202 coupler - source)
- Dark screen (change the electrolytic capacitors of the Inverter and check SF1 and SF2)
- Dark screen, led changes to blue with noise at the source (Change photo U202 coupler)
- Shutting down (Change capacitors of the Inverter and U202)
- Dark image in the center (U202)
- Burning the integrated oscillator of the Inverter, plus the transistors and filter capacitors
Solution:
replace the 6V8 zener diode that polarizes pin 28 of the inverter plate
oscillator IC and replace the 470 µF X 35V filter capacitors with
others of 1000 µF X 35V.
32PFL3322
- Dark screen (perform cleaning on the LVDS cable terminals)
- Dark screen (Add a 1M SMD resistor at position C1 on the Inverter Panel)
- Screen off (change electrolytic capacitors of the Inverter plates and check the two integrated in the two plates).
26PFL3404
- Remote does not work (Check solder on FB02 / IR panel and FB205 / SSB panel)
- Interference when on HDMI (check welds on R1501, R4404, RP4404 and RP4406)
- Missing a color in CVI or altered colors (cold welding in U4201, C1206, R1203)
- Display partially illuminated or off (check T803, Q801 and Q802)
- Inverted or altered colors (Check for possible cold welding on IC U4201 on the SSB Panel. Also check for overflow)
-
Dimly lit screen with no characters (Problem in the inverting sector of
the IPB source, check for possible leakage in transformer T803, Q801
and Q802.)
- Sound and image interference (Check for possible cold soldering or excess flow in resistor R4203 on the SSB panel.)
-
Stand-by led off (Check for possible cold soldering on the Q0201 or
Q0202 transistors on the IR Panel. Also check for excess flow, perform
cleaning near the item.)
-
Lines on the screen in the horizontal and vertical direction (Check
possible connection of the FFC cable. Remove the cable, clean if
necessary and reconnect. Note: The cable locking system is not by
displacement but by "flap" lift the locks by 90 degrees to open.)
- Freezing image (Check for possible cold solder on the CN7503 connector on the SSB panel.)
-
Does not accept the remote (Check possible cold solder on inductor FB02
on the IR Panel. Also check for possibility of excess flow, perform
cleaning near the item. Check possible cold solder on inductor FB205,
U0201.)
-
Does not work (Check for possible cold soldering on IC U4401 on SSB
Panel or on resistor R4403. Also check for excess flow, perform cleaning
near the item.)
-
No sound on HDMI (HDMI Lateral: Check for possible cold solder on
connector 1601 on the SSB Panel. Check possible cold solder on IC U4201
on the SSB Panel. Also check for possibility of overflow, perform
cleaning next to the item.)
- No sound through the PC-VGA connection (Check possible cold solder on resistor R1401, U1401, U4201 or CN1703 on the SSB panel)
-
No sound even with or without an image on TV or DVD (Check possible
cold solder on coupling capacitor C6110 on SSB Panel. Check possible
cold solder on IC IC904)
- No CVI video (Check possible cold solder on inductor FB1205 on SSB panel)
NO HDMI VIDEO
- Check for possible cold welding on resistor R1501 on the SSB Panel.
- Check for possible cold welding on connector 1501 or 1504 (side) on the SSB Panel.
- Check for possible cold welding on IC U4201 on the SSB Panel.
- Check the possibility of excess flow, perform cleaning close to the items above.
- Check for possible cold welding on CN1601
-
Sound with frying noise (Check for possible cold welding on IC U4201 on
the SSB Panel. Check for possible cold welding on the L903 inductor on
the Source Panel.)
-
Keyboard failing or not working (Check possible cold solder on
connector J1or R6 on the Keyboard panel. Check possible cold solder on
connector CN7301 on the SSB panel. Check possible cold solder on
transistor Q4201 on the IR panel.
- Dark screen (Check for possible cold welding on IC IC903 on the Source Panel).
