| PHILIPS |
20 PT 524 A
|
Power supply tripping, diode d 6550 shorted | Faulty power supply chopper transformer, with the ferrite dislodged | ||
| PHILIPS |
20 PT 424 A
|
Inoperative (does not turn on) | Transistor t 7400 (bf 422) with leakage between base and emitter | ||
| PHILIPS |
20 PT 120 A
|
Without the osd characters | Defective smd transistors 7622 and 7681 | ||
| PHILIPS |
14 PT314A
|
Image split in half, vertical strip on screen | Diode 6401 (1n4148) shorted | ||
| PHILIPS |
14 PT110B
|
Does not turn on, the LED flashes quickly and returns to stand-by mode. | Horizontal output transformer (fly back) faulty | ||
| PHILIPS |
14 PT110A
|
Inoperative power supply | Capacitor c 2540 (100 uf x 25v) with loss of capacitance | ||
| PHILIPS |
14 PT 110
|

| PHILIPS |
29PT5642
|
Image shifted to the right with a dark bar on the left side | Check possible change in capacitor 2486 (27pf) | Replace the value of the 3430 resistor from 120k to 220k | |
| PHILIPS |

|
Gray screen (no video) | - check the fit of the trident panel to the monopanel. | ||
| PHILIPS |

|
Momentary loss of tune when changing channels. | - change the "video blanking" value from 000 to 007 at address (dec) address 0372, this variation from zero to seven provides a change in the time in which the screen remains dark from 1.3 to 1.6 seconds. | ||
| PHILIPS |
29PT8422/78
|
Does not identify stereo. | - the l05 chassis has a routine that only makes the "stereo" signal identical after 90 seconds, if the customer asks about this feature, it can be resolved by executing the following sequence:1) enter service mode;2) enter nvm mode;3 ) change the value present at address add1020(decimal) to 00. | ||
