PHILIPS	32PFL3403	Dead	Resistor 1r, position on the power supply board, r-929, replace it, it's ok.		Cláudio Ribeiro, TECNOSAT ELETRÔNICA E INFORMÁTICA, Jataí-Go, This email address is being protected from spambots. You need JavaScript enabled to view it.
PHILIPS	21PT6433/78	When turned on, it displays a reddish image and turns off	When resoldering the kinescope board components, the TV worked for a while and then showed the same defect again.	Changing the red output transistors on the kinescope board 7308 bf422, 7313 bf422 and 7314 bf423, perhaps only one of them was defective, but as I tested and they showed no difference between them and no leaks, I decided to replace them all straight away.

PHILIPS	HTS3011/55	Does not turn on inoperative, does not have normal power supply voltages.	5bk power capacitor c933 without capacitance	Replace with a new 220μF x 16v capacitor	celinvds
PHILIPS	20PT3331 MARCIORV	I'm sound, audio	Electrolytic capacitor 470 / 16v position 2444 near the frey back
PHILIPS	29SX8879 G8	Inoperative (protection circuit acting) tick...tick...tick...	When opened, the l5945 ferrite was found fallen, probably the cause of the burning of d6904 (by228) which was shorted. When it was replaced, the TV turned on but l5980 started to smoke and it was found that the reason was that q7980 (bd440) was also shorted. After being replaced, the TV showed excess width because tsound was no 12v in its collector. Even though the L5980 was shorted for a short time, it is damaged and is the cause of the problem. As it is an offline TV, I managed to replace the L5980 with another one taken from a Philips GL1340 (S516) just by adapting a bridge between two terminals. Note: during the tests q7981 (bc547) also shorted out. Searching the internet I found the following tip on how to recover l580... good morning friend!!! sound is the solution to your problem: the width defect is caused by the burnout of the 5980 coil. Unwind and wind it with 31awg wire measuring approximately 14.30 meters. Once this is done, the voltages (12v) appear and the trimpt adjustments start working again, ok!!b		littlecarlos
