SOURCE: TV PROBLEM
After replacing the shorted Line driver Transistor, carefully removing and replacing the same CRT base circuit, resulted with the problem going away. I cannot say what really was the cause, but I suspect that there could have been some form of acing on the neck of the tube.
SOURCE: TV Will not fire up.
try this,hang the collector pin of the HOT then try to switch on check the voltage its 115v dc,and check also the oscillation drive at the base of HOT take your VOM at 10v ac,ther must be a flactuate at the pointer.if the two procedure are good.plyback is deffective.but if u dont have any measured voltage at the collector of HOT ur problem is in the power supply. mc44608 is use at all old model philips tv.email me for wat happend
SOURCE: dead set, HOT transistor keeps shorting
It's the copper coiled magnet on the neck of the crt closest to the front of the tube.
SOURCE: Tv not switching on Sansui SV2918
all the transistors ,& capacitors i.e 47mfd 63v or100mfd 63v must be changed before u on the tv. if 300v is not coming to middle pin of d2449 then 4.7ohm resistor(fusible) may be gone
