NTC resistor
NTC ( Negative Temperature Coefficient)
Many power-supply manufacturers use a negative temperature coefficient (NTC) resistor in series with the line. An NTC resistor offers tens of ohms of resistance when cool, dropping to less than one ohm as its temperature increases.
If the power supply is cool when turned on, the NTC provides good inrush-current limiting. Its effect on efficiency is reduced as the power supply warms up. However, this approach is not effective over large temperature extremes.
A power supply used outdoors in the northern winter may never warm up enough for the NTC's resistance to drop. Conversely, a supply in the hot summer sun will be very warm even with the power off, so that the warm NTC resistor will fail to provide adequate inrush-current protection on startup.
An NTC resistor can also be problematic when a user turns the system off and then immediately switches it back on. The capacitor voltage may drop, but the NTC resistor will not cool quickly enough to provide inrush-current protection.

Pozdrav svima!
Meni je potrebna šema za Primu, model je XT-5102 B/G, pa ako neko ima bilo bi super da mi pošalje na zetelica@gmail.com. Hvala puno unapred!
Molio bi shemu za Sony KV-29LS35E, dioda 11 puta blinka pa da probam naći CN 703 nogica 4 na (RGB) odnosno pločici ekrana.
Navodno bi tu trebalo dolaziti 8V. mail: prle76@gmail.com Hvala
kod njega mi je problem sa nekim hladnim lemom, pretpostavljam jer posle 10-20-30 minuta rada - frekvencija programa počinje da se pomera pa mora da se podešava na tjuneru.
Proveri: dali ti ovo nesto odgovara

molim te, ak imaš, da mi pošalješ shemu Quadro CTV 72F12 TXT ...ili ovdje ili na mail...
Evo opisa kvara:
neće da se upali ekran, lampica se pali gasi i cuje se relej kako prekida i zujanje trafića kao da je u preopterecenju. na stampanoj ploćici je bilo malo crno oko IC 604 (5Q1265RF) koji je na hladnjaku i neke prigušnice i kondića 2n2.
