zdravim
robim vymenu posvitu na led tv LG
je tam driver SSC1S311 je mozna regulacia prudu??
robili ste to niekto ?
vdaka

A nebude to nahodou pohotovostny zdroj?

Netvrdim,ze by sa nedal pouzit na podsvit.Ak ano pozri vyvod 6(OCP) a odtial odpory na gnd.

Je to ta doska?.. tak ten chip nema s tym nic spolocne ,je to zdrol pre LED...

tak ries odpory na q801 v sourci.A IC801 riadi prud cez LED..

Skontroluj aj `C802 a C803.
Zvyknu davat po nose ledkam...
edit: Je to tak :
You can reduce the backlight current in LG TVs with LGP32-14PL1 power supplies (EAX65391401) as follows. The current sensor consists of six resistors R816-R821 connected in parallel - 1 Ohm, 1 Ohm, 1 Ohm, 1 Ohm, 2 Ohm, 8.2 Ohm. The total resistance in this case will be 0.22 Ohm. If you remove one resistor 1 Ohm, the total resistance increases to 0.28 Ohm, the current decreases proportionally from 250 mA to about 190 mA.
