Re: Samsung LA26C450 E1D no power led
yes it only has 5ohm, in fact all the power lines are shorted, except for 1 (also 5v) which i guess supplies the 3.3v to toe front buttonsLeave a comment:

Samsung LA26C450 E1D no power led
I have this samsung tv with no power led. Here is a link to the service manual
but it does not have any schematics & my PSU is different
When I disconect the main board I get all good 13v & 5v at cn802 (connecter from psu to mian board) & the back lights come on, as soon as I connect the main board the 5v at cn802 drops to 0.5v, also the pin to the front led only has 0.5 volts (should be 3.3v) all other pins to the front switch panel have 3,3v. without schematics im not really sure where to start...
