Re: Samsung LN40B630N1FUZA - Backlight Inop
I am having a similar problem with same model TV. I purchased a power supply board repair kit from shop jimmy everything worked at first but after an hour or two of testing the tv the backlight went out and then came back on but now and it did that a few times. But now I have no backlights working. Image is seen on screen with flashlight and sound is coming through speakers. I have tried checking the resisitors that Glitcher suggested and had the exact same readings as monte1967.
On standby CP816 and CP815 measure 166V.
DP810 and DP804 also measure 166V.
When I turn on the TV CP816 and CP815 Measure 385V.
DP810 measures 385 on the cathode side and 110v on the Anode.
DP804 measures 100v on the cathode and the anode sides.
Does this indicate anything is wrong? I am trying to improve in my skill level from just swapping out a bad board to swapping out a bad component. Thank you for any ideas or information.
