Samsung LCD TV backlight switched off

When watching, the backlight simply switched off. Sound was still on, and also the LCD was working (just hard to see without backlight). - I switched the TV off and on again, the backlight was working again for 10sec, then it switched off again. - I switched the TV off and on again, the backlight was working again for 3sec, then it switched off again. Now the abcklight remains off. I checked the inside of the TV, but could not find anything which looks broken etc. Will try to attached some pictures here. Does anyone have an advice reg. what exactly is broken? Many thanks in advance!

SOURCE: My Samsung LN-S2651D has sound but no picture

Hello,

Check with Samsung, this model should still be under the 3 year warranty. You are having a problem with the backlight power supply. You can look on the back of the unit for the manuf. date, if its less than 3 years then go to www.samsung.com and process the online service request form.

I hope this helps,if so please rate our solution.

Testimonial: "Your suggestion sounds about right to me, though I'm no expert. I do have experience with bad caps in other equipment and am comfortable around circuit boards and soldering, etc., so I'll have a go at it. Might these be low-esr caps? Once again, thank you."

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Samsung LCD TV backlight switched off


Most likely you will need to get a diagnoses done on the set. It could be a faulty 24vdc circuit (power supply capacitors), defective inverter, or a failing CCFL backlamp.
