The power supply capacitors are getting bad - 1000uf 10V- they need to be changed before they blow completely - dead set.

Samsung LCD 1080 flat screen tv model LNT4661FX/XXA clicks before taking 30 seconds to turn on.


Delay in turning on in flat panel TVs is mostly caused by weak and defective electrolytic capacitors in the power supply board. Most of the times they are easily recognized by their bulged top. Some times one has to hunt for them. If one can do it, it is a simple job. Good luck to you.

Samsung 40" flat screen looses sound


this problem started on my LN-S4051D a couple of years ago. eventually the sound stopped working altogether. I then started using my surround sound speakers for the TV via optical out but soon that stopped working as well. I recently took the TV to a repair shop who said that the main board is bad and needs to be replaced. Labor plus parts was going to cost me $400. I said no thanks and paid for the estimate. Good luck.

Yesterday turned on all I get is a black screen,


Sounds like it may be the backlight inverter. Have you disconnected from the mains when you turned it off? leave it for 24 hrs then re-connect. this should be covered if you have a warranty
