Samsung lcd has no power, the red power light doesn't even come on. Could this be a fuse? Power supply board? If so, where are the fuses located?


Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

Monitor won't stay turned on. You push the on button and it flicks on and then immediately off. Help!


The possible problem of your monitor is may be cold solder, bloated elec. capacitor or defective lcd panel. If you found that bloated capacitor replace it and resolder all pins of inverter area. Defective lcd panel could cause of display flicks then immediately off.

46" samsung flat screen takes 30 to 50 minutes to turn on


Hello,This sounds like a capacitor malfunction. Check the capacitors on your power supply boards (there should be two of them one is the AC input board and the other is the main DC switching powersupply). I have seen this before and every time it has been a series of dried out and bloated capacitors, effecting voltage regulation.Check for bloated capacitors and replace them, then check the voltages at the test points to make sure they are within specifications.You will need a multimeter, and the schematic for this TV set.I hope this helpsThank you,Shuttle83http://www.electron-age-technologies-llc.com

Samsung lnt4042hx/xaa 40in lcd tv wont turn on


I concur with Lightnbaby.... had same problem... my TV LNT4042HX/XAA took 10 min to start sometimes... the capacitors on the power supply board had bubbles on top 4 of them all 10/1000Uf. Samsung wanted to charge $220+ to have a guy come out and fix. J&J parts (samsung vendor) wanted $108 for a new board. I replaced the 4 capacitors for $4.68 and the TV works fine now!!!!!
