Question about Samsung LNT4069F TV
Hi my name is Eric,
I hope I can help you with your issue ,
The TV not starting properly you should hear the tone noise (bleep bleep) not a ticking noise or no sound .
These Samsung LCDs have problems with the power supply capacitors going bad, a servicer will charge between $200 and $450 to repair it replacing either the capacitors or the whole board.
here is a DIY (do it yourself) solution:
It could be just a few bad capacitors on the power supply, if you want to attempt the repair yourself you can do a visual of the power board caps will appear swollen on to.
We do not recommend do it yourself, but depending on your knowledge and technical ability you may be able to.
with the back removed you will usually see two circuit boards the upper one is the power supply, it has a few capacitors on it (cylindrical standing straight up soldered in mark on the sides with the positive/negative sides and MF and Volts values)
Samsung uses mostly 1000Mfd at 16Volts rating capacitors, they cost about $1 each (680mfd will also work fine)
usually I replace about four of them (or all the bulged on top ones) .
The power board and back unscrew with a medium philips screwdriver, if you do not know how to desolder and resolder then do not attempt this as you may damage the TV more than fix it.
best of luck to you
Hope this helps, if it has solved your issue please click accept

I got my samsung TV fixed. First problem was that after 2 years the digi box broke down... ok I used external digibox. Then TV didnt want to start... it started after shutting and powering about 4 times after that it worked fine for 6 months. Then TV shut down permanently and it didnt start at all. I took the motherboard to a guy who changed 4-5 capasitors... they were broken. I went home and it still shut down automatically after a minute. I pressed exit from the remote control about 10 seconds and service menu opened. Then I chose "reset" I think it was option 12 from the list. You go down with the arrows and when your on the right place press right side from the arrows. Then TV shut down... when I restarted the TV it was fine. Hope this helps somebody but the technician said that this is a common problem in samsung.
