We have a Samsung LCD (model #LN46A650A1FXZA). Recently, When turned on, it attempts to engage, but instead, seems to turn itself off and try to restart again. So we are just getting the cute musical tones over and over again, as it tries to turn on. We diconnected it from the surge protector-but it did not make any difference.
Optional Information: Make: SamsungModel: LN46A650A1FXZA Already Tried: Removing the surge protector
Hello Welcome
Poor start up problems with these sets and many other models with Samsung are bad electrolytic capacitors on the powerboard
The picture shows a typical capacitor thats failing ie the bulging heads
They can also leak electrolyte or dry-out, the majority of the time though for this condition on samsung models is this bulging or venting of the capacitor due to overstress on its dielectric inside
The solution is to change these capacitors however an ability to solder and desolder is required and a quality soldering station or iron, cost would be under $30
Please let me know if you can do this and I will provide more info
Alternatively the powerboard could be replaced complete available at http://www.partstore.com/ or http://www.encompassparts.com/ a very easy job just some screws plugs and sockets this way would be $100-$150
Just let me know and I will locate the board for you
A technician would charge $250 for this repair subject to the set being brought to the repair facility an independant repair shop would be ok as the fault is now well known
If you have questions or indeed need more info please ask
Regards
Anthony
