Hi Aaron,
I just want to ask you something before I give the solution, does the unit gone to start-up problem (needs warm-up before it finally turn on, needs to pressed the power button key several times, needs to unplug from the outlet and plug it back in)before, you have said that you've encountered it last few months?

Hi Jay,
Previously it took a few times of pressing the power button before the TV stays on. Now it does not turn on at all using this strategy. The last time I got the tv to stay powered on was after I unplugged it from the electrical receptical for a couple of hours. I am thinking a capacitor is not discharging or something. I hope you have a cheap solution! I have a soldering iron and am pretty handy..
I look forward to your reply.
Aaron
Thanks for the response.
This kind of symptoms is an indication of out-of-regulation condition in the power supply section. This is caused by faulty electrolytic capacitor like what you've suspected.
Leaky electrolytic capacitor has a physical indication of fault like bulged/dome at the top and can be easily identify through visual inspection. Watch this link

If you found them on the power supply section, replaced it with same capacitance and working voltage that is printed on its body itself. Watch this video for more info regarding electrolytic capacitor.

Dried electrolytic capacitor has no physical indication of fault, you must have a capacitor checker/tester to determine its condition and pinpoint the faulty one. If not available, you may replaced all electrolytic capacitor except the largest capacitor. It will not cost you much because this is one of the cheapest part on that board, cost only $0.5 to $4 at the most.
Hi Jay,
I need a bit more info.. Where in relation to the back panel is the power supply section.. Should I assume it is behind the panel with the electrical power cord..or is that too simple??
Please advise.
Thanks,
Aaron
Yes, the power supply section is where the power cord's directly connected. Unplug the unit for 1 hour to drain any voltages from the power supply before you repair it...
