Just wanted to confirm the solution (or atleast solution to MY problem).
Thank You to those who posted the solution to this problem.
I have a Samsung 52" HD LCD TV. I bought it 1 1/2 yrs ago and recently had been experiencing this problem of continual clicking and no video upon power up.
It would take approximately 3 - 5 minutes before eventually turning on. I noticed that prior to turning on, the clicking would get faster and the blue light at the base of stand would begin to get brighter.
So, based on the suggestions here, I opened up the back of the TV and located the Power Supply. I visually inspected the capacitors and in fact, found 2 of them that had a subtle but obvious bubble or protrusion on the top -vs- flat tops, like the majority of the caps.
These caps were 2200microfared, 10V rating. I went to my local Radio Shack and bought a higher rated version of the 2200 microfared caps (35V). I Replaced the old caps with these new ones and it solved my problem. :)
There were a couple of caveats though:
1) the higher rated caps were physically larger & had axial leads vs radial leads.
2) The leads of the larger caps were just thick enough to prevent them from being inserted in the board.
3) Rather then make the holes of the board bigger and risk destroying the solder pad, I used appropriate sized leads from some resistors that I had as extensions and soldered the new capactiors to the extensions. Of course you need to be aware of polarity and assure that the leads will not come in contact with each other or anything else on the board.
4) Capacitor Radio Shack p/n: 272-1020. Total cost of both was less then $10.
Hope this is helpful. I did take some pics of the capacitor location and board location. If anyone would be interested in the pics, you can email me @" [email protected]
