    this has happened to me ever since the blackouts last week in melbourne

  • Anonymous Feb 22, 2009

    2 days old and won't turn on from standby either manually which they told me to do or with remote. Told by Samsung to unplug for 45 mins. & let it reset. Nothing. Told by service repair they gave me, that's what he would do, so it is more to it. Personally he said to take it back to the store, which I am.

SOURCE: 46 inch Samsung TV that just clicks but wont turn on

I just fixed this very same problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

SOURCE: rca 46 inch lcd tv, no sound

Go into the menu and change the HDMI Audio settings - the manual will give you a breakdown on this. HDMI is a little glitchy - if you were using red/gree/blue cables before switching to HDMI, you might want to consider going back to them - just an opinion.

SOURCE: samsung tv model no LE40R74BDXIXEU TV IS USUALLY

First the main bd controls the "Turn on" sequences". When you press the Power on button the Main bd sends a "Turn on" signal to the Power supply. The clicking you hear is the Power on relay ativating. If the tv does not turn on and the relay keeps clicking then you might have a bad Main bd or there is s shorted board somewhere else in the set. The Power supply can also be bad. Have a trained Samsung tech troubleshoot the set.

SOURCE: scratched sharp 46 inch lcd screen can it be replaced

The lcd screen is the most expensive component of the lcd screen/tv/monitor.

It makes no sense to try and replace it as first of all you won`t be able to find the part number required to do that job (e.g. the screens are internally made by sharp // special orders are placed to companies that only start the process for orders greater than tens of thousands of items) and secondly after a lcd panel has been replaced / installed you need to configure the colors, luminosity, contrast, balance etc through a data cable.

I am really sorry for your sharp lcd screen.

Thats Samsung for you. They are designed to last just right outside the warranty then fail. Typically the LCD panels are bad, and they are the most expensive part on that Korean unit.
