Hi, My SAMSUNG LE40R88BDX/XEU LCD 40'', isnt working! When you turn the TV on it sounds like someone is constantly turning it on and off with the remote, as its making a constant switching on and off noise, no picture is coming up and the red light keeps flashing. Can you help?

Refer its user manual to get more details. Its specification page will give you all you want to know.

Matthew, I found this link which covers the basic possibilities for connections. It has a video backed up by the text version as well. Hope it helps.

the defective caps in general will be blown upwards there heads will not be flat the value will be indicated on the defective capaciter you must respect polarity .

It sounds like the power supply board has some bad capacitors that need to be replaced. Samsung is covering the cost to repair this problem on some models. You can call 1-800-samsung to find out if your unit is covered.

You will need to have the power supply board replaced. This is a common problem and Samsung has re-designed the new boards so this will not happen again. You can call 1-800-samsung for the nearest authorizd service center.

It will be to expensive to repair. Stop the search.You are looking at over $1000 on the low side.

This seems to be a common problem and is possibly caused by samsung using faulty capacitors in the power supply. It seems to happen to lots of different samsung models. If your TV is out of warranty and you can manage a soldering iron, you can have a go at fixing it yourself (or someone with basic electronics skills) . Check out http://www.earthinfo.org/samsung-tv-makes-a-strange-clicking-sound/ where there is a tutorial on how to do it yourself.

Try a Logitech Harmony universal remote, they can be uploaded with the drivers from the internet and this might do the trick. Otherwise you can contact Samsung and ask for a replacement of the original remote.

if ur surround hasnt got digital in then it wont work also its better to use the red white and yellow wire, i have hdmi and them wires hooked up and i have sound through everythin all i have to do is put it on aux 2, try it out
