This unit is practically brand new, has no dust nor dings nor damage on the unit anywhere, not even a scratch, but I haven't been able to get the unit to power on. Power cord is connected. The switch on the unit sounds like the others when pressed and everything looks and smells good inside and out! There are no cracks on the circuit boards, no broken wiring no broken or missing or out of place connectors. The fuse is also intact and appears good, but I haven't used a meter yet to check for

When switched on, the power light flashes on and off on the front of the TV but no picture. We have the back part of the panel off and there are no puffed capacitors. Everything looks good except some goop around some of the capacitors. Is it normal to have goop that looks like its flowing out of the caps? Is it a glue that helps it seat better? I have access to a multi-meter and have the checked the output of some of the connectors. Anything to suggest?

My samsung 46 inch LCD also has the problem of no picture, but clear sound. I read all the posts about capacitor problems, and have gone so far as to take the back off and the power supply cover to look at the capacitors.

When I first power up the TV, it looks like it is lighting up, but after maybe 1/2 second of buzzing, the dim light goes off completely. Looking at it from the back with the cover off, you can see the

I have a WS-65611 that I have replaced the caps on the DM board. Before I did that, the power LED flashed non stop, Now it does the normal 70 seconds but when I attempt to turn it on, it shuts right back off. After attempting a power up I checked the error code I got a short protect error. I then removed the DM again and verified the caps were not shorted to the shield and checked the pico fuse and found everything to be good. Any ideas of where I should start looking??
