Question about Samsung LN-T4671F 46 in. LCD Television
Hi, well this usually indicates a Power Supply problem, usually a Capacitor, (Or similarly affected component) which is a high Resistance at first, as the current flow through the capacitor, it breaks down, and temporarily "Heals" then it starts to behave as it should, then when turned OFF the current leaks out, and it returns to it's high resistance state and thus the whole process is to be repeated, this will occur until that or something driving or being driven by, fails completely.
you really must obtain a service manual if you wish to DIY.
I have searched but was unable to find your exact one, however i have included a training manual, right at bottom, this is what is used to train the engineers on these sets and gives valuable insight into how they work and what to do.
It is my professional opinion, though, that everyone should take their units to their manufacturers approved service center, contacting a head office, of your units manufacturer, Samsung, in your case, & getting an approved service center is just SO important, even worth the extra to ship it, you see, at those places, the Engineers, are trained on the equipment you have, they usually have parts on hand, and do the job quicker. Anyway do that and get a "Quote". from them before allowing any work to commence. This way, at least, you'll know weather to repair or replace.

This is actually a fairly common occurrence with these samsung tv's. Most likely you have failing capacitors. If you take the back off the tv and inspect the boards for bulging/leaking capacitors you should find the culprit/s. Replace them if not all that are like them as well. This should fix your problem. If you need to find a local quality repair technician who can do the soldering.
