Question about Samsung 46 in. LCD HDTV

Cuts off and on and makes terrible noise

It will often take the tv 15-45 minutes to come on..it sometimes comes on with a faint picture behind a lot of noise and makes a squealing sound but will finally start after some time of cutting off and on...it also seems that one of the HDMI inputs does not work most of the time and we have to switch locations for the input

Yeah, you most likely have the same TV I do. I changed the capacitors and it kind of helped.. I discovered the problem is with humidy and rainy days! Is your TV near a window? I ordered a screen power inverter but just moved the TV upstairs and away from excessive humidy and its been fine ever since. I might still put the inverter in eventually.

SOURCE: Samsung LN-T4661F - When I turn the T.V. on, it

In this case, I believe it is the power supply board; more specifically the capacitors are failing. When you have the clicking problem and the long boot up times this has generally been the issue.

When you have video display problems such as shadows and lines that go away after warming up it is usually the LVDS cable and T CONN board going bad.

I had the shadow and line problem and replaced both the cable and board for $120 and that fixed my problem. Since I had the TV apart, I went ahead and replaced the capacitors so I wouldn't run into that later. You can find the parts numbers for the LNT4661F cable and board below. You can find links to you tube ( Part 1 & 2) to show how to replace the capacitors. Good luck.

TV clicking on and off with colored screens and noises, not power supply capacitors this time.


Sounds like a main board fault. Contact any service technician to confirm. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

My Sharp Room Air conditioner (Mod.AF-S120FX-A) when it's starts


Most likely the terrible noise you hear is the compressor starting... Sometimes it is louder than when its runs continuous. Just make sure if the unit is shut off allow a few minutes for the freon to equalize before restarting the unit. Its possible that the Compressor is going out, But as long as it cools and the noise goes away after a minute or so, i wouldn't worry about it to much.

"Fonzie-ing it" ? It's terrible that I understood what that meant. lol

Sounds like the tuner has a bad solder joint. You may need a Repairman.
