My Samsung TV model LN52A550P3FXZA give a discolored screen with a loud pitching noise when I connect anything into it. I did a factory reset and firmware update already. Any suggestions why this is?


Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Model LN52A550P3FXZA. Video and audio cycle on and off every 30 seconds or so. When picture switches off, the screen is filled with multi-color horizontal lines.


It is a common problem for this model, the problem is the main board. There are 2 Tantalum capacitors (C102 & C131) 47MF/10V, 1 Passive Voltage regulator KIA7805AF (IC300), 1 Step-Down Power Conveter IC MP2363DN (IC101) need to be replaced. If you do not have soldering skills, just order a new board.

I have a Samsung LN52A550P3FXZA 52 inch TV. When pressing the power button, the TV clicks for a long period of time but will eventually turn on. Please help with any solutions. Thanks!


You likely have a power supply capacitor(s) that has gone bad. This is an easy fix, and I suggest you search youtube for "samsung capacitor" and you should get some good videos how to repair it if you can solder. If not, any friend who can solder can probably help you repair this with a couple dollars worth of parts form Radio Shack.
