Samsung tv model LN52a550p3fxza turns on and off repeatedly. Before this happening it would turn on but screen was pinkish. What part do i need to replace so it will turn on?


Before replacing the power board, check the small high voltage transformer and the high voltage circuit. From the 120 volts AC, trace the fuse, then the capacitor on the other side of the transformer for at least 390 volts DC. The input (control) board has a chip that checks all the circuits including this voltage. The capacitor is 100 uf rated at 450 volts. If the high voltage is not at least 390 volts, then replace this capacitor with a larger one 350 uf rated at lest 400 volts. And see what happens. Good luck.

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.
