Does it make the the samsung jingle when it trys to turn on? if it does you need a power supply if not then most likely it is the main board. I would contact you r local service center for help and if the standby lights in the front blink in a certain pattern write that down it is a error code that the technicain can use to solve the problem.

My tv turns on and off by itself the minute I plug in the cable. .... Samsung E6030 led tv hv blinkin red light ...
The problem may be in any three things.No 1: Internal power supply.No 2: The video section.No 3: IFT (Intermediate Frequency Transformer).
Solve:Check all the section one by one and find out where the fault lies.Then repaier the faulty components.
You need to check for standby 5vdc, it should be there the minute you plug the TV into the outlet. This a must have voltage. Replacement power supply is only $53 here: http://www.shopjimmy.com/catalogsearch/result/?q=Samsung+LN32A330+
Please post back what kind of voltage reading you are getting at the DC output connectors.
Had this same issue on right side of 52" about 1 inch from side but had 3 vertical lines that disappeared after 40 minutes. Have Samsung LNT5265FX/XXA and about 16 months old. LCD Panel itself had to be replaced to fix it, fortunately had extended service plan
Unplug TV, take off the back. One each board there will be capacitors. the tops are flat unless one has blown then it is bubbled up. If you find one that is bad, copy the number and search the internet for a replacement. Unsolder and remove the old one ( there is a line drawn on the negative leg, mark the neg side on the motherboard so you can replace the new one the same way). Now solder the new one back onto the board. This worked for my TV, hope it helps
This is Sony's way of telling you that there is a short in you set.Probably the horizontal deflection circuit.(Horizontal output transistor shorted??). Also any other short.
You need to take it to a techincian and have it checked out. It would be wise to get an estimate!
