A blinking led does point to a bad power supply board! First, Look for some bad caps (capacitors) on the board. They will look bulged on the top an may be a little leaky (brownish stain).

You should be able to find a service manual @

Buying a power board try or ebay!

Good luck, hope this is helpful!!!

Hi, i have a samsung eu40 eh 5300k tv, the power light flashes 5 times any idea what board might be at fault

At this point it would be a guess as to what board is bad without some voltage readings from the power supply, look at the legend and measure the various PS voltages if you feel comfortable doing that.

Hi Ab7775,

1. Pl check st by 5 or 3.5 volts.

2. If it is ok, check power on 5 or 3.5 volts. Is power on voltage stable ? If this is pulsating with cliking sound, it is the main board. Otherwise it should be the power supply.

3. Please also check all the other voltage for short with ground.

You can also check the power supply board separately. Remove the connector going to main board. Put a 1k res between st by and power on pin. Plug in the ac, if all the voltage appear, your power supply is ok.

I am on line if possible please do this checking and let me know the result.

Good luck.

Samsung 40" model number LN-T4061F Not working ADVICE PLEASE.

Please do not assume that a TV works fully by capacitors. Capacitors are only some parts, which are used to smooth power supply, and to bypass signals. There are so many reasons for this fault you reported here. A damaged Main digital board or its back-light inverter board can cause this porblem. Contact any service technician.

Ur power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like, to buy a whole refurbish power supply board for the replacement.
Hope this helps...
