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 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.

Red light on my Philips tv goes 7 times

It's basically a common problem with all brands of flat panel TVs. Heat is the biggest enemy for circuit boards. And the flat panel TV generates a lot of heat.
The most common part to fail is the power supply board (Backlight Inverter Board) for the screen or the Main Power Supply Board for the TV itself. The flashing 7 times is a code for a technician look at a certain circuit path for the malfunction.
If you have some electronic experience and you want to repair it yourself, you can sometimes find a Service Manual over the internet for less than $20. It will have red light flashing codes, diagrams, schematics, and part number list. Cheaper than buying a new TV. :)
