This sounds like it will be a power supply problem or a control problem. Both of them will need a PCB replacement. You will need to take it to a repair shop.

Samsung Smart TV lights up but when i connect mainboard it goes into standby and starts clicking and standby light starts blinking in 2s and when i checked voltage its like its switching on and off.?


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

When switched on at the mains the standby button just clicks on and off constantly,what should i do?


Hi Paul

This is a very common problem with samsungs and is down to capacitors in your power supply that fail. These guys sell the kit that you need to have it up and running again in no time, they provide full instructions with the replacement parts and also provide phone support if you get stuck.

Samsung 55" flat panel lcd tv is not coming on the standby button light stayes on but no picture coming on it doesn't come on with the switch only by plugin it to the outlet.


Does the backlight come on? or even flash on and off when the TV is switched on? I presume the standby light is showing 'blue' then. Do you have any sound? Also, when the TV remote is pressed, does the standby light flicker?

Samsung 40" tv not coming on


I would check out the power supply module for bad caps with bulging tops. Check DC voltages at the output connectors, you should have 5, 12, 24V.
