Question about Samsung LE40R73BD 40 in. HD-Ready LCD Television

1 Answer

LE40556P lcd samsung. Screen will not switch on.

I have a 40" lcd samsung le40a556p and it wont switch on.
I have asked currys but it is 6 months out of warranty and they are not interested.
The red LED in the lower right corner switches on and flashes for a few seconds then the tv makes a really quiet buzzing like noise like it tries to switch the the screen on.
Then it just carries on flashing and tries switching on.
The screen does not come at all.
I have opened the tv and can not see any obvious burn/deterioration of components on the power board. can some help me please?

Usually you can see the tops of one or more capacitors bulged up when the power supply board has failed. VERY common on Samsungs.

Hi liam, this is a common problem and quite easy to fix.
Unfortunately Samsung decided to use inferior generic power boards with their sets. They pretty much use the same power supply for the 32, 37 and 40 inch TV's. This is a great idea for production, unfortunately the power supply fails on the 40 and 42 inch models because of load. I find these power boards pretty cheap on Ebay and replacing them is a breeze. Just keep an eye out for the refurbished boards, since these have been beefed up a bit to compensate for the extra power drain.
My how-to is located here for LCD TV repair:

TV won't switch on


1. Your Tv is in need of service.
It sounds like the tube that give light to the screen for visual is defective and needs replacement.
2. The power supply circuit needs repair. Possibly a capacitor or diode has failed in the start up circuit

more likely to be bad LCD panel (very expensive), but you can try replacing the LCD controller first (around $80~100).

Samsung 40 no picture


If it is only 6 months old you probably still have a warranty. This is definitely a hardware issue, and unless you are comfortable taking your new TV apart, I would contact Samsung for repair.
