Samsung le32r71b blinking power light

[bill25]

Hi

I have the lcd samsung le32r71b.

The problem start when one of the cables from the motherboard to t-con hit the
casing of the transormer in the first part of the pcu. After that the tv only blinking the power light and not start up. The psu have the volts to the main for 1 second and stops . This happens all the time until i cut the electricity from the tv. Only standby have stable volts 5,9. How understand if the psu is fault or the motherboard?

Is that the picture of your power supply or someone else power supply board?
How about showing the pictures of YOUR boards?

No the picture is from the internet . I found a way to start the pcu without mainboard and all the volts is good 12v , 5,4v ,13v , stb 6,2. Maybe the problem is the mainboard.



This time the pics is mine.

Thanks.
