Where to buy this power supply unit



The router is able to detect WiFi dongle that is attached to the TV but can't switch on.

Does anyone know where I can buy the psu to replace?

Thanks.

Such item is controlled by manufacturer so can only buy from Samsung.

You have to open up the TV and look for the power supply board. If WiFi is on, this could means only supply to LCD back light is bad. Some part of power supply may be bad.

You may want to refer to the repair thread. It may be expensive to repair due to labour cost unless you can diy.

Try open up the back cover with power unplugged and take some pictures on power supply. It may be just capacitor issues.

if you can remove the PSU board, it should be a very easy repair job...
SMPS repairs are very common...

Such TV parts are controlled by the manufacturer and only their repair man can buy from them.

That is the old way of doing thing and after u changed it will be faulty again so nowadays they change the whole thing. Sometime immediately it blow up again or other components blow up and it keep repeating.

For TV, I repaired mine becos it's on warranty. LCD panel spoilt. So Samsung replaced a panel for me. The invoice amount end up was~$800. This price think u would rather buy a new TV.

For your case, it could be also becos LCD backlight spoilt. My even older TV kena. Turn on see a black screen, but when u look closely, u can see a faint image. Just cannot see clearly becos no backlight
