LED TV Repair Tutorial Common Symptoms Solutions How to Repair LED TVs

Hi Tom

Sorry to hear about your Lemon. I learned about Samdung products awhile back.
I refuse to buy any of their products because of their bad attitude.

The Non Innovators who reverse engineer to get ahead in the market & program devices to work super fast on benchmark tests.

A bit like FolksWagon did with falsifying dynamometer results for EPA readings.
I know all businesses can make mistakes and make poor choices. But, we really shouldn't support companies that blatantly falsify to get better market share.

All electronic devices (inc HD TV's) have problems with Electrolytic Capacitors fizzing out. It's a huge problem.
But I'm sure "some" companies buy underrated parts to insure they don't last too many years.
Go with respected companies like Sony, Panasonic, Hitachi etc.
and check the following before buying.
Warranty period
-(Nice if you can get 5yr like my Mitsubishi Electric Fridge)
User interface - The on screen controls. Ease of Use.
Input Ports - USB, HDMI etc
The video codec's that are supported. eg .avi, .MP4 etc
the more the better. (Look how many codec types VLC support)
Plug a HD drive into the USB. What movies can it support?

Cheers

I have a 50" Samsung led. and what mine did was click and click before turning on. the clicking time increased periodically until it just clicked and never turned on. I called Samsung and they said that '08 TV's were made defective and they sent a tech. to replace the power supply module and it's been working great ever since.
