New Samsung LN40A550 LCD TV: picture is not crisp.

Assuming the cable feed is not the problem, what picture settings do you think would improve the definition ? Does this unit have any quirks one has to work around to improve picture quality ?

Can somebody pls. help...our tv Samsung LN40A550 LCD would not turn on...the red light (power) keeps blinking & the blue bar is turned on too as soon as you plug in the tv but the screen won't turn...


This is a very common problem. The power supply board has failed and needs to be replaced. You can call 1-800-samsung to find out if this problem will be covered under a warranty and the nearest service center. I replaced at least 150 power supplies last year.

I bought this on clearance. I hooked it up and


Samsung LN40A550 LCD TV

This is probably the LCD Controller (T-CON) board connections. This is a small board with 2 flat cables connected to it which run to the LCD screen. The connections with the flat ribbons needs to be reseated. The heat makes the connections misaligned. This board is usually covered by a metal shield.
When you reseat the connections, run the set for 15 minutes to see if it works before replacing the back cover. You may have to reseat it again.
Remember, handle electronics boards by the edges, no static electricity, and do not touch the connection contacts.
At worst you would need a new board. (Shopjimmy.com has it for ~$90.00usd)
