Flickering of screen (comes and goes) and weird DVD/reception problems
Okay I bought this tv used, and everyhting was fine until I started getting this weird black flickering lines on the screen. The picture is still fine and clear. The flickering comes and goes. Sometimes it's there and then won't come back for weeks, very strange. It might be a connection problem inside, here's my next issue.
I had a dvd player plugged in the a/v cables, it worked fine and then all of sudden i got sound and no picture, so i bought a dvd player and it worked fine as well, then the same thing happened. I tested the new one on my friends tv and it works fine. i don't get it?
lastly, i think my coax cable things are loose. sometimes the reception goes blurry/distorted and i need to jiggle the coaxial cable thing. how do i tighten the loose connection?
I'm sure this all connected, but i don't want to open this thing up and break it. so, i need help figuring out why my tv flickers black lines at times, dvd players that work and then don't, and how to tighten the loose coax/coaxial cable connection?

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
on the back of the LCD is a cable that goes from there to the Motherboard. Try reseating that cable on both ends. If that doesn't fix it then it has to be a problem with either the screen or the cable behind the screen.
I'VE SEEN QUIT A FEW SAMSUNGS DO THIS AND THE DIGITAL BOARD IS THE PROBLEM YOUR MODEL NUMBER DOES NOT HAVE A DASH HLR4667W AND YOU NEED YOUR VERSION NUMBER AND MAYBE THE BEST THING IS GET THE PART NUMBER OFF THE BOARD.
Yep, 95% chance it is the power inverter problem.
If you don't remember the screen having a pink tint or flickering for a
while or being dark at the middle top or bottom before it went, then
your bulbs should be okay.
It will need at least all the capacitors replaced.
I fix many of these types on ebay.
If your DVD player is separate from your tv, you might have a loose cable plug or connection.
Depending on the type of flicker you have, a vertical circuit loose connection would cause this. If you could connect it to a cable or antenna it might tell you where the problem is located. A faulty circuit in the DVD might cause this too.
