Vibrating lines across top 1/3rd of tv when turned on
When I turn my tv on there are vibrating lines across the top 1/3rd of the tv. After it warms up in time they seem to go away. One technician said it was the video display board, which he said is about $280. He just looked at the picture and did not open up the tv. What would you recomend to do. The set is just 4 yrs old. I am pretty handy and if told what and where parts need to be replaced, I am confident I could do it. Please let me know your thoughts and where I could get the correct parts to fix my tv .

Re: vibrating lines across top 1/3rd of tv when turned on
Your problem is the hyper board, or whats also called the scan board, not the video board. This board is right behind the input board in the back of the TV set. This is a little tricky taking this board out. There are a few tabs that hold the shielding for the onto the printed circuit board, and if your not careful, you can seriously damage the main board. If you get this hyper board out of the set, go to ptscorp.com, call them and give them the number on the shield and they will tell you if they can overhaul this board. Most of these they can and the cost is about 135 to 150 bucks. A new board, if you can find one, cost about 350 bucks or so. Just be very carefulun-soldering the metal tabs at the bottom of the circuit board directly underneath the hyper board. The board itself simply plugs into the main board, but like I said before, it is held into the main board by metal tabs underneath it. Good Luck

The set uses a Hyper board inside that processes all signals, it is well known for this issue, board no longer available=reason is quite simple : about a dozen tiny surface mounted filter caps on that board with age dry out, at first it will work after warms up as poor caps regain some capacitance and seem to be ok.
Buy a new set, you can send that board out and have it repaired/rebuilt but the last one I saw which was under extended warranty cost about 200 just for the board rebuild.
In the last 4 years Here on Fixya I have encountered only 2 people who were able with instructions had the skill to remove the board and replace those caps, both were top notch computer repair techs.
This fault is calle technically as 'retrace lines'. It is with an adjustment fault. Visit this site to get more details and repair help to this fault. Detailed description are given there. "Electro-help" is the site name. Search for it either by Yahoo or google. It is an electronic entertainement equipments service help site.
I had a problem with the TV going on and off several times before "warming up" and then having pink dots. I would have to reboot to get rid of the dots. I called 1-800-SAMSUNG and reported that I had problems with the capacitors. That is what was causing the problems - cheap capacitors and Samsung is aware that this has caused many TV's to malfunction. My set was not under warranty but Samsung sent a technician across two state lines to fix my TV. As long as the problem is the capacitors Samsung will cover this service call 100%. My TV is fine now. BTW - capacitors which are sold in Radio Shack are not expensive. Why Samsung chose to put the cheapest Korean capacitors in their expensive TVs is a mystery. So if your TV need warming up and has pink dots on the screen - call 1-800 -SAMSUNG and tell them your capacitors are malfunctioning.
This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.
