Question about Toshiba 50H82 50" Rear Projection Television
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 .

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 careful un-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
