About 2 inches of the top of my screen won't show. Sometimes it will turn into a line that runs through the center horizontally. If I hit it it will go back to normal except still missing the top 2 inches


hit your TV lightly on left side or right side or on top & then observe ..........you will get normal picture or it comes & again it goes....if it is happening like that then following is the situation..........after 4 or 5 yrs in some TVs on main board at some soldering joints crack develops....then due to loose contact picture becomes small in size or disappears ...........when we hit that lightly then those loose contacts joins temporarly & again picture appears for some time............so solution is ......TV main board should be observed carefully & most of the joints should be re-soldered.......only a good service engineer can do that........even after hitting TV lightly if there is no response then main board has to be checked completely........in your case iam sure it is loose connection problem.........joints should be re - soldered ...100% it works again (2inch on top will also gets solved )................this problem cannot be solved by user unless user has idea about components( resisitors, transisitors, diodes,...etc) , have soldering iron , multimeter & other tools....................so contact good TV service engineer

Horizontal line through the middle with sound. If you hit the side of the TV the picture will come back and then go away again.The TV is about 10 years old. Every now and then the picture will flash...


sounds like an intermittent problem. it could be a cold solder and it needs to be resolder it at the VERTICAL IC or transistor section , if your good with tools , you can do it yourself , otherwise take TV to a nearest repair shop, hope this helps , AJ

My vizio 37" plasma tv has a green line running down the right side of the screen


Vizio does not make 37" plasma TV. for the green line problem, does it happen on all inputs or just when you what TV (cable or satellite)? That line should only be present on some channels due to signal processing compatibility. To get rid of it, you can use the horizontal size adjustment and expand the picture side way.

JVC PD-42DX6BJ plasma 42 inch black horizontal lines over the pic


Here's a link to order the original the JVC upper Y-buffer board and lower Y-buffer board for this model from a major parts distributor if needed:


JVC "PD-42DX6" Replacement Part Upper Y - Buffer Board (LJ41-02760A)

JVC "PD-42DX6" Replacement Part Lower Y - Buffer Board (LJ41-02761A)

Based on the symptoms: It is possible that the Y-buffers are faulty, which may require the replacement of the Y-sus board as well. You may want to get a local technician to diagnose the unit and provide a second opinion.

One green vertical line in HDTV Vizio 42


Try changing the H/V position in the TV Set Up menu. You can adjust the horizontal and vertical position of the screen and move it enough that the green line disappears from the screen.

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.
Good Luck

Horizontal Lines


The unit most likely has a short in the horizontal section and would require repair by a service center. Go here to find a JVC repair center in your area http://maps.jvc.com/cAscList/
