Hi


Thanks for using FixYa. A plasma TV is a very hard working device. It is working harder than any TV that has been built before, and as a result it produces a lot of heat. 75% of technical problems in plasma TV's are caused by overheating problems. X, Y sustain, buffer boards controls picture, fires the gas, and many others functions. When either of these boards goes bad common problems include negative image, no image, vertical or horizontal stripes on picture, turns on and than turns off, and many more. You’ll need to open the back off the TV and check for any swollen/bulged/leaky capacitors on these boards and replace whichever has gone bad. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when switched off.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks
Rylee

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

Intermittently, picture seems to break up into


replace the cable from the source. if the images tiles up it could be the cable and I suggest doing this first: replace the cables, they are the lowest cost to check, and in some cases the cable company will replace the length of cable from the TV to the wall for free (or part of your monthly payment). You could always make your own the stuff for that can be found on sites like www.compressionconnector.com of course you could always buy the cable if needed. I am assuming this is occuring during normal TV viewing. if it occurs while watching DVDs or from other sources you likely have a problem with your TV and may need to get it repaired.

Sony KV-32S66 Picture Rolling Up/Black Horizontal Lines


the problem there is a loose connection on the board,you said that you smacked the right side of the tv and it goes normal.there are parts that should be resolder on the board in order to back into normal operation.

Horizontal blue line


The intermittent horizontal line is cause by a loose solder connection in the vertical amplifier IC.
The IC is mounted on a heatsink nearby or around the flyback transformer.
The way to fix this failure is to add fresh solder where you see some brown spots on the circuitry that were cause by components getting hot.
Good Luck.

How to fix horisontal lines on display ( see the picture)? They stronger when system is restarted and then fading but never disappearing. They always stay the same.


horizontal lines can be caused by either a faulty grapchics card or a faulty monitor. try adjusting the screen refresh rate. if you are using a windows xp system goto

start>control panel>display>settings>advanced>monitor

then adjust the screen refresh rate and see if the horizontal lines disappear. if not, then you probably have a faulty graphics card or monitor.

Blue streaks across picture


Can you describe in a little more detail what the symptoms are? Are the streaks thin lines or are they large thick swashes of Blue? Is yur video still visible? Sounds like it may be the blue convergence amps or the resistor tied into the amps. is there anyway you can post a picture of your screen distortion?

Kf-42610 blue hue and blue dots on screen


Hi Guys

The Blue dots or discolouration you are seeing is due too the Blue LCD screen having cracked from excessive heat. This normally happens when you have a power failure while the Television was on. This obviously because the Blue LCD sits next to the lamp - the main cause of heat. The correct part number on the 60" is A-1086-952-A. It is very, very ,expensive.

Sorry to have been the bearer of bad news. Good luck : )
