TH-42PX75U horizontal lines (flickering black and white)


The controller board for the screen is going bad. check shopjimmy.com for replacement parts. It's not a difficult job to do. Once the back of the TV is removed, you'll see it near the center of the screen.

Horizontal lines shadowed / blured picture after 20-30 minutes


There are some semiconductors or capacitors that are leaky. Might need thorough check up inside the TV.

There's 4 horizontal white tiny lines appear on screen to make the picture become 4 equal parts from top to bottom with many horizontal lines. My TV is Toshiba Lcd(40RV52U)


You have failure/weakening in the vertical section , the retrace lines appear due to the change in the freq.
Check out small value capacitors in this section. confirm by shorting parallel with the right polarity. Unless you are familiar with electronics please do not attempt unless with help. the fault is not very serious and could be attended with low expense.

You may have bad T-CON board, try cooling it with small fan blowing on the vents of the TV.

Flatline!


the vertical drive ic that drives the yoke for vertical sweep has blown.
sometimes it is solder problems like sharp and toshiba had.
the part is 10$ the pc board will label it ,the yoke is the coil setup on the picture tube.if you follow the wiring half goes to the horizontal drive,and the others to the vertical section.the chip drives the coil directly.there are VERY high voltages in there ,even turned off. the pix tube cap on top is 30000v. like a stun gun.the horizontal drive 2000 volts and the main power supply 165 volts dc high current.you need a special setup to discharge the picture tube.
