Question about Toshiba TP43H60 43" Television

1 Answer

Limited blue My TV was working fine and all of a sudden most of the blue's seemed to dissapear and I was left with a screen of pinkish-reds and shades of green. Not all of the blue left however, for instance when I change the volume the back-color of the volume "bar" is still blue. Also, all the menu blue's are still present, just not those on TV shows. I also tested the screen by showing a DVD and by trying my sons video system, all show the same color "issues". Any help would be greatly appreciated. Thanks

Could my picture tube be bad when the words on my screen are doubled with a shade of red? If so how much does it cost to fix?

If it's a projection TV, the problem could just be your Convergence. In the menu, there should be a place where you can fine tune the Red Green and Blue guns.

You have a completely different problem. The screen voltage for the blue picture tube is slightly too high on your set. This will put fine lines in the background of the picture, called retrace lines. This is very common and easy to correct. Remove the front speaker cover and the access panel behind it. Look inside and you will see a black box with six controls, each control having a little white glue on it. This is the Focus/Screen block. Three controls are labeled Focus and three are labeled Screen. The screen control in the center is for green but I am not sure if the screen control on the left or right is for blue for your model. With the TV on, set it to VIDEO 1 but do not connect anything to the VIDEO 1 jacks. This will produce a pure dark picture, showing any faint lines in the background. Choose one of the screen controls and increase (turn clockwise) it slightly. If the blue lines do not get brighter it means you are turning the red screen control, so put it back where it was and choose the other screen control. When you find the blue screen control, decrease (turn counter-clockwise) it until just when the blue lines are gone. If you want you can check that the red and green screen controls are set to just below the point where their faint lines are visible. When done, replace the panels and your picture will be back to perfect.

MikeNJ1964 was exactly right! I have a Sony KP-65WV600 that had horizontal green lines that showed when the picture was darker. I had to remove 3 screws on the right and left side of the tv holding in the speakers...carefully pop out the middle panel from the clips holding it in....remove 4 screws from the cardboard in the middle and remove the cardboard. I then saw the six screws. The adjustment screws were the three below. I turned the middle screw until the lines dissapeared. I tried the left screw and blue lines appeared which I then adjusted away.
THANKS a bunch. SAVED me money!!!

Screen is all Shades of Red....

You need to remove the front tv panel, search for the screws right behind the screen and speaker area on the sides of tv. Should be four of them, carefully remove the lower have/quarter and you will find a control box, 6 knobs. Try adjusting them to clear the problem, each color has its own knob, be sure to mark their original position befor adjusting. When you find the red adjustment knob, you should be able to turn it down enough so that it doesnt overpower the rest of the colors. Good luck.

Only get red screen


First of all Check Flash focus is working or not?(Flash focus should finish 1 full cycle)
If Flash focus not working you will have a error code in your screen.
If any error message or wont compelte full cycle you have problem with convergence amplifier IC
It could be one of your IC bad along with Couple of small Value resistor.

Dont Forget to Rate!!

Good Luck

Pinkish red screen

Your set doesnt have a color wheel you have 3 CRTs instead. Try turning down the red drive on the red crt circuit board that should help if not check the resistor that is connected to the red drive switch Vasriable resistor(switch) that is probably open if not the crt is probably at fault. If you need more info let me know.

Mitsubishi ws-65809

loose connection.
check for any over heated areas and resolder them specially the convergence IC.This resistor is located in the back edge of the chassis in the board in the right side and it might be hidden by a plastic casing that covers the high voltage transformer.If you are not too familiar with tv service you should seek the help of a servicer.Let Us know how it goes or if you need more information.
