Any advice on what board I should replace if the left half of the screen is no good, just showing white and black vertical bars? Right half is fine. Is the panel kaput?

Half screen , left normal but only half usable. right was black now blue and white, Dell inspirson 1501.granddaughters so would love to fix


Reseat the video cable connection under the keyboard. If no change, press the Fn Key while Pressing power button, this will start a PSA diagnostics, there will be 2 sets of color bars appear and a Yes or No at the end of 2nd color bar, press N to start the LCD diagnostic. If the LCD is still 1/2 and 1/2 in the LCD diagnostic, you need an LCD. If the issue doesn't appear in the diagnostic, then replace the motherboard.

Black vertical bar about 4 and a half inches wide down center of screen


hi...
It sounds like an Intergrated Circuit (IC) has fried.
Your best bet in this situation is to contact ur tv service operator and let them recommend an authorized service center in your area....

Panasonic SC-PT460 - Little black box covers half of screen


Can you describe the 'box'? Is it the top half, bottom half, a little of either? What kind of TV do you have?

I suspect you might be noticing the aspect ratio of the various source programs being presented differently on a wide screen than you are used to. DVD programs come in a variety of aspect ratios. Normal TV is 4x3, that is, 4 units wide versus 3 units tall. Wide screens are more like 16x9, so a 4x3 image presented properly on a wide sceen would have black vertical bars on both sides. That is normal.

Some people are offended by the black bars and TV's are unfortunately designed to allow gross modification of the image to fill the space. That is akin to taking a photo of yourself and stretching it to fit an improper frame. That probably wouldn't be very flattering to you and certainly wouldn't be accurate. Which is more important - the picture or the frame?

Intermittant vertical black bars on 42HP84


there is a good chance that I can solve your problem, although for me and others this problem usually shows itself as black bars that go from top to bottom, not just half way.  go to the following link and read the entire thread, it is very good info.  I have done this and it worked perfectly on a gateway plasma, but it also works on numerous others.  there is a guy on ebay that sells a fix for $80, and it appears to be exactly what i did.

I have a philips 50pf7321d plasma tv and the screen suddenly split, half picture on each side of screen, and black bar inthe middle.


Black bar caused by a short IC on the ribbon of the plasma panel. Unfortunately it requires a new plasma panel. Cost of a new unit.

Black Bar on screen


You can try to check the connector on the address board on that area, but I'm 99% sure the plasma panel is defective.

Screen split with black bar through center, top of picture shows in bottom


It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
