Question about Panasonic PT-47WX51 47" Rear Projection Television

Picture off on screen vertically-Black at top of screen and pic below bottom of screen

The picture is off vertically. There is a black stripe at the top of the screen. The picture runs off bottom of screen so you can't read the taglines at bottom of screen in news reports and such. Is there any way to adjust vertical screen on this model? I know my TV repairman went into service mode to try and fix it at one point, but he couldn't figure it out. Can it be done in repair mode? And if so how do you get in and what do you do? Thanks and hope to hear from someone

Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move tpicture off on screen vertically-Black at top of s - 2c07611.pngdirections your convergence chips are bad and should be replaced. This is a common problem.

Solution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around picture off on screen vertically-Black at top of s - 578ba6c.jpg

Black vertical stripe on screen

hello,if the stripe goes completely thru the screen top to bottom,you most likely have a defective plasma panel. Other instances will require substitution of the drive boards(c boards) and rarely the control board.

TV picture has moved up

your pic. has shiffted vertically. very easy to fix. open the tv set, located the crt tube(end of the screen) there are four wires going down to the board that is compined in one socet. around that socet, you will find small knobs, look for vertical phase and you could adjust that pic. the adjusting should be done while the tv is on and has pic so be careful, you are dealing with a live electricity. good luck

Half screen activated only

When only a half screen is produced, it is usually a upper or lower buffer board, if the top half is blank then it is the upper buffer, and of course if it's the bottom half then it's the bottom buffer board
