Hi guys,how to fix a Ghost picture on Lg 42lf20fr-afb LCD tv?


Ghost imaging is usually caused by a lose connection on the LCD. You need to remove the front bezel and push on the ribbon cables till you find the defective cable. I put a piece of rubber surgical tube type object and put it on the defective cable and have the bezel hold it in place.. You can replace the LCD screen as well.. It's probably cheaper to replace the TV then the LCD. This worked for me several times. YouTube has videos about it too.

Vizio 50" plasma tv has picture but 1/3 of right side screen is black


there are 3-4 boards at the bottom of the tv. most brands call them z sustain boards you either have a bad one or the ribbon cable needs to be reset. be careful with those ribbon cables as they are fuzzed to the panel and cannot be fixed. the board usually cost 20-30 dollars.Good luck!!!

LG plasma screen tv has vertical lines down middle of the screen (changes colors).


Hello,

All Plasma and LCD TV have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them.

I believe this will help in solving the problem....

I have a black bar in the middle of my LG 50pg20 plasma what could be the problem can I fix this.


it might be one of two things , it is either a buffer board that has gone or the ribbon cable going from the screen to the buffer board. If it is the buffer board it can be fixed by simply replacing the board with a new one, if its the ribbon cable from the screen then it cannot be repaired sorry.

Left half of screen has vertical color bars of different colors


Hi

This will be your screen controller board that has failed also known as the ldv's board, With the back removed from your TV it will sit below your power supply and be connected via a ribbon cable to your Y Sustain board on the left.
Remove it and take the part number of the board then Google or Ebay for a replacement.

Take a look at the below link so you know what you are looking for.
Hope this helps

Plasma tv has sound but no picture


Check all the cable connections at the back, if you are using an external receiver , then check the Video cable, eventually try a replacement one.

Try leaving the TV set unplugged for a couple of hours, this will drain power completely and, if there is no real fault , this can fix the problem.

If that does not fix it, then thereis an internal fault.

Common faults that cause audio but no picture concern, digital board, controller board, sustain boards, Plasma screen ribbon cables, and plasma display.

Call the number listed on the owner manual to get assistance.

If the warraty is expired no longer than three years, ask the price fod r a warranty extension calling same number in the manual.

It sounds like you have a bad connection from either the X sustain or Y sustain boards to the panel itself. After the set warms up, the connection completes and the line goes away. First remember there are DANGEROUS HIGH VOLTAGES IN THE SET AND YOU CAN BE SERIOUSLY HARMED OR KILLED IF YOU TOUCH THE WRONG THING SO BE CAREFUL!. I would get a non conductive probe of plastic or wood and, with the set on and the back off, push on the ribbon cables which connect from the sustain boards to the panel. Once you determine which ribbon cable is the problem, disconnect the power, wait AT LEAST 30 MINUTES FOR THE VOLTAGES TO DRAIN OFF and then carefully resolder the ribbon cable connections at the sustain board in question. If the problem is at the panel end of the cable, I wouldn't recommend you try soldering there as it is very easy to damage the panel connections. You may try simply repositioning the ribbon cable to see if you can find a spot with a better connection. Please be sure to rate this solution. Thanks!
