Color lines...circuit board issue??

It sounds like a power surge has damaged the color controller and scan line section of the circuit board. The cost to repair is more then the replacement cost. Next time use a UPS for protection (battery back up for computer and electronics). Regards DaytonComputerDoctor@hotmail.com

usually electrolytic capacitors cause some mulfunctions

Let me start at the beginning---Likely a bad main board in your case but nothing is sure in this type of set.

Main board controls all information to the front screen and communicates to various boards---There really is almost never a simple "that part is bad solution" as any board, the power supply, the main, etc can cause issues.

It can even be a issue with the front screen unit--called a display panel.

You might consider doing some research on the set by Google of the model number with "parts" to get an idea what is available and what potential parts cost might be.

If a main board is bad it will average from one to two hundred just for the part----if issue is the panel you are done--part if even available is more than set cost when new.

Let me know if you have questions.

Likely it is the "main" board that processes all signal although unlikely it could also be an issue with the power supply board.

If you GOOGLE the model number with "circuit boards" and or parts you will get an idea of what the parts cost may be but labor is another issue.

Hello When you get horizontal line, especially colored, it typically means there is a problem internally: either with the LCD inverter (backlight), LCD Circuit board (interprets incoming signal) or the Display panel itself. Sometimes shaking it around can clear up the issue slightly but for the most part it's time to get a new screen. If you have pictures I can verify this is the issue. Any other questions, feel free to ask.

The tv have a problems known as a convergence problems,it dead.Tv have colors lines R,G,B mis alignments,have colors shadow pictures or 3D pictures look alike?The tv convergence board is dead.The tv convergence board must have replace the 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence picture problems.The shop,will cost u like $300-350 for parts and labors.

The problem is in the monitor screen, there is a large circuit board connected behind the main display screen. The video signal is feed to the main board and generates the proper color balance, the second problem is the lamp behind the display is flickering and breaking down. To repair this will not be cost effective, cheaper to replace the monitor. But I would suggest hooking a spare monitor to the computer to make sure there are no additional issues.

That happened to my new plasma TV 30 days after i bought it and the TV repair guy came an fixed it and i saw what he did and he told me that there are 3 circuit boards in back of TV and each one controls their areas, center circuit board was controlling the center screen of my TV which was where the lines were so he replaced it and the lines were gone. this board are usually on the bottom part of the TV and they look alike but they are not due to the connection location., i hoe this help

Hi


Thanks for using FixYa. It seems that you might have a backlight and/or an inverter board issue with this TV set. To start with check the screws on the inverter boards as if they are loose can cause this issue. To access the inverter board you’ll have to pull the back of the unit and check the right side, also check for cold solder joints. It could also be due to the inverter circuits for the backlights. The inverter is the power supply source for the backlights. All this is only recommended if you have some kind of expertise for checking the internal circuitry of the TV as these units have high voltages running even when the set is switched off. The cost to change the inverter board including labor would be around $250, if you get this done by a professional. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

umm trying using it more, i had the same exact problem and we started using it more and more it has recently gone away.Check the wires as well (plug them out and back in)
