Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Dark line down the middle of my flat screen tv


Most LCD and PLASMA sets use two boards (some combine them into one board) that drive the Display Panel (the entire front screen unit) so I would suspect one of yours is bad.

The other unpleasant possible cause is where the left board is connected to the Display Panel (entire front screen unit) you have a problem inside that Display Panel and that is fatal as there is no way to get INSIDE the panel---it can cause both lines and a dark picture on one side of the screen.

Our picture seems very dark, We got a new lamp installed about 8 months ago and have played with the colors etc but after awhile the picture just goes darker. any sugestions?


There should be a setting for the dynamic contrast ratio(or backlite setting on some tvs). Turning the dynamic contrast ratio off should make the screen brighter. This is usually called the DCR setting, turn it to off.

When the screen has a light picture you see pink color bloches all over the screen, when the picture is darker it's not that bad. It all started a few months ago with different colored spots on the screen.


Howdy,
The problem is with the EEPROM in the TV that needs to be reprogrammed. But you need to have the proper Correction Tool (LSUQ0100).
I don't think it's available to the public. Call a Service Company, but make sure they have the “Correction Tool”.


Thanks for using FIXYA, big IRISH.

Picture keeps getting darker


I would need more information as to how fast the picture is getting darker. If it is happens over a matter of hours as you watch it the tv may have a lamp driver issue and requires service. If it has been getting darker over a period of months, you may need a new lamp.
