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.

SOURCE: The picture on my JVC TV is too dark

On the inside of the TV, on the flyback transformer there should be two controls. Turn the one that says "screen" very slowly clockwise while looking at the pix. The pix should get brighter as you turn it up- if you go to far you will see lines in the pix or the TV may shutdown.

SOURCE: LG Projection TV has dark picture

To do this, press the ENTER button on the TV and the MUTE button on the remote at the same time. After 5 seconds the screen should come up and it will read "Lamp use time...Total lamp use time ....lamp reset" Press the center button on your remote (the circle button right in the middle of the four directional buttons) and you will be reset to -0- again. Your orange light should now be off.

When I select a source/scart on my tcl tv, it outomatically moves to other scarts. What do I do?


Try a reset to this TV first. A hard reset.
There are two types of reset to TVs. The first is simple to do; a Hard Reset; and the other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Unplug the tv and hold the on/off switch on the tv (not remote) for 30 seconds. This should clear any power left in your electronic boards. Then plug it back in and try again.

TCl Remote C198A will not work. I've tried new batteries. "Electric eye" does not light up.


Most shops have a remote tester----have it tested (usually free).

Also , most digital camera's in a very dark room will react on the display screen with a flash when the remote is pointed at them and buttons pressed---home check.

If remote is not sending it can usually be fixed---IF remote tests out as good the REMOTE receiver in the unit is bad.

My Vizio LCD TV screen fades to dark. Sound stays on.


I w having this same issue when watching a Blu-Ray disc. I found it to be dependent upon what picture mode the TV was set to. By this I mean certain picture modes would cause the TV to dim during dark scenes of a movie. Changing the picture mode helped a lot.
