    its random now where the parts of the screen are dodgy, it was at first 1/4 of the left side of the screen now its 3x1/4 of the screen all are diff shades of a "white mist" as i can see the display behind if i pop the menu up, ive been quoted that it could be too much voltage going to the tecon board?

Ok t-con board is connected to main board which is giving signal and logic supply.. If the main board failed or giving a over voltage to the t-con it possibly your T-con gone out (new) again.

To isolate the problem try to replace the main board.

If the cost of repair is 50% or more of the price you purchase the TV at, your better off buying a new TV.

Your not alone with this problem.
I had to fix mine. The warranty is less than impressive.
The trouble is going to be the Power Supply/Backlight Inverter board.
This is the picture of yours:

Fixing the board like I did seem to be the only option. If you need info on fixing it, let me know.

White line across screen


If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.

Take it to a repair shop.

LG 32LH30 LCD TV Problem


IMO Seriously for $119 it's not worth it.
However, it does sound like a capacitor problem
If you are "Serious" about fixing I'd find a TV repair Forum.
Else I'd go here and get a new one.

Try changing the input device to something you are sure works. If problem persists, it can be due to dry/leaky capacitors and/or dry solder on PCB. Anyhow, this might then require attention by a qualified service technician.

White flickering line across top of screen


Set the screen format using your TV's menu. Do not set the format of the screen using your provider's receiver. I had this prob with a few channels with a dish provider when I set the format with the remote from the dish provider. I picked up the TV's remote, went into the menu, set the format, problem fixed.

TV TURNS ON,LINES ACROSS SCREEN THEN TURNS OFF BY ITSELF


sounds like a vertical problem, usually you'll see one white line across the screen, but one I worked on would come on and the bottom half of the picture was gone and there were lines across the top of the screen.

If you know how to solder & can find the vertical output chip then you could try resoldering the pins. If this doesn't fix it then it needs new parts.

My CRT TV displays a single horizontal white line across the screen. It will flicker and try to display the picture. If you smack it you'll get a quick picture then back to a line. After about 10-15...


The single line means that the vertical deflection doesn't work. And since it is working when you kick the tv or has warmed it's clearly a bad connection - open the case and reseat the wires going to the tube coil.

White Line Across Television


If it is just a collapsed picture and view as a white horizontal line across your screen. Loose vertical IC connection or is start ailing. Best is to reflux its pin with a new lead or resolder it.

But I don't recommend you do it yourself if you don't have experience doing it.

Nasty voltages may caught you.
