Multiple colored lines on my tv, then about 2 minutes it shows the picture. I replaced the t-con board, now what?

Unfortunately, lines in the screen is usually caused by a bad LCD panel. You eliminated the T-Con as the problem after replacing it. A replacement LCD panel is very expensive. Buying a new TV is cheaper. Sorry.

I'm sorry but nothing can be done to fix the problem because it is defect of lcd panel (screen) that will be replaced but it would cost you approx new tv price so new tv is better choice instead of lcd panel replacement in this tv.
Again, I feel sorry for the bad news.

Black line going down middle of screen and one side of picture darker also picture sometime is distorted on bottom

if the line is pixel thin, it could be a bad lcd panel. if it is a wider bar, it may be in the video circuitry. many of these sony tvs had bad panels, and sony has extended the warranty. call up sony with your model and serial # and date of purchase and try to get them to help you out, that is your best course of action. let me know if you need more troubleshooting assitance.

Olevia tv

If an LCD TV has sound but no picture do the following:

Use the source button to ensure that source is not set to the wrong input.

Try unplugging power cord for ten minutes, to ensure it is not a setting problem.

Check all the video cables at the back of TV.

Check Light /Color settings.

If problem persist and does not depend on external receiver or settings, then it is likely an internal fault.

If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:

The inverter is the high voltage board that provides variable power to the backlight lamp. This is the most common. When inverter is faulty you can get no picture, or a very dim picture that can only be seen by pointing a torch light with a 45 degree angle on the LCD surface from very near distance.
The inverter must be tested by reading voltages with a multimeter.

The LCD ribbon cable/LCD display and connectors.
This is quite uncommon, but happens. If the TV had been hit or moved the LCD cable may have slipped out, or the LCD connector may be damaged.

The LCD controller board.
This is the board that controls the video signal, it is difficult to test, as there is need to read determined values on IC pins. To test this board you need to purchase a service manual and follow the troubleshooting diagrams on service manual.

Input/Output Signal boards.
This are the boards where you connect the video and audio cables, if a signal board is defective, then you may get no picture on particular inputs located on faulty board.

If under warranty contact the manufacturer ringing the number on the user manual.

If you want to repair at your own expenses, just locate any good qualified repairer.

It sounds like part of the video subsystem is overheating.

If you see one horizontal line in the middle of the screen, it is probably the high voltage fly-back transformer.

Do you hear a snapping or popping noise when the picture is lost?

LCD monitors are divided up into smaller strips. Each strip has it's own video driver. That strip has either lost it's power source, or the board is bad. Might just be a loose solder joint, if you are lucky.
