46 inch Sony flat panel lcd has vertical red and green lines down right side of screen and you can be watching tv and picture will go right out and leave grayish blank screen until restart. Black horizontal lines appear when turned on

T-con is not the problem. The main board is.

Your LCD panel has failed, it will be cheaper to get a new set. If I have helped you please sign my guest book

I just read some Sony literature about T-Con issues and how to determine if the problem is the T-Con or the LCD panel. One of the examples they gave was exactly as you are describing. Unfortunately according to Sony the panel has failed and the only way to fix the problem would be replacement which is very cost prohibitive. Your other option would be to contact Sony and make them aware of your situation. Try speaking with as many people as possible and write down names. I have heard of times that they replaced the TV for free but to be honest I don't know of anyone who has been that lucky. Their number is 1-239-768-7547 Monday through Friday 9:00am to 8:00pm ET.

More than likely your control board. Available at www.partstore.com Cost could be between $130 and $200. Not that complicated to install if you can use a screwdriver and are careful. Let me know how this works out.

What you're describing is usually the result of an improperly seated connector. With the power disconnected, open the tv and locate any connectors between the LCD screen and the driver circuit board. Unplug them, and reconnect it assuring it's properly and firmly seated. Be careful when handling these cables as they tend to be quite fragile... take your time.

Thats a pixel data problem, there's no data being sent to that row of pixels so they don't change color. This is a pixel address registry (PAR) issue and the PAR circuits need to be serviced its usually due to open or shorted SMT components on the PAR circuits. PAR also sends data, voltage, and control to each pixel, the green line you see are pixels that have voltage but because there's no data sent too them their all green because there's no control. If the pixels have voltage but no data or control they show up as green red, blue, yellow, or whit line vertically down the LCD panel. The vertical-horizontal section of PAR are controlled by 16 to 32 bit micro-controllers which may need replacing. If its under warranty take it back if not have your local repair center fix the tv for you...

hi

I think your TV have a trouble inside lcd panel
the controller board contains driver IC. Deffective driver IC can cause of line display.



Three reasons why one vertical line accross screen can happen in LCD;

1.The missing signal from the controller IC to
LCD driver.
2. LCD driver IC itself defective
3. Dry contact in the tape carrier package.

Use masking or electrical tape to mark it where the line was located. press it if the line back to normal but when release your hand came back i think it was intermittent. Open the LCD panel


Use robber

Place the rubber on the top of TCP

Gently close back the top casing


Good luck...

LCD correct?

There are 2 types of lines they may be showing, both requiring the replacement of the LCD Panel.

1. Delamination Lines- they are usually multiple vertical lines that do NOT flow from the top to bottom of the screen. Looks look water dripped down or something similar

2. Single/Multiple Vertical lines - This is normally 1 or maybe a few solid vertical lines that travel from Top to bottom. I belive in some cases they may only travel to the screen center.

In both cases, this will always show when the TV is ON. Even if there is no signal being input to the TV. There are other possibilities but these can be the most common. Both require a new panel.

The only logical solution for the problems people are having for the toshiba regza's tv's is to get into a class action law suite..., they contiue to sell tv's with defective parts and refuse to help the customer that spent large cash to find out they last if your lucky 2.5 years, they are junk and anyone with one will soon find out./.......

This maybe the symptom of a bad Panel. One Vertically This line is 99% bad panel. Call your warranty provider or SONY tech support if purchased under 2 years.
