Left side of my dell w2300 lcd tv has vertical lines

The vertical line are mostly caused by a defective LCD panel.

Either LCD transistor got moist or the video chipset got condensation. Keep TV on standby to dry it out. Unless there is also mechanical damage to the lcd screen on the edge..

It can be the LCD controller board, or worst case, the LCD panel.

First place to look will be the power supply module, look for blown fuse, burnt parts, bad capacitors.

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...

sorry for this bad news your screen is going bad and it cost more than a new tv sorry

good luck

hey if you want o sell it busted email me m[email protected]

the unit needs to be opened, and the power cable needs to be removed for 1 minute, then reconnect, reasemble, u should be ok.

Your problem is due to intermittent power in the backlighting circuit. This is usually caused by swelling of electrolytic capacitors in the power board. If you can find an honest electronics technician it is about a $40.00 fix.
