Lcd display malfunctioning

Glad you found the solution because I had never heard of the lcd locking.

Yeah, the problem is the screen more than likely. I would bet you have a loose cable on the lcd screen.You'll have to take the lcd screen apart to get to the cable that is on the back of it at the top. unplug it and plug it back in and secure it with a piece of tape where the connections meet. Unplug the other end of the cable and plug it back. Also unplug the two cables that go into the LCD Inverter that sits under the LCD Screen at the bottom, then plug them back.

Before you take the screen apart, try plugging an external monitor on the laptop just to verify that the video card is good. The display should show up on the external monitor.

This problem is most likely caused by the T-CON board. It could be a bad connection of the cable from the LCD to the T-CON board. or the T-CON board could be bad. Sometimes you can disconnect and reconnect the flat cable(s) to the T-CON board and solve the problem. Else you can replace the T-CON board.

The T-CON board is the board that drives the picture to the LCD screen.

There is a loose connection inside your lcd monitor. This is not a user-serviceable case. Proceed to your local service center. Pressing or applying pressure to your monitor may cause some more trouble and defect to your laptop. Goodluck.

I believe this is the one ...and In generalany lsc screen that will fit inside will do ..but the fitting has to pe perfect and the ribbon to be able to match ..this one I guess is teh original and it came with the all not just the lcd ..all you have to do is mount the ribbon on the board ..and the hinges..

The LCD is going bad, the replacement cost is about 200$ a ballpark figure keep in mind, first bring it to a repair shop and get a estimate, i usually don't charge for this. But this will depends on that specific shop that you bring it to. Good luck.

dust in the game console clean with wet q-tip the game and the ds

The display connector contact on the motherboard is loose. If you can open the casing, you'll see a ribbon cable from the LCD part connecting to the motherboard. The connector is usually rectangular and connects downwards. Try pressing it in firmly.

PWI17LS285A, ACTUALLY THE CAPACITORS DOES NOT KEEP ENOUGH CHARGE TO KEEP THE LCD WORK...

so the big capicitor needs to replaced? 100µF 450V

Rhondie3 - the flexcable and the LCD needs to be replaced.
