I have a sharp 70" aquos le650U tv. The picture is great most of the time. Every now and then the left side of the screen goes dark & edges in time delayed refresh. Is this a t-con board issue?


No. It is back light fault. Check and replace damaged [burned end] CCFL lamp/s. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced.

Screen switches on but image cuts out after 1


You will have to check the inverter transformer for open winding on the secondary side (common failure mode for the inverter ransformer), you can also have bad lamps due to bad soldering works on the end of the lamps. The transistors driving the inverter transformer check out OK out off the circuits?
See these pictures here for guide: http://s807.photobucket.com/home/budm/allalbums
I will assume that you have measured the DC voltage feeding the inverter circuits and it is OK (about 12~18VDC).
Post some pictures will help.

Dull laptop screen back light


You may have a faulty CCFL lamp. A faulty CCFL lamp may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering and/or with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight or a faulty inverter that supplies high voltage to the CCFL lamp. Usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Dark unreadable screen


If you see a dim image or flicking image on the LCD screen it means you have a backlight problem.
Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
