Thanks for using FixYa. From what you have described it seems either the T-con board in your unit has gone bad and/or it is not getting the required 12vdc from the power supply unit. If you have knowledge of internal circuitry of the unit then you can open the back of the unit and check the T-con board which is the last board before the LCD panel. Usually it is available with the LCD Panel. Unfortunately replacing this is only recommended to be done by someone with electrical expertise. Please do accept the solution if the issue is resolved or post a comment for further assistance.

    The TCON was my thought too. I have replaced them before. Now It's trying to find one! As far as I can tell it's getting 12V (11.95). I am hoping it's not a defective panel.

Sony KDL46S4100 when turned on there is no picture just a blue screen

Is this blue screen on all inputs (HDMI, etc.), or just on the one?
Does the remote control work, can you get the menu to display, is there any sound?
If no sound and picture, no menu etc., might be a software problem, the main PCB, or a missing voltage on this board.

Sylvania lc320ss8 horizontal bar discoloration

Do you have tv repair exp. If not then take it to a shop.If you do then reseat the plugs on the T Con board ( Timing Control). If that don't fix it then go on E-Bay and get a price on a used T-Con board and try that. Those boards have a high rate on going bad.

Samsung TSL2793HF - Slight Right Side Pincushion and Horz Line Bottom to Top Until the TV Warms up

Yes, this is rare but I have seen it before--not fixable if it is what I think it is----It is what is called a Dome effect---the shadow mask in the picture tube is actually contracting and or expanding depending on temperature---

Directly behind the phosphor coating (the stripes that you see on the screen) is a metal screen--the holes or perforations in it line up with the stripes on the phosphor screen.

Some masks either have a material or a defect causing the dome effect----Not likely to be anything else---a Pin amp problem will not usually act the way you describe but a shadow mask inside the picture tube will act exactly that way.

Picture shifted to left 1/3 and left portion shows on right side 32" sony trinitron (not flat screen)

Probably caused by a failure of certain bipolar electrolytic capacitor(s) in the area of the high voltage circuit.

57" 2003 sony non-xbr projextion

there's a lot of talk in the internet that the pots in the front of the tv will take these (horizontal?) lines out . i have the kp-57hw40, and there is a web site with pictures on making the adjustment. i believe the bottom 3 pots are blue, green, red going from left to right. mark the pots first so you know where you started, and they say it takes just a hair adjustment counter clockwise to remove the lines. Only go to the point the lines disappear. web site shows how to get front cover off via two screws hidden in bottom and then take off the cardboard cover to get at pots. Not to be smart, but don't be careless, keep hands out since there are high voltage circuits just inside there. . . .
