Check the panel voltages, and start unplugging the cables to each PCB and check the voltages each time, if the voltages come back up the its probably the PCB that is disconnected, in most case its the logic main board. Hope this helps

I was able to resolder the pin shown in the picture and it fixed my problem as well.  I also used a razor and cut off the last socket for that pin on the connector and put a dedicated connector on so that it will take the heat a little better.  Also when I re-soldered that pin on the bottom side of the board I scraped away some of the protective coating around the solder puddle so that I could make a bigger solder puddle to add a little more strength and heat resistance.

I have a 46" Sony Bravia TV that has colored verticle lines about 2-3" wide just left of center.

Yor tv have problem with T con board. T con board is one which drives the pixels of the LCD panel. If any of the driver satge in the T con board is faulty then this problem can occur.

Some times bad contacts on the connections of the t con board can cause same problem. Remove the tv and find out the t con bard. Remove the connections to it and the reconnect the connections. Then check, if the problem remains the same then the tv need a new T con board.

You have didn't mentaioned any model number of your tv. So it is not possible to show you exactly how T con board looks.

Normally in all lcd tvs the tcon board is place on the bottom or top middile position. Which will be cover with metal cover or aluminium foil.

Here I have added a link which will lead you to the picture of T con board for toshiba.( Not exact one)

Two of my wires inside my computer came undone one is the power led and one is power sw where do they go? thank you

The Gateway GT5408 Desktop PC uses an Intel (Council Bluffs) 945G Viiv motherboard,

Left-click on Components in the list. Scroll down to the heading - Motherboards, and left-click on -
4006160R - Intel (Council Bluffs) 945G Viiv Motherboard

The front plastic cover of your computer is the Front Panel.

The area of pins on the motherboard, that the cables (Wires) from the Front Panel go to, is the
Front Panel Header.

Motherboard installed in your computer, with the Processor to the Top, and Ram Memory slots to the Right, the Front Panel header is at the very bottom right corner.

It is a rectangular block with pins in it, and lays horizontal to the bottom edge of the motherboard.

Left-click on Product View in the list.
Now left-click on, P-Front Panel Connector

As you can see the white rectangular block has 5 pins across the Top, and 4 pins across the Bottom.

The pins are numbered.
They are numbered Odd across the Top, and Even across the Bottom.

Starting at the RIGHT side going across to the Left, on the Top row;
Pins 2, 4, 6, 8, and 10

Starting at the RIGHT side going across to the Left, on the Bottom row;
Pins 1, 3, 5, and 7. There is NO pin 9.

A) Pins 1 and 3 are for the HarDDrive activity LED light.

Pin 1 is for the Positive wire ( + )
If the HDD LED light is dim when operating, switch the wires around.

B) Pins 5 and 7 are for a Reset switch, (Reset button), IF used.

C) Pin 9 is for a +5 Volt wire. I don't think it is used, but you have the computer, and can correct me if I'm wrong.

D) Pins 2 and 4 are for the Power On LED light.

E) Pins 6 and 8 are for the Power On switch.

F) Pin 10 is N/C. Not Connected. (No kidding Gateway, since there is NO pin there!)

Remember, RIGHT to LEFT.

For additional questions please post in a Comment.


(P.S., I took you the 'Long Way', so that you can have other information about your computer, at your fingertips )

Hi, I own a 50 inches plasma LG tv (the model is 50pj550) for only 2 weeks and it has started giving me 5 green dotted lines 9consisting of green pixels), from top right corner to bottown left corner....

Sorry to lay some bad news on you.........

It sounds like your set has had defective silk screening during the manufacturing process.

The lines in a plasma set are laid out using a silk screen process, the defects (if any) are burned out by laser, then the surface is sealed to protect the lines with a vacuum coating process. Your set sounds like it had a manufacturing defect that quality control somehow happens!

The good news is that since your set is brand new, you should be able to exchange it. Don't delay!

Their is a big black line down the middle of the tv from top to bottom, from the time i turn it on to the time i turn it off

Most likely your speaking of dead pixels. No real solution other than if it is still under warranty they could replace the panel.

Sorry pal.

Which connectors are used for front panel, power on (red @white) and led ( blue @ white) please show a close-up view

On the motherboard the pinouts on the front panel should be colour coded, and marked with letters like in this picture >>>>>

The connectors are also marked corresponding to where the connect on the motherboard, like in this picture >>>>>>

If the board is not colour coded then the motherboard will marked with the same letters, you may need a strong light to see the marks.

Gateway P41M`01 Picture off the top and bottom

You should have a button for "aspect ratio" (unsure of your brand of tv), could be marked "screen size - picture format" etc. Cycle through the sizes with this button until you come to auto or wide (set to auto to adjust the pictures to what is being transmitted - wide for a full screen but will stretch the picture to fill when transmitted in 4:3 format)

Blue Noise/Pixels Bottom Left Corner of my Samsung Plasma

You would need to have a technician remove the back of the TV and make the adjustment. There are 2 small adjusters that they change to adjust the voltage.
