Hello, I have a Hitachi 42 inch plasmas, model number: HD42S69. I have a 3 inch thick vertical red line, left of center (if your facing the tv) that sporadically appears, but often. I took it to a repair shop. The guy told me that its not the control board and it isn't the display panel, it's a buffer board. He wanted $200 and he said the part is like $60. I figured I can just do it myself, but I don't know where the buffer board he was talking about is? Can you help me locate it? How do I even know what board is causing the issue?

Re: Vertical Red Line appears on Hitachi Plasma HD42S69
A-BUS = X-buffer (Address buffer)
The problem is simply the connector. Just unplug it and plug it back in. You -may- want to use a little contact cleaner.
Do not make any change with power on!! The power must be off, or you could damage the plasma panel! Damage to the plasma panel is not repairable.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

You can buy a small spray can at local electronics shops. After applying the contact cleaner, wait around 10 minutes for it to dry out before turning the set back on.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Spray the whole board, or just the connectors on the board?

Just the suspect connector. Spray it on with the connector unplugged.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

They probably will. Other places like Fry's will stock them, you can also order it online if you are prepared to wait a few days (will cost a lot less too.)Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Here's a picture of it. Can you tell me what connector(s) is causing the issue?

Whichever side/connector the line is on. It looks like each connector drives two halves, each half being one sixteenth of the panel.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
