Question about Hitachi 61SDX01B 61" Rear Projection Television

3 Answers

Multi colored vertical lines - aspect ratio - on screen menu

I have three problems.
Problem #1 - At times when I turn on the tv, multi colored vertical lines appear across the screen. I have to turn the tv off, then on and the picture appears.
Problem #2 - I have the aspect ration locked it at 4.3, however at varying times it changes by itself to 16.9. Plus the picture sometimes disappears and reappears when this happens. Sometime it does this three or four times in a row. I then have to change it to 4.3 using the remote.
Problem #3 - The volume on screen indicator and all the menu items used to be in solid colors and readable. Now everything is broken up and hard to read.
Any ideas of assistance will be appreciated. Thank you.

    No HDMI hookup. Main hookup is component video cables. Prolem #1 has been going on for a long time. Problems #2 and #3 within the last few months.

Try hooking up a dvd player to the aux option and see if the lines still appear and see if the volume and the menu items are broken. If they do, you may have to get a new color video tube or a video output board. You will need to get this checked by a professional to get this repaired.

    Try doing a full tv reset by unplugging all cable cords and power cords and let it sit overnight. Then check it in the morning and see if anything changed.

Can you tell me if you have devices connected (like a cable box) via HDMI? It sounds like your aspect ratio change, color lines and loss of pic could be related to a handshake probelm on HDMI with a cable box

    OK It sounds like you may problems in the DSP section (digital signal processing) which processes the video before being sent to the display tubes. The fact that you are also seeing problems with the OSD and menu displays leads me to this conclusion. The incoming signal is converted to a digital signal then the OSD and menu info are added and then the signal is sent to the display. In your case, since your display is analog (picture tubes) it has to be separated into the 3 colors and then converted back to analog and sent to the tubes. You are going to need a technician to narrrow down exactly where the problem is occurring in the DSP section.

How to fix Multi color Vertical Lines on a Vizio E470i-AO TV


Does the menu function display the same lines? What kind of cables are using ? (HDMI, Component vid, S-video, co-ax)
Were you as tenacious checking all cables/connections as you were the electronics? Lets rule out this all too often over-looked possibility.
Do you still get the lines with nothing connected to the TV? (no source connected)

I have multi colored vertical lines across the entire screen. The menu screen is perfectly legible when selected on the remote and will go on and off like it is suppose to.


If this tv vertical colors lines problems happen by itself,tv problems not causes by u or an object by hitting forces to the tv LCD screen panel itself.The tv board that call the T-CON board it is dead,this board sit in the bottom in the middle of the LCD screen panel.Must be replaced the T-CON board to solve tv vertical colored vertical lines.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish T-CON board for the replacement.If causing by u or an object by hitting forces it to the LCD screen panel itself.The tv not worth a whole tv anymore,because by replacing the tv LCD screen panel will cost the same as a new tv.

Flickering multi-colored line in the middle of the screen.


You have a failure in the vertical deflection circuit. This could be either a bad vertical chip, the power supply that runs the chip or a bad capacitor in that circuit. This is usually a repair best left to a professional. There is a small possibility that it could be bad solder connections. If genlty tapping the unit temporarily solves the issue you can try and resolder the pins on the vertical chip LA7841 is the part number. There is also a resistor 1 ohm 1 watt. If that resistor is open you can assume the IC is bad
