    The screen goes black, with a think horizontal blue line in the center. The audio still works, but changing channels the channel numbers do not pop up nor does the screen change back after turning on and off. I tried taping the sides and the top of the television, but it doesn't help. Is my television dying? I've had it for over nine years.

The intermittent horizontal line is cause by a loose solder connection in the vertical amplifier IC.
The IC is mounted on a heatsink nearby or around the flyback transformer.
The way to fix this failure is to add fresh solder where you see some brown spots on the circuitry that were cause by components getting hot.
Good Luck.

TV has a great picture but wont "hold it". Keeps going to a single flat horizontal line across the middle of the screen. Tapping on side of TV used to bring it back but now, nothing. Just a line.


Vertical scan output section circuit fault. Absence of vertical scan causes the single horizontal line on screen. Horizontal scan output section is OK. Contact any service technician to troubleshoot the vertical scan output section circuit. If you wish to get some details; check the site linked here. Pull up older posts.Surf the site with patience.http://electronicshelponline.blogspot.com/

No picture no sound


Did you mean the picture is collapsed only in the middle horizontally(white line appears on the middle part of the screen)?
If that is the case, maybe vertical IC failed or loose connection.

Horizontal Line through middle of TV screen


This is usually a bad elect capasitor or a bad solder connection on the vertical IC, The capasitors will be close to the vert chip..Sometimes you can clear problem with a light tap on the TV, if so then suspect bad solder.

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

the problem there is a loose connection on the board,you said that you smacked the right side of the tv and it goes normal.there are parts that should be resolder on the board in order to back into normal operation.

TV goes black at bottom and has horizonal lines in middle?


Hello, please check the high current area around flyback transformer, horizontal output transistor as well as the deflection connector for bad soldering. Best regards, Arpi If you need more info please advice.

No Picture On Screen and red line in middle.


The set has a vertical problem if the line you mention is from side to side ,if the line is from top to bottom the problem is in the horizontal circuit and both can be repairable,a vertical fairlure is a common problem,the vertical IC goes bad and it takes a safety resistor with him to prevent any more damage,the horizontal is rare but it happens too,if you are familiar with tv service you can change the IC but you will need a service manual to identify the part,you can get a manual overnight if you downloaded it at www.servicemanuals.net,if you are not too familiar you should seek the help of a servicer for safety reasons.Let Us know how it goes or if you need more information.

RCA 27" F27189ET HOME THEATRE - No picture


Is unlikely the picture tube is bad,the description of the problem tells me you have a straight line from top to bottom that is an indication of a horizontal deflection problem and is correctable and inexpensive,just in case the line you mention goes from side to side the problem will be in the vertical circuit and is also repairable.To make things easier tap the set on the side just to see if it reacts,don't over do it ,if it does the should be a lot less expensive because it might just be loose conections.Be safe and call for assistance.
