The picture on this set is now a vertical line in the middle of the screen with a sliver of the picture showing. Sound works fine and can change all the channels.
Does this mean the picture tube is done for? And is this worth fixing?

Re: 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.

Hello The vertical sweep section of your TV is faulty. It may be either to a loose solder points at somewhere in that section of to the fault with the vertical output IC. Check all the solder points on the vertical output section of your TV. It is best to resolder most of the suspected soldering points, by applying a little more solder, without making any solder bridge short in between adjecent solder terminals. If this does not help you, replace the vertical output IC with same type and number. OK.
this symptons is caused by a breakdown in the vertical deflection circuit. hence, the trouble may be in the vertical oscillator, amplifier or output circuit. in most modern tv the vertical ic is usually composed of these said circuit inside. the ic have many pins, standing on a heat sink and smaller in size. try to check also the capacitors surrounding it. sometimes leaky capacitor may cause this problem. good luck!
There must be a fault in the screening of the internal wiring to the scart outlet in the home theatre system. I simply changed the way the player was connected to the TV and the interference disappeared:-
1.) I used the RCA video outlet instead of the scart lead. Picture quality was not compromised. FYI the Panasonic Plasma TV I have has only RGB video input sockets at the back, so I used a scart to RCA adaptor to overcome this problem of connecting old technology to new.
2.) The surround sound when playing DVDs is generated directly from the home theatre system so there was no need to connect the audio from the home theatre system to the TV
3.) I used a pair of RCA leads to connect the "audio out" from the TV to the "audio in"on the home theatre system to provide the option of TV sound through the home theatre system.
Sounds to me you have a cold solder joint ( loose solder connection ) on the printer circuit board around or on the vertical chip or on one of the vertical capacitors. You may also have a bad vertical chip or a bad vertical capacitor, but I doubt it since it did come and go. I'de get a soldering iron and some solder and touch up the connections. I will remind you that you need to always excersise saftey by making sure, before removing the back, unplug the TV from the wall, and use care not to come in contact with the large red wire going to the back of the picture tube as the picture tube can be turned off and still store lots of voltage ( up to 35,000 volts). Always stay safe and when soldering, use care not to run solder across places that will make a short.
Good Luck and I hope this helps

The thin line means you have no vertical sweep. the popping sound was the vertical capacitor(s) or the vertical driver IC blowing up. this happens sometimes out of the blue and almost always when you first turn on the TV set. if you cam solder, Get a schematic diagram, then you should be able to trace out the curcuit and replace the defective parts. If you have no solid state repair experience, you really should take the set into a shop or have someone estimate the set for you. If you do have any repair experience, and can send me a schematic of the circuit I will be more then happy to assist you find out what the problem is.
