Question about Standard (CRT) Televisions

Picture on RCA TV shrinks to a horizontal line


While watching programs the picture would disappear into a horizontal line across the middle of the screen and then go back to full picture. Now the TV only shows a horizontal line in the middle of the screen. This is an older 35 inch home theatre model. Is this worth trying to fix?

    Am I the only one worried the original poster never responded because he was shocked into a coma or worse?

Hello,
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

JVC picture turns into a single line in middle of screen.


This is caused due to random falure of vertical scan circuits. It generally is caused by dried out capacitors or bad driver IC. Unfortunately it will get worse. If you fail to turn the TV off quickly you will burn a permenant horizontal line on the tube. Trip to the repair shop I am afraid.

this is a frame fault
the fact that you can still see the line when the tv is off is because you have been watching with the line and it has burnt into the crt.

RCA Entertainment Series 32" Plus Gold, GEMSTAR, xbox ready has been in the shop twice so far. Transformer replaced and 6 months later the picture suddenly had horizontal white lines that gradually spaced apart more from top to bottom and it had a gray hue and fuzzy, but I still watched it for 3 months that way. Today I turned it on and about a minute later I heard a loud crackling sound coming from the back and the picture disappeared, screen went black. Is it worth fixing again?

Picture is black except for colorful horizontal line across tv


It sounds like you need a DEFRAG Done. Have you put any new speakers or magnets near the TV? Has anyone had a magnet toy or things around the TV lately?

The vertical output IC LA7847 is failing. It will likely fail permanately and you will have just the horizontal line. The set will require service. Just do not run the set very long in this state. That thin white line can likely burn into the crt phospher and will show all the time thus ruining the glass picture tube...

Problem with tv


Could be a horizontal output fault, faulty power supply, a simple dry solder joint or HVT. If you can hear arcing or smell an ozone odour, it will be the HVT which may cost a bit.

Without knowing the actual cause, it's impossible to say how much it would cost to fix it.... could be anywhere from $50 to $250 etc

Best to have it checked by a technician and get a quote to repair... then decide if you think it's worth it.

Toshiba is generally a reliable brand, so if you were happy with the picture quality before the fault occurred, it's probably worth repairing.

Tv not working


this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!
