Question about JVC AV-27F702 27" TV

1 Answer

JVC 32" flat screen I Art AV27F702

Please Help! There are several rows of dash like horizontal white lines at the top of the tv. Some of the lines are steady and some flicker? Sometimes there are more rows than other times. At first they were only there sometimes but now they are there all the time. What could be causing this problem? I tried all the connections as I thought maybe it was some kind of interference but to no avail. If anyone has any kind of idea, I would greatly appreciate your help. Thanking you in advance, Lady D

    1. Hi,

    My jvc tv AV 27F702 has the same problem, as you said change C410 (vertical section) with 220uf/50v, but i check the capacitor on the pcb is Metallized polyester film cap and written: 104j --- 2A. Is it the right location that i was looking or the wrong location, is it the V-OUT is the vertical section? i do not have the schematic, i need help, thanks.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Sounds like retrace lines. Leaky caps or worse can cause this.. Are you getting any vertical foldover at the top of the screen?

1 Answer

Several dozen thin horizontal white lines across the top of screen, all channels


These beasts are monsters to get into and service without the proper extenstion cables and a service manual. there are no user replaceable parts inside this set. if you know solid state serviceing, you can try and fix it. There is a bad capacitor or capacitors in the vertical sweep circuit and or the vertical output IC is bad also. If you can solder and unsolder go for it. But if you do not or know how the circuit Works Please find a trained tech to assist you with this repair. Good Luck. PS please do not forget to rate this.
