JVC AV-27730: horizontal bright line across screen in the


it could be an electrolytic capacitor or the vertical output I.C. in the vertical circuitry,if you remove the rear cover tap on the board in different places and see if the picture fills out or atleast jitters like it might fill out,then it could be just a cold solder joint,then remove the main board and resolder all joints and this should repair the condition you have

MY SCREEN SHOWS ONLY A BRIGHT LINE STRAIT ACROSS THE CENTER OF THE SCREEN


you more than likely have a coupling capacitor defective in the vertical driver/output circuitry,or you can have "COLD"solder joints in these or the power supply section,carefully tap in every area on the case,if picture starts to expand and collapse, then its a solder joint thats bad/if you can take back cover off take an insulated plastic instrument and tap and push on board and components to see if you get the same results...be careful inside case

TV: bright line across black screen for several hours.


vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch

Picture screen


Hello! You have vertical collapse. There are bad solder connections at the vertical output IC. I have repaired MANY panasonic tv's like this. Very easy to repair if you have any soldering experience. If soldering does not fix the problem you need to replace the vertical IC. Good luck

I would love to save the TV. Hi nothing to worry just minimise brightness to avoid screen burn. "Vertical Collapse?" means one bright hor.line in the middle of screen. this problem can be solved 1 check vertical yoke connector or wire loose 2 check supply to vertical section which normally comes from EHT transformer check components in vertical section or print loose regards thanks

Screen on rca tv compressed into 2 inch line in middle


The 20F530T uses the relatively newer ITC008 chassis. If the picture collapses down and only a small bright line is visible, it means that your vertical output IC has stopped working correctly. This could be due to a defective IC, cracked solder joints on the IC or the power supply that feeds it. The IC should be replaced or resoldered and/or the vertical power supply restored by an experienced tech familiar with the new line of RCA TV's.

Your problem is in the vertical deflection circuit. If you know how to solder it may just be a cold solder connection, but if you try to solder it and it still does not work, you may have a bad Vertical output IC. This set has really no user replaceable parts unless you have some no how on serviceing solid state printed circuit boards. If you dont , my advise would to seek out a repair depot and have them fix this set for you. It should not run more then 150 bucks or so. Good Luck Ps please do not forget to rate this thread.
