Hi,

Your posted description is a known (common) problem for the JAV-27230 and should be easily repaired. The vertical capacitor (C424 - 100uf/35V) needs to be replaced. It is relatively cheap and can be bought from any electronics parts store.

in some instances, it could be the vertical IC starting to fail or even a simple case of cold solder.

As always, extreme care when repairing the insides of a TV unit since HV can still be present even when off and unplug. A little knowledge of electronic components and use of a soldering iron should do just fine. Should you not be comfortable doing a DIY, then perhaps you can ask the assistance of a buddy who has some soldering experience.

Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.

good luck and kind regards.

JVC AV27230 had a bright white screen with lines across it. now just went black


You may have a power supply issue and at the flyback transformer .
There also may be components in the circuit surrounding the fly-back that are malfunctioning.
The issue points to a repair at the board level. A tech will be able to determine this with test where the issue is on the main board.
I hope this helps.

HORIZONAL LINES


that is because you have a defective vertical deflection circuit, check all the caps and if that does not solve the problem replace the vertical output ic

good luck

31'sanyo tv analog has a white horizonal line thru it


There is a failure in the vertical amp section. This can be the main output IC, or any of the support components in this area.

An experienced tech can troubleshoot the set, and determine and service the fault.

Horizonal line


I think you have a fault on the picture frame board. If you can check for this yourself or find a competant technician. Hope this helps.

Thin horizonal line in middle on dark screen


The several thin white lines at the top of the screen is the warning that the vertical output IC is not getting the boost voltage it needs to run correctly. The IC cannot operate for long like that and shorts out inside, which is when the vertical collapses altogether and you get the thin white line through the center of the screen. The good news for your son is that he had nothing to do with that, and it has nothing to do with the cable F connector. The set needs to be serviced by an experienced tech who will restore the boost supply and replace the vertical output IC, and when I do that I charge $75 but techs in your area will vary, so be sure to ask around.

RCA 32V420T 32" TV


This RCA set uses the CTC187BD chassis. Look on the back of the set and to the right of the cable connector you will see 2 controls sticking out, one on top of the other. The top control is for focus and the bottom one is screen, or overall brightness. If these controls have been turned clockwise then you will have a bright, fuzzy picture with white lines (retrace lines) through it. Tune in a channel with white letters on the screen and turn the top (focus) control until the letters are crisp and sharp. Go into the menu and turn the contrast and brightness all the way down, and then turn the bottom control (screen) until you can just see the picture, just above the point where the picture is too dark to see. Go back into the menu and reset the contrast and brightness and the picture will be back to perfect.

Horizonal White Line


Your problem could be one of the common ones as this set has loads of bad solder connections. Your problem is most likly the verticle output IC connections or the B+ feed componets have bad solder connection on them. In some cases though the Output IC is defective and will need to be repalce. if you have no soldid state repair or soldering skills play it safe and get a pro to assist you in this repair. It should not cost you more then a hundred bucks or so and thats the high end. good Luck, And Merry christmas.
