Jvc 27'' TV is too dark

There are two small holes on the rear side through which you can adjust focus and screen. Use a flash light and locate the two adjustable slots inside the holes. This part carries high voltage. Do not use a metal screwdriver to adjust. Put the TV facing a mirror so you can see how it works. Do not turn more than 1/8th of a turn. The focus control makes picture sharp or fuzzy. Screen control could change brightness. While watching the picture in the mirror, slightly adjust the screen control. Do not turn too much. If it doesn't work, then call a JVC authorized repair center.

I have a JVC 27'' AV-27530 TV that the picture is very dark

An aging FBT if it still can be adjust using screen adjustment on FBT that will be a small tweak.

But if you are inexperienced with this, asked someone who knows how to do it to fix it for you.

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

JVC AV 270305 Brightness not Bright enough.

Yes you could look for the capacitor that is leaky, probably in the 200v line, or you could just open back and turn up G2 screen control on the Flyback. You have Screen and Focus on this black transformer with a long anode lead going to the picture tube of set. Becareful, High Voltage!

Brightness of picture

If you feel good about opening your set then you can try this: Look for the flyback (high voltage) transformer, with the thick red wire which goes to the top of the picture tube. There are 2 controls on the flyback transformer, focus (top) and screen (bottom)Turn the brightness and contrast all the way down and then increase the screen control until you see retrace lines, and then back it down until those lines just vanish. Return the brightness and contrast to normal and adjust the focus control, if necessary, for a nice sharp picture. Let me know if that brings your brightness back.

Tv problem

I assume you get a picture in there somewhere? The discolorization is caused by the degauser circuit malfunctioning or un-shielded speakers sitting too close to the TV causing magnatism in the CRT (picture tube).

JVC 27" AV27F803 Brightness fades to dark intermittently

I likely you have a loose conection in the crt board at the neck of the picture tube or a loose conection close to the high voltage transformer,I would suggest to tap the main board as well as the crt board with a wooden or rubber handle(not metal),be attentive were you tap to see if the set reacts ,if the set reacts you will need to resolder those places ,be carefull working on a set that is on while you do it,this should give some idea what the problem could be in case you want to call someone to help you with the repair.Let Us know if you need more information.
