Re: help

Sounds like it needs to have the vertical circuit rebuilt it killed itself from continous attempts to restart with shorted parts in it

On power up I hold the power button down, I can hear some sort of relay kick-on, sometimes a horizontal white line appears across the screen, then it kicks-off, and the red led blinks four times...

White line across the screen indicates that tv got vertical deflection failure problem that may be due to vertical output chip failure. If that kind of problem occurred, tv select protection mode and red light starts blinking 4 times.
Please check vertical output chip in tv main board and replace it to solve tv issue. This job needs soldering work so local tv repair shop will help you.

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.

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

Rca 32 inch tv

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.

time to buy a new tv

TV picture went out. stand by/timer light blinks when I turn on the TV. no other response from TV.

The timer light blinks representing the fault on the tv. If the tv blinks in an orderly fashion then the number of blinks before pausing is used to indicate the fault. This can only be determined by looking at the service manual for that set. If the blinking is continuous without pauses after a number of blinks, then it indicates there is a problem and the first place to look would be in the power supply. Either the power supply isnt supplying power to the Line output transformer i.e an open circuit or short circuit..OR the line output circuit has a short. Without a diagram i cannot guide you which components to check..but..swollen topped capacitors in the power supply are a give away :)

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

    A bright line on the screen

    A line running across the screen like that and then returning to a picture I would guess is the vertical IC has some poor solder joints. The vertical IC in that unit IC401 is an LA78041 a seven pin IC that is mounted to a metal heat sink. On the foil or under side of the board take a careful look at the pins of that IC and any that look suspicious carefully re-flow some solder over.. Careful not to keep your iron on the pin too long.. And if have to re-solder several take some time between them to allow the IC to cool so you don't damage it.. Good Luck Bill
