Turn on tv went black left line in middle horazontal


vertical circuit is out, some component failed. turn it on and when the line comes on hit the top of the case with the flat of your hand, if the line fluctuates or goes away you have a bad solder connection on the circuit board. if it doesn't make any difference when you smack it then something has failed completely. no user repairable parts inside.

KV27V22 has 0:00:00 then an elongated box with smalled box inside, can not get it off screane


You will need the remote that comes with the TV (Sony). There is a button called "Display". Hit the "Display" switch on the remote to go through selections - until "Display Off" is display on the TV screen. Then wait about 3 seconds, and on screen display will go away.

Blackout area on screen


Make sure the TEXT and CAPTION options are turned off.

I am not sure about the Sonny's, but on my Toshiba a black box appears when I inadvertently leave one of the close captioning (CC) on for text or captions on (such as CC1, CC2, etc.).

Unwanted rectangular black area appears on screen blocking 40% of picture


This could be the result of a partly shorted vertical winding on the deflection yoak.Since the line is on an angle and not straight across.

Hi there!

There may be dry joints in the Line Stage where the Line Transformer is situated. The move may have loosened some components off the board. If not familiar with TV Electronics please refer to a repair technician. Regards and good luck, JUS004

Theres a line threw my tv.


It has a problem in the vertical sweep circuit that puts a nonlinearity in its output and you see the glitch in the normally gradual sweep as a line. Since a hit upside the set seems to help, you should just resolder the whole vertical circuit area (doesn't take long) and see if that cures it. If not, start replacing the electrolytic capacitors in that area.
Hope Ya Fix It!

Lightning Strike, Plz Help!


Hi. The red line on ICS is quite normal it does not mean the part has failed. To be honest in most cases if a tv has been hit by strike it is a right off & scapped. What I suggest is to remove the main pcb & power supply pcb if its seperate & inspect the print side of pcb for signs of arcing tracking or burnt track. Repair any damaged track by cleaning off the coating to get at clean copper then solder wire accros to bridge the damage. Check the power supply resistors diodes transistors look carefully for any burnt components or components which are physicaly damaged. Check the line output transistor this will be near the large transformer with a thick red ht lead going up to the crt. Check all the components you can in the line stage look at all the ICS to ensure none of them have holes in them or have blown apart. Hopefully you find some or one if your very lucky that is damaged replace it & try your tv.
