I just hooked up the tv and there is a narrow vertical white line down the center of the screen. the left side of the screen looks normal but the right side of the screen looks to be moved down just a little bit. what is the problem?
Check and replace all the electrolytic capacitors at its vertical output section circuit.
SOURCE: Audiovox AVT 1598
The vertical output IC or the vertical circuit is whats at fault. its all solid state and im sorry to tell ya that its not a user replaceable part. This set is probably not worth the repair it would take to get this set working again but please if you like ask a ;ocal repair shop what they thought about this problem.. Good Luck and please dont forget to rate this thread
SOURCE: 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!

The Problem
Philips 27TS54 c101 27B800-7562 White horizontal line in the center of the screen. Color is present in the first half inch of the leftist corner of the horizontal line.
Audio is present and controllable. The green power led from a cold non plugged in state remains solid until CRT goes to ignite. A click is heard then the green power LED blinks.
I found service manual diagram of repair part or parts and install instructions

I request any info or tips you might have pertaining to this problem
Thank-you

On the CRT circuit board(picture tube), you will find R3340, which is a 10 ohm 1/3w resistor. The location of the resistor is printed on the bottom of the ckt board. It is burned open, replace with a 10 ohm 1/2w resistor. This will solve your problem. The original resistor was sized too small, should have been a 1/2 watt. This resistor is mounted standing up on ends. Mount the replacement resistor the same way. Be careful and don't get the circuit trace too hot and damage the circuit trace. (it's very small) The resistor is located on the crt(cathode ray tube), pcb(printed circuit board) socket. The resistor supplies apx +200v to the collectors of the r, g, b, video driver transistors. If this voltage is low, it causes excess brightness(excess beam current), causing the set to "shut-down". If the shut-down is too quick, you will NOT see the excess brightness, because the picture tube has not warmed-up enough to display anything on the picture tube. To see if the set displays "excess brightness", you will need to turn the set "on" about 5 to 10 times. This will heat the picture tube enough to display "excess brightness", IF that is the PROBLEM. Of course, there are OTHER defects that will cause a tv to shut down. There are built in safety circuits, that will "activate" if excess voltage/current or heat is detected anywhere in the set.
NOTE
My resistors are not numbered the same on my crt board APT187. GSM 02/20/2008

if these lines are just at the top of the picture then i would suspect an electrolytic capacitor in the vertical circuit.
