Re: pictureis very bright

With the brightness problem, first have you tried adjust the brightness on the menu. if not try to adjust it first if nothing happens set it in the middle. and if you are confident enough to fix the tv while the power is turned ON, 1.first open the back panel or back casing to expose its components turn it OFF first before opening it, 2. next if you have the schematic diagram of the (PCB) Printed Cuircuit Board find the variable resistor (VR) for brightness. if you dont have the schematics for the TV, try to find it on the PCB its a flat piece of metal that has 3 terminals and a rounded face that can be turned to increace or reduce resistance. it is mounted standing up. usually it is beside another VR for the horizontal control. it is labeled as brightness on the PCB surface. 3. when you have found it plug in and turn the TV ON tune it on the clearest channel that you can find, 4. and then using a non-metallic screw diver turn the resistance plate that would be the face of the VR first slightly turn it to the left then check the monitor for results you can place a mirror in front of the TV so you can check while adjusting the VR. just make slight turns on the VR Left to Right until picture is clear. **remember to use a non-metallic material to turn the VR to avoid elctricution. With the with white line problem or i usual call it the Stick. there is already a problem with some components on the vertical section on the PCB. it would be any of this parts the Capacitor, resistors, trancistors, and i would suggest that for you to have it checked by a technician coz it would be hard to determine which parts is faulty.

Fix color?

You may have a picture reset button available to you in your menu choices under display or picture. If not you will see a menu with color, contrast and brightness or something along those lines. With your remote make all of the settings for these the same with them set in the middle of the virtual slider. That will even you out and you can adjust to taste from there.

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

No Picture Has a bright horizontal line with off white & gray vertical bars

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.

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.

My resistors are not numbered the same on my crt board APT187. GSM 02/20/2008

White horizontal line down middle of TV screen

caution whenever you see horizontal line please reduce brightness of your tv for safety of crt. your problem in vertical section only mostly due to loose contact in connector,print or loose components.
