Philips 32PS55 S321

Any time I am watching the TV it could be cold or warm, any bright or white screen, it shuts the TV off. well, it is still running, but in order to get the picture back, I need to shut it off and turn it back off. Any ideas on what this could be?

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.

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

21PT3324/71 Philips TV wont stay on

Try this: On the flyback transformer, raise the SCREEN voltage. There are 2 controld on the flyback - the top one is FOCUS and the bottom one is SCREEN. As the tube ages its emission decreases, and the computer monitors the tube's emission. When the emission gets to be too low, the computer shuts the set down. This is exactly like IK blanking in Sony sets, except Sony blanks the video and Philips shuts the set off. To set the screen voltage properly, turn the brightness and contrast to 0, raise the screen voltage until you see the white retrace lines in the picture, and then back down on the screen voltage until just past the point where the retrace lines are gone. Reset your brightness and contrast and the set should play fine.

Tv is too dark

You didn't say how old your TV is. If it's very old the picture tube could be weak. IF not then there is a screen adjustment on the flyback transformer that you might try to adjust. Sometimes you can access this adjustment without removing the back cover. If you see an adjustment through a hole in the back of the cabinet marked "SCREEN" then you might try turning this control clockwise while watching the picture in a mirror. Only a slight adjustment may be needed. Don't make it too bright or the set may shut down or have small white (retrace) lines in the picture. If you have a projection TV then dust on the three picture tube lenses will darken the picture. These are general statements that apply to different TV's. I assumed that this is a direct view 32 in.

Dark picture (HELP)

Open up the back of the set but be very carefull. Notice a large black block with a large red wire that runs up to the picture tube. on one side of that large block where the thick red wire is comming out of are two controls, one should be marked focus or F and one should be marked screen or S. With the set operating normally and not touching anything else, slowly turn the control marked screen or S clockwish till the picture gets bright enough. If you go too bright the set will shut down or you see small thin white lines so back down on the control. then touch up the focus and your good to go. good Luck.
