Hello Geddy Lee, for what you describe, it could be a problem on the T-Con board

Hola Geddy Lee, por lo que describe, podria ser un problema en la placa T-Con

SOURCE: 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.
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
Sincerely

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

YES YOU HAVE DRY JOINTS UNPLUG FROM POWER SUPPLY REMOVE THE BACK/ INSIDE YOU SHOULD SEE AT THE BOTTOM SEVERAL RIBENED CONECTORS FROM THE SCREEN ITSELF? UNDERNEATH YOU SHOULD BE ABLE TO SEE 2 OR 4 COMPONENTS CAREFULLY APPLY A HOT SOLDERING IRON AN SOLDER THE ONE THAT YOU ARE HAVEING PROBLEMS YOU SHOULD NOW HAVE FULL PICKTURE AGAINE ANY PROBS email me [email protected]

I have this problem on my CPX985w, almost exactly as you describe, I'm going to pull the main board out and check the capacitors, as that seems the likely problem, i'll update with what i find....

You could have one of three problems. One is really expensing to fix and you might want to trash the set. Thats if the panel is bad. Secondly, it could be a buffer board that went back. Not as expensive as the panel. Finally, it could be the connection between the two. I would first take the back off and locate this board. Undo the ribbon cable and clean it off a bit and put it back. If its still there, you have a deeper problem.

it seems to be a bad connection somewhere but I disconnected the ribbon cable and got a verticle line of snow instead of a blank line. the line is about 34 mm wide and starts 285 mm from the left edge starts on the Blue and goes to the Red pixels. so if they are 1mm wide that would be 34 bands of color.
I would sure like to figure out the solution to this one or I got a TV I need to throw away cause the o'lady is gonna bust my balls if I can't fix this!
