MY TV TURNS ON BU NO PICTURE OR SOUND. CHANGED BAD CAPACITOR BUT ONLY GET SCREEN WITH A GLOW


You have a bain Main A/Vboard. The screen has a glow means that everything else is functional including the backlight inverter. Replacing the main A/V board should resolve the problem so let me know if you wish to fix it yourself.

The screen is black. I have sound but no picture.


Hello,
If everything else works - there is sound and high voltage (static on the screen) - but there is no picture (including no on-screen menus), this limits the likely area of problems is the video output circuitry or CRT filament connections. Check to see if the CRT filaments are glowing. If they are not glowing, check for bad soldering on the CRT neck board and around the flyback transformer.

Where the picture is erratic - coming and going entirely or changing brightness suddenly, with power off, remove the picture tube socket (carefully!) and clean the pins with fine sandpaper and use contact cleaner on the socket. This source of bad connections can result in a variety of erratic symptoms. Check for bad solder connections on the CRT neck board.

Everything in picture has a red outline tried


Howdy,

It sounds like you are having a problem in the conversion circuit. The outputs IC’s for that circuit have failed and are need of replacement. The average cost is at least $450 on one trip. Call an Authorized Service Dealer for repair and estimate.

The conversion circuit is the circuit that aligns the picture.

Good Luck, Big Irish.

Monitor has a red outline especially on pictures.


Probably there's an internal electronic part/s of your monitor that is cold sholdered or defective. I suggest to bring the unit to an authorized service center to properly diagnose & fix the problem. regards

Philips big screen projection tv


sounds like the Convergence ICs are getting ready to go. Does it appear as a outline almost 3D? If so its convergence if its more like a glowing halo its coolant in the blue CRT that needs changing.
