Philips 42 in. Plasma shut down

My wife was watching tv today and the screen started flashing colored blobs. No discernible picture was coming through. Can't open menus. After 10 seconds TV goes blank. Green front panel light goes off. Red panel light starts blinking (7 times...pause...7 times...). Have to unplug TV to get power fully off. Can't get picture back up. Audio was fine, but seems to be gone now as well...

HELP appreciated.

    As I AV+ through to DVD, etc., the same problem. I disconnected all inputs (coax, Dish receiver vid and aud., side input DVD) just to see if I could get the menu up. No luck. Just the flashing pixel mix...

    I am a Tech in NZ.This is a common failure of this model.The only solution, we are told, is to replace the PSU. If anyone has a better fix I'd love to know as these PCB's are very expensive. Apparently Samsung who make the boards do not supply any circuit information.

    Had TV for 2 years with no issues then it just shut down.

    It now displays the 7 red flashes on the front panel LED.



    Tried unplugging for a day and the TV trys to power up but shuts down in about 10 seconds or less.



    Prior to this occuring, the TV would have intermittent issues with not displaying the bottom portion of the screen for several weeks.



    Anyone know what it costs to have the PSU replaced or if the part/board can just be bought for self-install ?

I have the model Philips 37PF7320A/37 won't turn on and MOST articles on the Internet say it's the Capacitors capictors capictors..I checked all of them. My tv just blinked red lights, had the clicking sound at first power on, but then goes black. No sound. No picture. Nothing. Just blinking red lights.

MINE WAS RESISTOR no. 3318 , a 100 OHM RESISTOR ON POWER SUPPLY BOARD.

I BOUGHT REPLACEMENT FOR .99 CENTS SOLDER IT, AND EVERYTHING WORKED!!!

THAT WAS ALL IT TOOK.

JUST A SUGGESTION..
1. CHECK FOR BULGING CAPACITORS (90 PERCENT OF THE PROBLEM)
2. THEN CHECK FOR RESISTORS WITH MULTIMETER ( FALLS INTO THE OTHER 10 PERCENT OF THE PROBLEM.)

TELL ME IF THAT HELPS..normanw1@yahoo.com

The LED blinking 7 times is a code to tell the service tech what is wrong with the TV. From what I've read at other sites it sounds like there;s a good posibility that it is a power supply gone bad.

You probably should call a TV repair shop for assisitance.

Screen Problem


hi....Your tv picture is managed by several boards, the two specific ones are the ysus and the xsus. The Y controlls the horizontal pixelation and the X the verticle, if you are having horizontal problems then its the Ysus thats faulty, on this particular set, the Ysus board has two accompaning buffers that are particularly troublesome. I've had more than one of these sets in the shop recently with the same ailment.Sounds like your buffers are starting to go out. The screen is split horizontally by the two long skinny buffers attatched to the Y main, if the bottom one has one leg in the grave you'll be getting a partially black screen or no picture at all. The colored lines running through the screen are more typical of a failing buffer. Are you interested in taking this set apart and putting a couple hundred into fixing it?  When buffers go they usually take the Y main too. Worse case scenario you're gonna be out about $350 dollars to fix it yourself. Best case, a ribbon is loose on the bottom buffer and with a dismantle you'll be able to connect it again..

thank u rate me!!
