    i didn't see any swollen capacitors on the power board. How would i check the voltages?

    Did you try another input like DVD player to eliminate the tuner as the problem?

  • Anonymous Jun 20, 2015

    No. All that comes on the screen is solid white. No menus interface or anything.

    Most likely the Tcon board is junk...

I would verify the voltages on the power supply board first because an improper voltage to a circuit board may make that board look bad.

    You need a DC voltmeter. This must be done with the power on, and I do not recommend doing this if you do not have experience working on powered equipment. You could get hurt or damage a good power supply board.

White screen, can only see shadows of the picture


Hello
Its backlight is not working. Check the CCFL tubes, and it backlight inverter board for fault.
Backlight inverter board will look somewhat like this. If this board has damaged, CCFL lamps won't light up, and there will be no backlight. OK.

When tv turned on will get apicture for only a few seconds then screen goes black, but wil continue to have audio. Cannot pull up menu on tv either


Hello.The screen goes black means that the backlights of your LCD is not working.Maybe the problem is the power supply or the driver board of the backlights.They shutdown because there have a shorted parts on the circuit or power supply. Did you try to reset the power and turned on and get a picture or every time that you reset the power it will get a picture and the picture goes black?

I suspect that you have a backlight issue. The backlight is not getting sufficient voltage usually due to a malfunction of the 12V line on the power supply board of the tv or a faulty backlight inverter board. This issue cannot be narrowed down any further without testing it. So if you are handy at fixing electronics stuff and know how to use a multimeter then let me know and I will guide you.

My audio works fine but no picture.I was told to check the fuses but dont know where the fuses are located at


The slow-blow white fuse is located nearest the point of where the power cord of the tv first contacts the power supply (middle-board, usually)

However, I would suspect the backlight inverter is faulty:

I would try to look on the power supply first for popped capacitors that supply the 24v rail for the backlight inverter.

Having sound is a positive when it comes to repair. This means that only your screen is not lighting.

If you repair the 24v line and check the 5v feed also going to the ps_on (on) the backlight inverter and you still have no picture...you will need a new inverter.


Hope this helps! Please rate!

Bad power supply or backlight inverter.

If the backlight is not turning on, you should be able to see the lcd image by shining a bright flashlight at the screen.

Backlight inverters are loud, so you can hear them operating (high pitched whine) and if the backlight is coming on, you can see white light leaking around the edge of the screen, and even a little inside the cabinet.

Philips are legendary for having power supplies that fail due to bad capacitors, so that could be the culprit as well.

No picture on LCD tv but sound works!


Yes, i would get it checked first to make sure it is the backlight, if you can see a slight glow around the edges then the backlight is working.
