Philips 32 LCD TV 32PF9541 Black Screen

Hi,

I bought a Philips LCD TV model 32PF9541 4 months ago. About 4 weeks ago the screen started to go black while watching the tv. The sound stays perfect and I can still change the channel and hear the channel change but the picture stays black. I tried it with a DVD and had the same issue so it's not my satellite connection. I also unconnected and reconnected all cables a number of times but this did not help.
On some occasions it does work. If you power on and off the TV a couple of times it usually fixes itself but it is happening more often now and on a bad night it will go black every 30 mins. I have taken it back to the shop and they are being particularly unhelpful. They have said they can not replicate the fault in the shop but I am very nervous about taking it back as I don't want the warranty to run out.
I would be really grateful if someone could let me know if this sounds like a technical fault with the TV or something I have done as although I tried a number of things to fix it, the shop are making me doubt the problem.

Thank you,
Paula I have the same problem Paula described with a Sharp Aquos 32 when I first turn the tv on a clear picture will be displayed then within 60 seconds or so it goes black with sound being fine. I invested almost 2k into this tv and the problem did present until 14 months (2 month past the warranty). Someone told me it would cost about 650.00 dollars to get fixed.

    Same problem on Philips 32 CRT (vintage 2004). Display goes black every 30 minutes or so when watching digital broadcasts through converter box. Analog and 'over the air' broadcasts do not elicit same symptoms. The only workaround appears to be turn set on/off which obviously isn't the best and will eventually cause premature failure of some component.

    Had the same problem. If you get real close to the screen when it appears black and see a faint picture on the front face then the backscreen lighting is shot. My was under warrantee so Sharp replaced it. It is a plug in module.

    Hello there,
    it sems that i´m having the same problem, i have the same model as you, there´s one thing that will bring the tv on again, is upgrading the firmware, but after a few days the issue will come up again.
    I´m considering contacting the retailer for solution, or perhaps maybe better, contacting philips in my country.
    By the way i´m from portugal.
    I have even tried entering the service menu, but still it happens the same, and the error report menu doesn´t show anything. I don´t know exactly what´s happening, but it´s happening more often.

Sounds like a temperature problem if it takes a while for the problem to happen there are several things u can try and figure it out yourself. 1. Remove the back cover of the tv and turn the tv on. 2. use a hair dryer and apply heat to various boards of the lcd (inverters, power supply and scaler) while applying heat to see what board reacts and makes the tv go dark. More than likely its a defective LCD panel and its just as easy to send it back and get a replacement TV.

I have sound but no picture. 42" plasma. i bought 4 years ago. last week the botom half of the screen started flashing back and forth between the picture and all black, but we just came home and now it is...


Sounds like you need a lower Y-DRV/BUFFER board (996500032640) and a Y-SUS board (996500032643). Part numbers listed are for models which use a Samsung Panel.

No data is sent to the screen


When the screen goes completely black, shine a very bright flashlight closely at the screen. If you can see the image, then the most likely problem is that the backlight inverter has failed.

The inverter is a circuit board that works like a flourescent light ballast. If the inverter fails, there is no backlight, and the screen is black.

Since the invertor is a high-voltage component, I would also listen for any unusual sounds associated with the failure: e.g. buzzing, whistling, popping.

To rule out some sort of connection failure, see if you can recreate the failure mode when using the TVs internal setup menu. The setup menu does not rely on any external inputs....of course neither does the volume control or channel indicator on the screen.

Sharp aquos hdtv has sound but shows a white screen


yes and no. That particular tv you have is done for, but if you just purchased it 6 months ago, you are still within you 1 year warranty with sharp. they will ask you to take it to a authorized service center and you need to follow through with the process. about a week or 2 will pass and the service center will deem the unit unrepairable and sharp will replace it if they cant solve the problem. give em call..good luck 2u
