By tries to come on, do you mean that the picture flickers? I have seen this before and most of the times it faulty inverter voltage from the power supply.

    Its very inexpensive. There are two of them in your set master and slave inverter. The parts can be obtained from the link below. There are several alternative parts so I suggest you have look at the labels on those in your set and buy the ones that match that part number.

This is a fairly classic switchmode power supply problem. The protection circuitry inside the SMPSU, has sensed a severe potential problem, and is attempting the shutting of the set, down to avoid a fire, explosion, or both.
This set had developed a problem, that is so severe that the set must be shut down, (This set should be removed from the Power),
What is happening is the internal "Fault" that is causing the Protection Circuitry , to detect the problem and attempt to shut down the set, keeps restarting the set, because as soon as it shuts down, the "Faulty" component(s) cool down?, and the "Fault" ostensibly "Clears" so the PSU starts up again, only for the component(s) to heat up, whatever, again and fail, so it shuts down, and if left unattended, this would continue on until the part eventually failed. As related this is called a "Hic-upping Power Supply". Any fault that involves the power supply is usually quite serious, and needs a professional, usually, unless one is familiar with servicing current day, televisions.
And in my professional recommendation, you should get a "Quote" for repair, from, an, Approved Service Center. Now, this point is very important for a good result, Always contact, their "Local" or a, "Head Office" Philips in your case. Ask them, for a referral to an authorised servicing center, where you ask for a "Quote". Now, when you get the information you want, then you can decide as to repair of replacement.
The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand, also sometimes, there has been a service bulletin in issued and the repair may be subsided or even free. There are many, many, many reasons that display this symptom, one must work through the troubleshooting steps to isolate and identify, the Cause and repair that and any damage done.

Sound no picture


Your video cable is not plugged into the matching input to your audio. (ex. audio is on input 1 and your video is on input 2) Once they are matched make sure you television input is matched to where you have them plugged in.

Our tv when itis on for a while some times the picture freezes an then goes blank an a loud hissing an squeech sound we have to unplug it to turn it off.


Hissing sound normally from Power Supply unit(PSU), usually from Transfomers in the PSU. Usually caused by bad capacitors. Try this capacitor replacement kit, on ebay only $15. http://www.ebay.com/itm/Repair-Kit-RCA-L32WD22-LCD-TV-Capacitors-/230637983468?pt=LH_DefaultDomain_0&hash=item35b31856ec

Could not find any PSU board available at the moment, but have tried that kit and it works.

Rca tv/dvd combo L32HD32D powers on and for 2 seconds shows, Please Wait, on the screen then goes black. What do i do?


After the screen goes black, do you still have sound or you have none but a blank screen? If you have no picture and sound does the power LED in front of the tv indicate that the set is on, or does it go into standby? Please provide this info so that I can help you with your problem.
