Question about Philips 27PT5441 27" TV

1 Answer

TV was Fine last night, this morning there is picture, but no sound

I have a Philips TV that is about 4 years old. Everything was fine with it last night. Today, I was cleaning and used the vaccum dusting attachment to clean the back of the tv (it was not turned on) and behind the entertainment center. After I was finished cleaning, when I turned the tv on, there was a picture, but no sound at all. The only difference that I noticed, besides the silence, is that "mono" shows on the screen everytime I change the channel. The closed captions work and I was reading in another person's post that that could mean that mute is on somehow. I muted and unmuted with the remote, but nothing changed. I plugged headphones into the headphone jack and could hear background static-y noise but no true sound. I tried playing a DVD to see if I could for some reason get sound like that, but when I put it on the channel for the DVD player, all I get is a black screen instead of the menu screen coming up. Any advice or suggestions you can give to help locate and fix this problem will be greatly appreciated. Thanks.

Re: TV was Fine last night, this morning there is...

Since the you were vacuuming behind the set before this happened, I'm going to assume that you unplugged an input. Check the wiring, not just on the back of the set, but, on the back of the peripherals (DVD, Satelite, cable box, etc.) If wires are connected, then, take a component, such as a VCR or cable box and hook it up to the RF connector (AKA the cable connector) and run it on channel 3 or 4. If you have sound, then, you have a configuration problem and need to rewire your set. Hope this helps.

My Philips TV will not turn on

More than likely it's activating the protection circuitry. Most of the time televisions won't give you a sign of trouble until something actually breaks. One day they work and the next they might not. There could be a problem in the power supply or the scan section which are both internal that would inhibit operation to prevent your set from overheating and causing a problem external to the TV like a fire. If your set is over 10 years old, replace it. If it's quite new but out of warranty then get an estimate at a reliable electronics repair store.

Picture is gone! :*(

the picture tube (what makes the TV picture work) has blown out. Just call you nearest tv reapair shop and purchase a new one. (these are kind of expensive!)

(Also, if it's fifteen years old, i think it's time to get a new T.V. hint. hint.)

No picture, sound ok

Rca has been known to have bad solder joints in the deflection circuits. Usually around the flyback and transformers.. check it over real good. Just be careful as you can still get shocked after the powers removed the capacitors and picture tube will hold a charge in them.

shannonlamb- check the back of your set where the cable ect. hook up, there may be a button on the back for speaker on/off.If not then check the menu to see if there is speaker on/off in menu make sure it is on.The last is the old tap test, just tap the back and sides,if you get sound at all it is internal cold solder joints.Let me know ----- cooltek Feb.15/08

No Sound on TV

In the menu option, see and make sure that the speakers are turned on and that the Mute is off. Also if all that is good then unplug the set for a good 24 hours. If that does not help, and your not experienced at repairing solid state electronics, please seek out a local repair person to trouble shoot this for you.
