Question about Philips 27PT543S 27" TV
If you turn tv on and set input to a AV input with no signal like a DVD input with the DVD's power turned off. It will often stay on. Sometimes the TV will stay on when set to a station after the tv has been on for some time but set to a open AV position. It seems to shut the video off when the tv is turned on and set to a Station channel other than a open Video input. Sometimes it will stay for some time if you turn the tv on ,leave on an open AV input position for 10 or so minutes. Then turn to an AV input with a DVD player attached and on then it will play the Dvd sometime for the whole DVD.

Check your input cabling and connectors and make sure you have a good input signal. Put another tv on this same input cable and see what happens. Keever

Hi , Most older Television allow you to access the AV input line by selection a high channel. That is a normal function on your television. What are you trying to do since you do not have the remote control? Thanks, Mike

OK you are not going to like this but here we go any way. First of all I need to explain how your channels are created.
When the RF signals come into the headend of the Down converters they are separated into pre channelized designations DC (Down Converter) 4 Stream 1 (DC 4-1, DC 4-2...) now once this is done the down converter signal is fed into a channel processor which takes the incoming signal from the Down Converter remodulates it and puts it on an assigned channel 4-1 could become channel 4, 4-2 could become channel 5 and so on. Once this is done you end up with your regular channel line up for analog channels, now for digital its a little different you have IRDs (Integrated Receiver Decoders) which take the off air or satellite Digital RF signals and convert them into MPEG Streams which is the fed into what is called a SEM (Motorola Architecture) Stream Encryption Module which assigns numeric designations to the MPEG streams and then converts the MPEG streams back into RF. Now at this point we have analog and digital signals what then has to happen is the the analog signals must be turned into MPEG streams to go through the system so what happens is from the channel processor the analog signal is put into a SE (Stream encryptor) Like the SE1010. This takes the analog stream and turns it into am MPEG stream and feeds it into the SEM also and the SEM assigns a numeric designation just like the digital signal and this can sometime follow the same numeric designations as was obtained from the Down Converter, So what you end up with is analog and digital signals having the 4-1, 4-2, 5-1, 5-2, ..... format. This is where other equipment comes into play These designations are then kept in a database and are matched to their proper channels by use of the DAC and RADD along with an IPG server. These allow the SEM to assign true channel designations to the converted channels, now the SEM DAC, and RADD talks to your STB, this is way the channels are correct because the SEM and the DAC/RADD are matching what is on the IPG (Interactive Program Guide). When you remove your cable box the tuner in your TV does not know how to deal with the DAC, RADD and IPG signals so it only displays the RF information which is the 4-1, 4-2, 5-1, 5-2 data.
I hope this helps,

You either have a cold solder joint in your horizontal deflection circuits or your or in your horizontal output circuit. please be careful due to the fly-back transformer still holds power even unplugged until you discharge it.( ground it out). Hope this helps.

This worked for my 20" Philips Magnavox 20MT4405/17 TV, it might work for you as well. DISCLAIMER: This is just a solution that I pieced together information from various internet sources, as I could not find a free copy of the service manual to verify this. Furthermore, I am not a technician of any sort.
Enter your TV's service menu by pressing this sequence of buttons on your remote while the TV is on:
Use the arrows on your remote to scroll down to "Options", push the right arrow to enter options.
Change the 7 options parameters in order to (write down the original values in case this does not solve):
You need to enter all 3 digits for every number, even if there are zeroes. You use the numbers on the remote to do this.
Turn the TV off with the built in power button.
Unplug the TV for 10 seconds.
Plug the TV back in, turn it back on.
If this does not solve your problem, reset the values of the options in the service menu to the values you wrote down earlier because you have a different problem than what this fix works for.
