Question about Philips 27PT543S 27" TV

Open Question

TV loses picture after 2 o3 seconds. TV is on but picture black

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

Hello mikekahan,

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,

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:
062596 Menu

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):
OP1: 065
OP2: 215
OP3: 065
OP4: 162
OP5: 204
OP6: 201
OP7: 000

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.

Model no. dtq2605fc how do we hook up a dvd player to this?


There are several ways to hook up a DVD player to a TV.

The simplest method, which works with any TV, is to use the DVD player's RF (radio frequency) output on channel 3 or 4, connect the output cable to the TV's antenna jack, and put the TV on the appropriate channel. There are two problems with this method, though. First, I'm not aware of any new players that have RF output these days. The manufacturers don't include it, figuring you'll be using the direct audio and video outputs. So if you're trying to connect a new player, you likely don't have this option. Second, if the player does have RF out, it's usually not stereo sound and the picture quality can suffer.

If the set has AV input jacks available, you would use those and select the AV input from the remote control or front panel. There are some possible problems with this method too. The biggest one is that if you've lost or thrown away the original remote, you might not be able to select the AV input. (Don't laugh, many people don't realize they should keep the original remote even if they never use it.) And on TV sets with only mono sound, you need a Y-adapter cable to combine the right and left audio outputs into one channel, so you lose any stereo effects.

The last way is for TVs without an AV input and DVD players without RF output. You use an RF converter (also called an RF modulator), which takes the audio and video signals from the player and makes a channel 3 or 4 signal you can tune in as I described earlier. RF converters are available at Radio Shack stores, most TV retailers and from many sources online. They're easy to connect, but you'll need an AC outlet nearby since they need power.

One of these methods will work for you, and you'll be watching DVDs soon. Thanks for using Fixya!

My screen is blue and it wont let me see anything


Hello
Your TV is not getting any signal at all to process, or the tuner inside your TV is faulty. Blue back screen comes, when there is no signal to any of its input or faulty tuner. Just connect the tV with any other video source, like VCR or DVD , connected to its AV terminals and set the tV to take input AV, and check whether picutre comes in or not. If picture comes with AV connection, make sure that your tVs tuner is faulty and should be replaced. If no picutre comes with AV connections too, the Chroma Ic insie your TV is faulty, and should be replaced. OK.

I have a problem conecting my sharp 25h-M60 with my DVD plyer.I have found solution on Fixya. They said I have to use VCR. My question is: What does VCR mean?


If your TV does not have AV inputs (RCA jacks for video and audio), you can't plug the DVD player directly in to the set. One solution is to connect the DVD player to a video cassette recorder (VCR) using the "line in" jacks on the VCR, then using the channel 3 or 4 output from the VCR to the TV. This solution may not work with discs that have copy protection, though, and will give you an unwatchable picture.

For sets with no AV input, you need an RF converter. This is a device that takes the video and audio signals from a DVD player or other device and makes a channel 3 or 4 TV signal to the TV's antenna connector. Converters are available at most retailers where you can buy televisions, as well as online.

I cant find the av jacks to hook up my dvd player


This model doesn't have any A/V jacks. Many low-end RCA models didn't include any special features. They can only pick up signals over the antenna input. What you'll need to connect your DVD player is an RF converter, which takes the audio and video signals from the player and turns them into a channel 3 or 4 TV signal that the set can pick up.

RF converters aren't hard to find. Radio Shack, Sears and Wal-Mart all say they sell them, and you can certainly find them online. Hooking one up is just a matter of connecting the necessary cable to the player and TV, connecting the converter power and setting the output channel. Then put the TV on that channel and you're set. Unfortunately, this will give you lower picture and sound quality than you get from a TV that allows direct A/V inputs, but it's the only option.

TV screen goes black but tv is on. But will stay on sometimes.


i have a 2000ish 32 inch trinitron Wega and i have had the EXACT same problems as you have, except mine was blacking out more and more frequently, but yes if u changes the channel or hit return onto the same channel you're watchin the picture wil come back, but not very long, about the longest it'll show a steady picture is 1/2 hr, but it's usualy going black within every 10-15 mins or so.

I took it to a Sony approved/recommened repair shop and aftet having a look i was told it would cost $200 cd including taxes to replace a 'vacuum tube' or something like that, i wish i could be more specific anout the part. I'm still considering whether or not to go through with the repair. I might just buy a working/used newer Tube Flascreen with HD for another couple hundred dollars. If there was a newer 2003+ 32 or 36" Sony that has a good track record I would love to hear suggestions. I don' trust flat panels, way too mny horror stories, and for every 1 i hear about there's probably 10-20 more.I'll give them another 5 years or so to get their acts together.

On the other had, if i do decide to get my 32" wega fixed i will post the results and the exact pt numbers of the pts used i the repair. Your problem is exactly the same as mine, to the letter. I'm a mechanic by trade, but i have a good feeling they're not going to give me correct pt # until i have payed them to fix it. Or else i'd order the part and install it myself.

Good Luck,
Aaron

Prima HDTV has a black screen on TV, but works fine while Playing DVD


try turning the channel up or down with the tv remote to input 1 or 2 depending on which one is being used for the dvd player. tv should use input 1. dvd should be on input 2.
when turning the channel set it to show the dvd screen, then go up 1. if it doesn't show, return and go down 1.

Hello,
I just wanted to suggest some things for you to try, if you have not done them already. Try hooking up a known good signal, such as the main input cable from your cable or dish, hook it straight to your tv, and see if you can change channels, and get a picture on low band...2 thru 6, and then if not, how about any picture above channel 6, if you get picture on 2 thru 13 now, it could be whatever you have hooked in between the input cable and the tv...be sure you have the tv on the right channel for your receiver, usually 3 or 4, or if you are using another type of video input cable, make sure you have tv on the right input for that cable and that cable is good...check the in and out of your component unit, for correct cable hookup as well as your cables, in reference to using RCA video and audio left and right in and out...a lot of sets and vcr's will go to a blue screen if they lose signal to them....I hope this helps you out some.If you cannot get a picture from hooking your signal straight to your tv, it could be the tuner got a spike from a thunderstorm, or has lost the B Plus source for the tuner circuit. Be sure that it is not selected for an input signal,other than the cable or antenna mode, the onscreen text should verify this, if you can change channels with or without getting video...a picture....Good luck with it. T.

No Signal through on my main TV input.


This may be the tuner or IF module that is failing. It may also be a voltage supply fault to these modules. It is impossible to accurately speculate without actualy troubleshooting the set.
