Question about Philips Magnavox 42MF521D/37 Television

1 Answer

BLUE LINE My magnavox 42' LCD tv was delivered on 9/6/07. The next day it was installed w/the proper HDMI connections using our cable providers HD cable box. Two days later on 9/10 two fine blue/green lines have now appeared down the middle of the screen from top to bottom. I was told by a tech support rep. to unplug tv and cable box for a brief period of time to reset the signal and was told there maybe a sofware problem w/the tv. The two lines also appear when playing dvd,s and when the tv menu screen is on. It appears there maybe a hardware failure somewhere.

Call philips to get this srviced under warranty. this repair might take a few weeks because the failure could essentially be any one of several parts. first thing to try is the ssb, then the logic board and lvds cable. if none of these work then you need a new panel

How can I change the resolution to 720px and above on this television????

What is your signal source and cable type? If your signal is being transmitted by a composite video cable, you need to upgrade the cable to component video or HDMI. (The cable you use depends on the device providing the signal.)

Next you need to set the set top box to an HD signal, if it has that feature. The steps will vary depending on the source. Please add a comment with the source for specific steps. (If you have cable, internet TV or satellite TV, you may need to contact your provider to enable HD programming. Many services charge an extra fee for HD content.)

I hope this helps.

(The source really does matter. My DVD recorder only records SD content. Even though I have the TV set connected to the unit with a component video cable, I don't get HD signal from those recordings or from the Digital-to-Analog OTA converter box that feeds the recorder.)

I just got the Toshib 46rv530u and can't figure out how to get it to change video to 1080p

1080p full hd video can obtain only through hdmi. for that u need a full hd blue ray player or full hd sat receiver . the tv automatically changed to full hd according to the input connecting to it .go to hdmi setting and check whether hdmi connectivity is ON. also check the hdmi setup of ur input device.

How do I connect my hdtv cable box to the tv/monitor. There is no hdmi input on the tv.

Your setup has a TV/Monitor and a audio/video box. The A/V box is connected to the TV and other source inputs connect to the A/V box. Hookup your cable box to the A/V box either using component video (green, blue, red) RCA cables from cable box outputs to the A/V box inputs OR the A/V box also has a DVI/HDMI input jack which may work using a HDMI cable.
Select the proper source.

When i try to play a Blue Ray DVD, the LG LCD tv gets a swath of bright green random pixels across the middle of the screen. The player is connected by an HDMI cable. I have replaced the cable twice,...

Pickled! You did right by checking the cables, the tv inputs and as well the output on the blue ray...even by replacing the blue ray. Which leads to a problem within the tv monitor. I can only guess there is something in the software of the tv that is causing the problem. I can only suggest two options. If can connect the tv to a network via CAT5 cable, you can do a frimware update to the tv. Sort of like a software update. If it is not available, try to swap the HDMI cable for the 5 RCA component video. It will still carry HD signal, just not as crisp as the HDMI. I would be floored if the same thing happened with the component cable.

Connect tv to cable box with hdmi lead

You will need an HDMI to DVI cable which are available in the shops, even ASDA has one but I don't know how good it is. Or you can buy an adapter that will plug into one of the ends of the HDMI cable and then plug into the DVI socket at the back of the TV. The DVI input is video only so you will need audio leads for sound. These will connect from the output of your source, say, blue ray or sky HD (Left and right audio sockets ) to the audio L/R at the back left of the TV (on the block next to the three component video connections and s-video connections)

Can't connect VCR

Connect your 211 to the DVD with component cables, and the DVD to the TV also with component cables. That will enable you to record from the 211 to the DVD, and also watch from the DVD to the TV.
Now, connect the 211 (the 211 will output to both the component and the HDMI at the same time) directly to the TV with your DVI-HDMI cable. Naturally you'll have to complete your connections for sound following the same idea.
Now using the different inputs on your TV, you can source from the 211 or the DVD, and be able to use the DVD to record as well.--------------OR TRY THIS WAY----------DVDVCR needs to use rca (yellow/white/red) plugs as input. Your TV has outputs for that (tv out/ audio out), that will enable your to tape shows from the TV. That's the first connection.
Then connect the green/blue/red outs of the DVD/VCR to the respective in's of the TV. OK, that unit is done.
Now, the 211 to the TV. Using your HDMI to DVI cable (which only provides video as you noted) connect the 211 to the TV.
Now, the audio from the 211 to the TV we can connect.... no way. The answer is that you are going to have to split the red and white plugs from the 211 to the TV and VCR inputs, that's the only way I can see.

HDMI Connection

Yes it does, HDMI can handle more information and provide better picture and sound. Works like this, Cable-OK, Component-Even Better, HDMI and DVI-both Digital and the best sound and video. The only way to get full HD is with HDMI or DVI. Hope this helps

Colours turns blue and green from HD channels

The most likely cause of your problem is the cable box HDMI output. If you have some extra cables, try connecting the TV to the cable box using the component connections. I'll bet your problem will go away. Don't let the cable company lie to you; I work on Sony TV's everyday and see plenty of cable box HDMI issues. Some of my customers have exchanged their boxes 4 or 5 times and still have HDMI issues. Your best bet is to use the component outputs or switch to Dish or Direct TV, as they DON"T have HDMI problems. If this solution works, be sure to rate it. Thanks!

Connection for tv cable to hitachi 42" plasma Tv

there is no cable slot. the monitor is not a receiver. it has no tuner in it. it will need a signal from a tuner box. and that must be fed to the tv with an hdmi cable or a dvid cable for hd to work. see your manual for further information on cables. see your cable supplier for information on hd boxes available in your area. if you do not buy hd service, you will not get an hd signal. so you will see little difference from a non hd device. your dvd player may have hd capabilities, but will also need the same cable to deliver true hd signal.
the good news is that its fixable by using the right equipment.
good luck
