After switching TV on, remote doesn't work for first 2 minutes

It need to be service because the problem is from the display panel

Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the site linked here. It has set-up code list & set-up procedure to many popular brand remote controls. Pull up older posts.

There is no harm with it.

If it's the first time using your PS3, use the composite cables that came with it. Turn on the PS3 go to video settings and switch the input to HDMI. After you've switched to HDMI, turn the PS3 off and connect your HDMI cable, go back to video settings and change the resolution to 1080p. If this isn't the first time you've used HDMI for your PS3, make sure your T.V. is on the correct input. If the T.V. is on the correct input, try switching the HDMI cable to a different input. If that doesn't work try using a different HDMI cable, testing different HDMI connections if you're still getting the black screen. If none of those work then it's probably a problem with the PS3, but just to make sure try plugging something else with HDMI to see if that works. If another HDMI device works, then it's your PS3, if it doesn't then it could be a problem with your HDMI connections on the T.V.

this is due to surface mount capacitors going faulty on the side buttons panel. You can simply disconnect the cable from this board and use you remote to control the channels and volume. if you want it fixed you will have to replace the side button control panel which is a cheap part.

heating up issue, try unplugging it and if you can clean the dust from within the unit. Try reversing the vacuum and blowing excess dust out.

Picture is not centered on monitor leaving a 2 1/2 inch; black border on Philips LCD
By dmorrow54 on Nov 13, 2007
Again, nothing in manual for Philips LCD will correct the fact that the picture in HD-D mode will not center. The picture runs off the monitor on the left (facing the monitor) with a 2 1/2" black border on the right (facing the monitor). Using the format button on the remote of directional arrows will not correct the issue. The wide-screen/ full-screen function with format does nothing. Moving into TV mode, the format function works to display screen in several ways 4:3, 19:2, super-zoom, wide-screen, full-screen. Help, please. posted 3 years ago

I have a Philips 30 inch LCD and solved the problem by using the circular arrow button on the TV remote. Pointing it at the TV and clicking "right" (3 o'clock on the button), the picture moved right. Same thing on for "left". Worked for me.

   WOW! It works!! The picture on my Magnavox (aka Philips) 37MF321D had shifted to the right. I figured I had a big repair bill coming up soon. But hey! Just used the TV remote as described by "Guest', and re-centered the picture to the left. Wallah! Thanks ""Guest" whomever you are! Reply

My TV remote has a slide-switch at the side to switch between the TV, DVD or VCR. I don't know if yours has one, if so, switch it to TV. It also has a button to switch between Analogue, Digital and External, so make sure if you have a button like this that it's switched to the right input.

Turning the power off shouldn't have caused the problem.

Make sure the TV is set to the correct HDMI (1 or 2) by pressing AV on the remote and moving up and down the list.

Check the laptop is set to output through the HDMI socket.

Right click on the desktop -----> properties ----> settings

Actual options depend on your graphics card.
