I Have a Hitachi42V525 High Definition TV; rear projection; it's only a few months old; for the past week or so; when you power up; the blue light comes on and blinks - which is usual; the red lights beside come off and on; sometimes stay on - but we get no picture; and after a few tries sometimes get sound. Sometimes if we leave it for a bit the picture comes on? Help
I changed the inputs into another port - ie. instead of being in video 1 it's in video 4 now... I don't have as good a picture but it does come on; I'm wondering if my system took some kind of volt or fluctuation and damaged th eone set of inputs?

Below are some troubleshooting tips for a TV that has a fuzzy or blurry picture;
If your Plasma or LCD TV picture is blurry or fuzzy there are several things that may be causing the problem. It's worth running through the following list before seeking service. You may find yourself saving the full cost of a TV repair.
Make sure you are using the appropriate cable box for your TV. If you have a high-definition TV you should also be using a high-def channel box from your cable provider. Watching standard definition channels on a high-def TV can make the picture look distorted and fuzzy.
Not all cable channels are broadcast in high-definition. When you stretch a standard definition picture to fill the full frame of your wide-screen TV it may look distorted. You can try changing your TV display settings to show standard-def channels at their native resolution. This will create black or gray bands on either side of your picture.
Ideally all of your video components will be connected to your TV with HDMI cables. Your next best option will be component video cables. If your cable box does not have HDMI capabilities, contact your cable company about upgrading your box to one that does include HDMI.
Make sure there is no glare on your TV from a window or other strong light source. This can significantly degrade the quality of the image you are watching.
If your TV has digital noise reduction, try turning that feature on.
You can adjust your TV's sharpness and picture modes to see if that improves picture quality.
Try plugging the power cord into a different electrical outlet and/or surge protector. You may be receiving electrical interference through your power cord.
Trying moving any nearby electrical devices away from the TV. They may be creating interference that can degrade the picture quality.
Let me know if the above helps or not, so that I can direct you further on what do next.....
You do not need a high def receiver, your unit has an ATSC tuner which is the same thing. You do need to hook it up to a high definition signal. You mentioned that you have satellite. Call your supplier and order the high definition channels if you do not already have them on the downlink. They should be able to tell you if you have them or not. They should also be able to tell you which channels they are (normally the higher ones). Once you have a high definition feed you will have the best picture you are going to get with todays technology.
Thanks for using FixYa and for the great rating. Please consider a testimonial.
Is this hooked to a high definition dish network? If so there is a format button on the remote to change the picture size. As far as changing it to 1080 it will only broadcast in what it sees if it is not in high def it can't broadcast in hi def.
On any High Def TV, the reciever you need for this set, which does not have a HD receiver in it, is half the equation. Most HD channels have some HD content mixed with SD content on the same channel. SD content on HD signal from cable or satellite tends to be slightly blocky due to the native signal resolution and the resolution of HD (1080i/p or 720i/p).
