Loss of selected video input when power is turned off with remote
I have a Hitachi plasma tv model 42hdf52 and was purchased new in august of 2005. If I turn the tv off with the remote or use the tv's on/off button on the front panel and I leave the tv off for a few minutes and then turn it back on it will lose its selected input and the monitor will go to sleep. Each time i turn the tv back on I must also select the proper input to watch the only source i have connected which is a directv receiver that is never turned off.....it stays on. I do not have this problem if i only turn the tv off for a minute or two. I have the unit connected with the blue,red,green seperate video cables. Seems like there would be a default input you could select................right now it always defaults to the worst possible......the composite input!!! This sucks! I have a macro remote but it cannot be 100% effective because if the tv is only off for a minute.......the macro sends the wrong number of commands to make my tv land on the proper input!!! please help if you can

Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Please check the INPUT of your TV by pressing INPUT, SOURCE or TV/VIDEO on your TV remote. Once you press one of those ( that was on your TV remote ) you should have INPUT lists on your TV screen. All you have to do is select each one on the list until you get a picture ( normally input is TV ). Hope it helps.
Hello It will be difficult to match any other universal remote with this model Hitachi set. You have to get the original remote control to select all the functions with this TV. If your original remote control doesn't work at all, just buy a new one. You can get it from the authorised service center for Hitachi at your town. OK.
If you have tried autoprogramming and have found nothing it may be a bad tuner. Is your VCR is hooked up via coax or into a video input? If it is hooked up via video and is working but the coax connection direct isnt it will be a bad TV tuner. Easiest cheapest fix is to use you VCR to change channels or get a Digital Cable Terminal from you cable provider and hook it into video or compnent.
First, is the DVD player output (Video out, audio out) connected to the TV input?
Have you used the Yellow cable from DVD video out to the TV video in? Mixing the audio and video cables will result in no signal.
Have you selected the proper input with your TV remote control. Most plasmas accept a variety of input signals; you must select the right one.
I deal with a number of these issues. Usually the connections are made improperly or the correct input source is not selected with the TV remote.
Put a DVD in the player and press play. Be sure you have made the proper connection from DVD player video/audio out into an auxiliary or video input on the TV. These could be labeled Line 1 or Line 2. With the DVD playing, run through the input options on your remote control. The button might be marked source, video or input. The screen should display your choices i.e. video 1, video 2, etc. When you see your DVD program, you've got the right combination.
