Tv has started a sporadic no signal during turn on and when already on. sometimes fine then jumps to dark screen and displays no signal . and sometimes plays fine till i turn off. does not show the white static screen when there is actually is no signal. and have checked to make sure it was not at the source. any thoughts on which part i might need? thanks

Depends on what you are doing. Sometimes the "full screen" is dependent on the signal coming into the TV from a cable box. Check the setup or menu function on both the TV and whatever input signal you are using. You didn't say what TV and what source i.e. cable supplier, antenna etc. Remember that an HD tv doesn't always display a non-HD picture in full screen.
The remote control is an acess to the TV device for example only from a distance. A remote controll for functionality would require to insert batteries a power source making possible communiction with devices requiring reception transmittion of signals. The remote is handheld pointed to the direction of TV requiring signal before button pressed woudl achieve response. a common button to start the remote control experience is pressing on the power button, that displays a signal on the TV. The TV should momentarily produce a sound and lighting effect,, and displaying on the dark screen a light blue screen. The initial signal response from remote control to TV indicates devices are functioning as required. Additional buttons on the remote controll could perform functions of several available.
The remote control has master button, menu on which every additional function is deriveable. Once the menu button is pressed with remote pointed in the direction of TV, should dicplay a list of options on the blue screen already established by power button. Every additional remote control device functionality is achievable by only after the first two buttons have been powered and pressed to display option results on a screen of TV. The remote controll buttons remaining perform complementary functionalities. For example, the arrow keys on remote control make movement of the options displayed on the screen, where a comfrimation button or identified as select allows to confirm remote functions displayed on the screen. A remote control could have several functionalities only accessible once made to display in screen. The three most common buttons on a remote control are First power button that powers on the TV, menu button that displays a list of functionalities on the powered on bl;ank blue screen, and using the arrow buttons on the remote would moves an indicator arround the screen area options. The selection button makes confrimation of the option.
Check to see what input setting the tv is on. It could still be looking for a signal from the pc input connection and no pc is hooked up thus getting no signal. Have the device you are trying to display on the tv connected and turned on and cycle through the inputs on the tv until you get a signal.
Have you moved the unit recently? If so you may have dislodged the projection unit and have something blocking the left side. Another possiblility would be a bad video card which is not turning on soon enough during the scan. You also may want to check the display format to make sure it is in the proper format for the signal you want to display. Let me know how this works out.
I think the problem lies with what input you have selected on your tv. On your (tv) remote control there should be either a circle or square with an arrow on through it. With your pvr already switched on, turn your tv off then on again. When it says no signal, press the button on your tv remote I've described until you see a picture.
I'm working on one now. So far, I've found two capacitors on the power supply board bad, both 1000uf/16V 105 degree caps location EC9 area. Still have mild interference on the screen which seems to change with the type of video being displayed.. Will look for C301 next, is it on the signal board?
Er00 - The software that was available for upgrading was of an older or of the same version as the one already in the digital-box.
Er01, Er02 -The upgrade failed. Some information was missed out.
Er03 - The internal memory is not large enough to receive the upgrade.
Er04 - The signal was disturbed during the upgrade.
Er05 - Wrong type of data was received during upgrade.
Er06 - Not used.
Er07 - Access problem in back-up memory (EEPROM).
Er08 - Access problem in video memory.
Er09 - Can not find any data to do an upgrade.
Er10 - Poor or no cable-TV signal.
Er11,12 - Not used.
Er13 - Unauthorised data signals received by the digital-box.
Er14 - Faulty data signals received by the digital-box.
Pb01 - A problem in the ROM memory is detected.
Pb02 - Memory size is too small.
Pb03 - A problem occurred during start up (initialisation problem).
Pb04 - Internal communication failure.
PbF9 - Hardware error identified during start-up
From elsewhere on the web:
1. Turn off the unit for 15 minutes to cause a full reset. 2. Turn on the PVR with everything attached except the antenna input. 3. You will get an Er09 on the display. On my PVR there was no output on the TV screen whatsoever (totally black screen). 4. Press 'OK' on the remote (confusing as there is no clue that this is what you should be doing, though Sagem support thought that the PVR should prompt you. 5. The box reboots in standby mode."
I also see some mention that if the above procedure doesn't work, try pressing "Menu" twice to see if that clears error 09.
This sounds like bad inverter board.
Every time LCD goes from Standby to ON state - Inverter Board resets it’s self for approx. ~1 sec, during which time you should see blue screen.
Problem is that board detects problem with voltage/current on one of the seven transformers and shuts down automatically...
As to the costs:
- BestBuy repair service approx.. $600.00
- Buy new Inverter Board & repair LCD your self approx. $200.00
- Another option is to repair Inverter Board, but parts are sometimes hard to get...
Now for the DON"T TRY THIS AT HOME or AT YOUR OWN RISK solution:
-The cheapest method is to bypass protection circuit, by transferring good signal from working transformer (using 10nF/250V capacitor) to detection circuit at the faulty transformer.
Then watch movies on your LCD unlit BAD transformer totally BURNS-OUT.
This will be obvious by dark stripe about 1"-2" tall across your display.
Hopefully the only damage will be to the transformer and not CCFL (light behind your LCD), but when you are faced with a choice of using it for a while longer or throwing your LCD to garbage right now... to me this choice was simple.
