SHARP LC 32D59U LC 42D69U Service Manual free download schematics eeprom...

i had the same problem in a sharp tv 32". on the remote control there was a view mode button, i changed the mode and the pc input label in the left upper corner gone

set comes with at least 90 days labor and one year parts warranty----new or refurbished unit?

I had the same problem. all the service reset would only make the display come on for a few second with no "k" on the screen - only the channel would show up. I purchased a complete set of board for the lcd on ebay, and started swapping them one by one. The inverter boards were the culpret. Tele working 100% since that board swap.

i have the same problem. i just replace the power board because of the "green blinking" light. now, light stays green, picture comes on for a few seconds, then blank....

did you fix your problem.

Off/On The Power switch sudden 4 Straight lines appear on the screen ! what is that & why ?

did you check the sleep mode on the tv?

Go to the roku player settings and change the display type to HDTV and confirm it
This issue will be resolved

1. By View your DVR, Do you mean you can actually see a picture?
2. By "Switch Channels", are these channels being tuned by the TV Tuner?

Your LCD Panel is OK Since you have a Picture (input display in right corner)
If you can see a picture with your DVR, VCR, DVD or any external source then your TVs Video Processing is OK....if not you will probably need to replace the responsible PWB for this function
If you can see a picture with the external sources and only the TV's Tuner is not showing Video, The PWB responsible for Tuning within the TV should be replaced.

Also, if all problems are associated with only the DVR (I assume this is Sat or Cable), then it is most likely that this device is not functioning properly. Possibly lost signal or deauthorized.

You should be watching your dvd's on an input and not on tv analog 3. Every time the tv "senses" a signal change in the audio that screen will pop up. Connect the DVD player to the tv by using either the red, white and yellow (composite) connections or using the green, blue, red, white and red (component). Once you are on an actual input that box will stop popping up.
