SOURCE: Can not access menu or input functions

Hi rduncan27,
I will be happy to help. 88% of LCD tv problems are with the backlight, the symptoms you described indicate a probable inverter malfunction. Lets do a simple test to check the functionality.

  1. Get the tv to a point that it is producing sound.
  2. Take a flashlight and shine it on the screen.
  3. Look very closely for a dark video image.
Let me know your findings and we can proceed from there.

SOURCE: DELL LCD TV locked up w/screen message "main menu locked"

without a remote and disabled keypad keys, the only other option, is to open the unit up a physically RESET the TV. remove the cables from the power board. i believe it has a phillips head screw. careful when you separate the rear cover from the front cover. there is a board screwed in the lower right corner, there is a connecter and a ground cable screwed to the rear cover. take your time prying on the rear cover. once you separated the two pieces, look for the light yellow board with your AC power source. Unplug it for 30 minutes and repeat the process. while your at it, also look down to the lower left side of the monitor. u should be able to see the keypad. press each button, while pressing, look to see if the button is pressing against the circuit board. it may be loose, try this test, u just may be able to fix your keyboard as well. hope this works out.

Is this tv a smart tv?


Good morning Shelly.
My Samsung smart TVs has a remote like the one in the picture.
In the middle, I hope you can see a multicoloured button that is to put on the smart function. It is best to go to menu on the remote, open Support and scroll down to Contact Samsung, go all the way down, there you see the model and make. You can also visit

No picture, just sound on Etec Flat Panel 40A99


Video circuit is separate from the Audio circuit. The main controller may switch to Audio, but if the unit is damaged from a power outage; part of the circuit board may not function. Needs professional servicing.

Original remote lost. have universal remote. cannot program TV


On the right hand side of this television there are panel buttons. It appears that your son in law knocked the tv out of the correct input. Press the input button in order to cycle through the 5 inputs. Typically pressing the input button on the side panel of a television and pressing it again and again and again will make it change inputs. Universally the buttons on the tv panel function as follows: Channel up moves the cursor up. Channel down moves the cursor down. Volume + moves the cursor right. Volume - moves the cursor left.
Hope this helps

Have power (backlite) but no screen (menu or any control from side buttons) will not turn off.


Try disconnecting the tv button pcb interface connection to the mai board once switched on and try using your remote control functions. If there is still no menu or functions, this cancels out the buttons pcb, and the fault is the main pcb.The voltages are ok which you mentioned..12v..5v and the 24v invertor feed voltage so it will be the main pcb..If you had sound and remote functions i would have said it may be the Tcon as well as the main pcb.
If the remote works ok with tv buttons pcb disconnected, then the problem is the buttons pcb.However, you have no picture..i presume nothing at all including 'no signal message or menu screen'. Therefore, with no bulging caps and correct votages to the main pcb, you will be right to change the main pcb.
PLEASE DO NOT CARRY OUT ANY ELECTRICAL REPAIRS IF YOU ARE NOT COMPETENT TO DO SO..ALL MAINS PARTS ARE DANGEROUS..GET A QUALIFIED TV ENGINEER TO CARRY OUT ANY REPAIRS IF THIS IS THE CASE.

JVC AV-27D500 27" TV


The closed caption or PIP functions in mostly all sets are only acessable trhough the menu.. You need the original remote to do this. If you dont have one go to http://www.remotes.com or call 1-800-remotes for inexpensive exact replacement remote controls. If you do have the original remote and can acesess the menu but the features are not there then theres a problem with the sets built in firmware and the only way to fix this would be to replace the sets microprocessor IC. Good Luck
