Infocus tv will not turn on power channel volume and menu buttons are lit up blue and stay on


First thing to do is unplug set for a while and plug back to see if issue cures with a reboot.

General info:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

Can't turn on or off with with remote. Turn on with front panel power switch and the Volume goes to max and Volume indicator displays constantly. Any ideas?


You may have a bad switch on the front control keyboard:
HAVE THE SET UNPLUGGED

1. Remove front speaker grill (it pulls off).

2. Remove inspection plate behind it.

3. Note the bundle of wires coming down from front keyboard, follow them inside and to the right where you will find 2 plugs in line, unplug both plugs: they are marked with letters and different so you cannot plug them back wrong.

4. With keyboard now unplugged try to operate the set with the remote (remote receiver is behind front screen).

5. If set now operates with keyboard out of circuit, you have two choices:
a) operate set with keyboard disconnected
b) remove entire screen unit to get at circuit board behind the buttons on front of set.

I have seen a lot of these sets with defective micro switches on that keyboard.

Before you rate this information let me know what you find and if you have any questions.

Cleaning a projection tv screen protector


Most of the time there are screws comming in from the back holding the front piece to the back with the screen inbetween. They are probably something you will need a small socket or a allen key set for. Good luck.

My tv has no volume,i checked every cable connection and it all fine.I know my speakers are fine in the tv everything was fine until a button was pressed on one of the remotes the tv or the direct tv...


Remove all batteries from your remotes. Unplug the unit for several minutes. Plug unit in and use the controls on the set to turn it on and adjust the volume. This will eliminate the remotes. They could have a button stuck. If this does not work you may have a legitimate problem and need a tech.

I was tring to remove the concave off my screen and came across a setting where you can make the picture larger or smaller. On the TV, not the remote, press and hold the menu button, press and release the power button, press and release the volume up button and release the menu button. P0 and V0 will be displayed on the screen press the volume up button until the V0 is V76. Press the channel up button until P0 is P11 and press the volume up/down button to make the picture larger/smaller. If you need to center the picture press the channel down button until P11 is P10 and press the volume up/down button to center your picture. I hope this helps

Picture too large for screen


If the television is connected to a cable box such as Time Warner's HD box, the picture mode can be changed by pressing the '#' on the cable box's remote keypad (where the channel numbers are). This cycles the picture between zoom, normal, and stretch which could be cause of your problem.

Panasonic 50" LCD TV PT-50LC13


I did the following 'press and hold both the "VOLUME Down" button on the TV itself and the TV/VIDEO key on the remote control simultaneously for about 7 seconds (they say over 5 seconds in the manual)"

Will in the service screen I selected the number of hours of the lamp with the down arrows and the action buttons. Then I simply pressed and held the "down volume button" on the remote until the number of hours was 0. Then I turned the TV off, then back on and the message was gone. This worked for me.
