Try unplugging the set and a box if connected to it for a while, plug both back up allowing possible reboot as either could cause this problem.

    I tried rebooting and that didn't work, so, whomever I spoke with on the phone recommeded I call a tv repairman. Hell, if that's what my $28 paid for I'm in the wrong business.

SOURCE: 'F' displaying on screen and remote not responding.

Excavated with Google from Philips website: " When a letter F appears on the right hand corner of the screen it means the television is in factory mode. To exit from factory mode, press the 'VOLUME -' and ?CHANNEL -? buttons on the TV set simultaneous for 5 seconds. " Hope this helps Michael Junge

SOURCE: VIZIO 52" LCD is on but....no display

If this is indeed an LCD and not a plasma, then you need to replace the LVDS (LCD controller) board.

SOURCE: panasonic Tc-p42x1 picture is good ,but no sound,

First reset to default, if don't work look for firmware upgrade, then make sure speakers are set to on.Actually there is always digital audio output when there is any TV input. However when the digital TV is used, digital bitstream format is output (for 5.1 channel sound). When any other TV input is used, digital PCM format is output. This is normal and indicated in the owner's manual.
Set the receiving decoder in the stereo system setup menu (not the TV) to automatic digital audio detection, not PCM or bitstream. This will enable digital audio when any TV input is selected

SOURCE: Had a power outage now

sounds like you may have also had a power spike and possibly fried the tv. have you tried unplugging the tv for about 30 mins and plugging it back in? some tv's have built in surge protectors that need to be re-set

SOURCE: panasonic TC-L26X1 TV suddenly stopped

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both. In your case I'd concentrate on the power input board.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.

Mum pressed some buttons on amp now the amp wont respond to the original remote or the universal remote. buttons wont work, batteries good and lights up. is there a button that blocks ir signal?


Looking at the user guide it appears that the amp has a standby mode.

See not below on turning standby on. Question can you see the standby light flashing.

I would also suggest using function on the amp to remove any possible issues with the remote.

One would expect the system to return to normal operation by pressing the power button again. If not what do you see on the display.

Note:
Press 1 to turn on the receiver.You can also turn on the receiver using 1 on the remote control. When you turn off the receiver, press 1 again. "STANDBY" flashes on the display panel. Do not disconnect the AC power cord (mains lead) while "STANDBY" is flashing. This may cause a malfunction.

Why am i getting ''please wait try again later'' message


Test the remote control. Use the digital camera , point the r control viewing the camera, and with the camerA ON, you must see the LED I.R ON. see the picture. If NOT you must open the remote and clean the keypads from dirty+ and resolder the cold joint from the LED.
try again. However if the LED is o.k read your owner manual download for free go www. fitness.manualsonline.com

Denon CD deck


This unit needs a service visit. It may be a common problem with that model but to me it sound like a power supply issue as when you play a disc more power is used to rotate motors and move the sled. This is indicating to you that it is in a weakened condition and will soon fail more significantly. The problem may be as little as a solder joint or a defective Filter capacitor which is common in some models of equipment.

How to change from ºF to ºC on the UMC-117?


According to the 2012 manual, 'the LED display only shows F.'
Bottom page 65. Yet the F temperatures are also shown as C in the manual.
http://waterheatertimer.org/pdf/How-to-set-Rheem-tankless-temperature.pdf
You probably have different model, or older model?.?
Older manual (page 15) shows same temperature range with both F and C, but typical of Rheem, the manual is totally vague about settings and say that qualified tech needed to adjust temps beyond factory default range (with no mention of display showing C) ... which is safeguard since the damg product cannot always heat water fast enough to reach higher set points above 120F.
http://waterheatertimer.org/pdf/TanklessOutdoor_95_84_64X_UC_AP15318.pdf

Call Rheem 800-432-8373 and give your product serial number and model number located on side of unit, and ask them.

Don't forget to keep the product maintained to avoid common error codes.

How do you autoscan the olevia 232 t lcd hdtv? I connected an antenna and using a uneversal remote. it just sits there displaying 'no signal'


In the remote, select the input as antenna. It might be now lying as some other input. Normally the TV itself searches for channels. If it is not, go to menu in the remote control, select install-auto and press ok.

My lg tv displays V3.10.1 an does not respond to manual or remote control


It is showing the software/firmware version--seems you may have by accident gotten into a place you should not be in---best answer is get LG on the phone with model number and the V3 information---I doubt anyone here will resolve this issue instantly.

I have a Sony CDP-CX350. I recently discovered the remote will not control anything on the player. The remote has fresh batteries and displays that a signal is sent out. The same display usually shows...


If you have turned it back on then this would indicate the receiving module that picks up the infrared signal is not working and has become defective, but I would double check your manual so nothing was over looked.
