SOURCE: Hitachi 55" Plasma HDTV, 1 yr old, suddenly lost picture and sound, but power light still on.

It sounds like a shutdown circuit is being activated. This is normal in cases where the power supply id drawing excessive current. I would suggest that you get this looked at by a qualified professional. This is because this problem may be in the power supply and the voltages can get dangerous in this section of the TV set.

In any event if this is a power supply problem chances are the technician will just have to replace the power supply. Which should cost from 150-250 dollars.

I hope this helps

Check for bulged capacitors on the Power supply board. If none are found I would take it in to have it looked at professionally.

I need OPTONICA CS5400 tv remote


If you wish to buy its original remote control, contact the authorized service centre, or authorized dealer to your device brand. They can either give you a genuine remote control to your device, or can direct you, from where can you purchase a suitable one.
To select a proper universal remote control, you should know about the number of digits to its set-up codes. There are 3 digit, 4 digit, 5 digit, 2 digit and even single digit codes, to some brand devices. After confirming this, check the sites linked here. Both the sites have set-up code list and set-up procedure to many popular brand remote controls. Check which brand remote control has set-up code/s to your device brand, and buy that one according to availability. Brand name of the remote control isn't a matter, but it should have set-up codes in its code list, to the device brand you have.
Please note: Every new universal remote control will have set-up code list, and set-up procedure along with its pack. Never accept a remote control, that hasn't both of this. For more details about the set-up codes, visit the sites.

Universal remote controls are available at most of the electronic spare part selling shops. Visit some on-line sites too, which deals with electronic spare parts.

Restore sound on my Tv, suddenly lost.


  1. Check if the mute button on the cable box/TV/VCR is activated. If so, turn off the mute feature
  2. Verify the volume on the cable box/TV/VCR is not turned all the way down, either by adjusting the volume level on the equipment itself or with the remote control
  3. Check if the TV has an earphone or headphone jack. If so, make sure there are no earphones or headphones plugged into it
  4. Check if the Cable Box/TV/VCR has a SAP/MTS switch (Secondary Audio Program / Multichannel Television Sound). If so, make sure it is set to the proper setting. Consult your TV/VCR manufacturer's user manual for information for your specific TV/VCR. Click here for information on changing this setting on a Cable Box
  5. Check behind ALL TV and equipment (Cable box, TV, VCR, DVD, stereo receivers, etc) and the coax cable at the wall outlet for any loose or damaged connectors
  6. Make sure all equipment and connections are hooked up correctly for the video and audio based on the type of connections being utilized

Panasonic Lumix Fx35 Malfunctioning


Go into the setup menu and scroll to "reset"...follow the on-screen instructions. This procedure might work. If you can't get into the menu because of malfunctioning buttons, try a manual reset...remove the card and battery...press all the buttons...insert the card first and then the battery...turn it on.

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope it may help you;

Lost the controller for Pioneer rear projection TV


Try pressing the "Input" button the front of the set. That should allow you to change between the different inputs. The return button usually returns you to the previous channel you were watching - don't think it works for the input though. Also, depending on the model of the set you have, try downloading the PDF user or owners manual - it will tell you how to use the remote.
