Repaired two sets, both had a blown fuse (E???) and shorted capacitor (C707). These parts cost me $2.00.
Search for the keywords Hitachi and C707.

I have a Sharp flat panel model LC-20SH4U. The units power LED light is red. No effect (sound or picture) when remote or on/off switch is activated. The LED light slightly blinks.


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.

1. Unplug the TV power cord from the power outlet.
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 this may help;

Regards,

Green light stays on when trying to turn off tv. picture go's off when cable remote is used but green light stays onand you can see that screen is still on?


You need to set up the cable box remote for your TV , now you are just turning off the cable box. Some cable boxes have a switched plug on the back that will turn on and off with the box. If yours has the switched receptacle you can use that to turn the TV on and off by plugging your TV into the switched receptacle. Make sure the TV power is on, the receptacle will kill the power so the clock on the TV wont work. Otherwise you need to set the code for your TVs remote and use the system power button.

follow this steps and fix it. GOD BLESS YOU
  1. Make sure all power cords are connected.
  2. Try pressing the enter/play key.
  3. Make sure the TV is turned on and the input is set properly.
  4. Make sure the TV source is set properly on the TV (This is probably done on the screen; Check your TV manual).
No sound:
  1. Check if the TV and Amplifier (if connected) is turned on and set correctly.
  2. Check if the TV, DVD player and Amplifier are connected properly.
  3. Make sure the TV, DVD player and Amplifier volume are not set to Mute.
  4. There will be no sound output during Reverse Play / Pause / Step / Slow / Search.
  5. If the DTS soundtrack is enabled in the DVD Disc Menu, but you are using Stereo Analog audio, the sound will not work. Try switching the soundtrack to Dolby 5.1 or PCM mode in the Disc Menu.

Sony bravia screen just stays on black and wont go to picture.


It sounds like a main board failure but could be a power supply issue as well. The set will need to be diagnosed

Last time turned on tv picture flashed and went dead, Now when I turn it on it makes its normal clicking sound but does nothing. no power light or sound black screen, set is rarely used. Only thing it does...


Sir this problem is commonly caused by bulging capacitor or loosed connection, if you remove the back cover be sure to unplug the unit. Bulging capacitor is producing a low and unfiltered DC supply, one of the sign is the clicking noise you hear came from the relay. Or try to tap the side of your tv and observe if the tv will react. ekcnoel_9.jpg

This a bad capacitor ekcnoel_8.jpeg
this is the loosed or dry joint it is much better if you use a magnifying glass to determine the loosed or dry solder. Good day and best regards.

Need installation instructions for GVA 100 set top box


Just bought one of these cheap.
Very basic just plug in and it sets itself up to some degree.
- make sure tv is on appropriate AV channel as you'll need the on screen menu to set it up initially using the remote control.
- then set the unit to scan for the tv channels, took about 10 minutes for me.
- NOTE ... there is no power on/off switch. Plug the cord into the 240v outlet and unit comes straight on. You can't turn it off except by switching offf at power point. Or using the standby button on the remote.
- NOTE ... there is also no display on the unit. So yoy have no channel display on the unit. It is all done on the tv screen.

But it does have quite a good EPG and menu guide.
For the price, can't complain.

Just got the tv out of the box, and can not get it to power on. If I unplug and wait 60 seconds I hear a click in the tv and am unable to turn it on. Is the tv bad or is there something else I can do?


Make sure the cord is plugged in tightly at the TV and at the wall.

Try turning it on from the power switch on the TV (not the remote - batteries in remote may be missing or bad (if they came with the set).

Some TV screens appear dark / off if there is no signal so make sure the cable or antenna is plugged in (or dvd if that is all you will use).

Try clicking through the different input sources (Should be a SOURCE or INPUT button on side of set. Use remote with good batteries if you don' t have a button on the set.

If those options fail, put it back in the box and return it - the set it bad. Sorry.
