Re: green light comes on for 2 seconds and then nothing

Most of the time the led in front of the tv will blink red and that will tell the technician wich circuit to look in. if it does blink at all when it shuts down then the problem is more than likely in the power supply. the part number for that is 313819875691

Tv is 4 years old yesterday it lost its built in freeview channels. when trying to get the menu up it appears for a second then goes off. Tv still receives sky and picture is good

Hello pip_o

It's possibly a defective digital tuner, but the vanishing menu suggests a more serious (and expensive) fault with the main/AV board, assuming it's an LCD TV. It's impossible to be certain which one without doing some testing, but due to the inherent dangers with high-voltage electronics, I don't advise on self-repair for TVs.

If you're looking for an inexpensive solution and the TV is no longer covered by any warranty, I'd suggest buying an external Freeview box to connect to your TV. This would also enable you to upgrade to Freeview HD. Being 4 years old, your TV will not have been fitted with a DVB-T2 (Freeview HD) tuner.

If you want to try this solution, I can recommend the following box, which is great value at just £25.

They are described as "reconditioned", but I've bought and installed 2 of these for my own customers recently and both have been brand-new. The majority of these are unused returns which Tesco are consequently not allowed to sell described as "new". For a lesser known brand, I've been quite impressed with some of the recent Technika products and they are easy to install and come supplied with all the necessary cables, etc. Additionally, if it doesn't work for any reason, you will be able to return it under UK Distance Selling regulations.

Before purchasing this (or any other) Freeview HD box, please check your TV has a spare HDMI input socket as SCART cannot carry an HD signal. If you don't have a spare HDMI socket, I'd also check your TV has a spare SCART input socket or you will need to disconnect your Sky box every time you want to use the Freeview box - which brings me to my final point . . .

. . . Off the top of my head, I can't think of any Freeviews channels which aren't available on Sky, so as long as you can still use your TV for Sky, do you really need to spend any money on it?

Hope this helps. Please let me know if I can be of further assistance.

I cant make the freeview box work without the operating instructions

OK - please follow these instructions carefully to setup the Freeview box. If you get stuck at any point in the instructions - or anything I've said doesn't make sense or match what you can see - just post another message here and I'll deal with each problem as it arises.

1. Switch the TV and Freeview box to STANDBY. There should be a red light on the Freeview box;
2. Connect the aerial cable to the freeview box. Make sure you are connecting this to the correct socket. This should be labelled "RF IN", "IN" or "Aerial/Antenna". If you have connected to a socket marked "RF/TV OUT" or "TO TV" or something similar, it wont work;
3. Connect the SCART cable to Freeview box and the back of the TV;
4. Switch the TV on;
5. Switch the Freeview box on - you should get a green light on the front of the box;

Most TVs will automatically switch to the external input when a SCART device is switched on while the TV is already on. This is why you should switch the TV on first.

At this point you should be able to see the installation / setup screen for the Freeview box displayed on your TV. If you cannot see this:

A. Press the INPUT button once on your SAMSUNG remote control once. This is the button in the top-right corner of your remote control.
B. If you still cannot see the installation / setup screen, press the MENU or SETUP button on the remote control supplied with the Freeview box.

The instructions from this point forward will be different if you had to press the MENU / SETUP button on the Freeview remote before anything appeared on the TV screen. If this Freeview box has been used before the installation screen will not appear, but you will get at on-screen menu after pressing the MENU / SETUP button. If this happens, please let me know and I will provide alternative instructions for setup.

Assuming you have been able to access the installation screen, it should be easy enough to follow the instructions on screen from this point. Use the UP / DOWN / LEFT / RIGHT arrow keys on the Freeview remote to highlight the relevant options and then press OK / SELECT to choose that option.

I don't want to make this too complicated by providing alternative instructions for every possible scenario. Please run through the instructions above and make sure you are getting an installation screen or "menu/list" displayed on the TV. If you need further instructions from there, I will provide them in another message.

Good luck - I'll await your reply.

I can not set up my freeview on my samsung 52 inch LCD can u help me step by step as I hav no instructions thanks

Plug your aerial into the freeview box. Connect a scart lead from the freeview box to your TV and switch on.
The freeview box, if new, will search for channels itself and as your TV will recognise that it is plugged in, will auto switch to the freeview box.
If it is not new, select menu on the freeview box and follow the instructions for tuning.
There is nothing to tune on your TV as you are using a scart lead.
Hope that helps.

No Signal On D/TV

You may lose some channels when you retune the TV as the channels have been rearranged. To locate them look at the EPG although you may still find that some channels are no longer available on FREEVIEW. See the following link for additional information

If the above process does not work then check the link above for additional information and also visit the accompanying site links below to find more information for your model of TV / FREEVIEW box.

Can't retune sharp aquos lcd tv

This is the best place that's near the manual you need.
They have the LC32D44E manuals, but not the "BK" at the end. I think the "BK" just means BLACK.
But, I think it will work for your TV.
Here's the link:

Click on the "Sharp Europe - Manuals and Download "
Then, Operation Manuals
Then, LCD-TV
Then, put your TV model# for the search.

Green light then nothing

I had exactly the same problem When the TV was switched on all I could see was a flashing green light. After cheching the TV internals and not seeing a problem including the power supply unit which looked and checked normal. Here is what I did to get M TV working again.
Disconnect it from the power supply. Hold down all the buttons simultaneously i.e. the on/off, the volume, the programme, menu buttons, all of them simultaneously and Plug it into the power supply again.
Lo and behold My TV jumped back into life after an absence of about 4 weeks.
Try it yourself exactly as above.

Best of luck.
