Do a reset to this set, and check. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Hi Philippa,
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
If your TV, flatscreen, or monitor is more than 5 years old it is more like to have suffered a component failure.
Take it to a repair shop.

I can only assume you mean that the power light is flashing, not that there is a flashing light showing on the display panel.
The speed and number of flashes you get is the troubleshooting code to tell what's wrong with the set. More info is needed.
If audio is OK, the fault should be with its back-light. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis.

This could be too much signal thanks to the Freeview retunes going on. Your aerial is more sensitive at some frequencies, so there's more signal power higher up the frequency range.
A simple and inexpensive diagnosis tool is a variable attenuator. The MA1620 on this page is perfect for that job:
Splitters amplified splitters and attenuators
It will give you a way to reduce the signal level at one TV without affecting the other TVs in the house.

Hi,
I suspect that this is a Tesco TV?
The fact that it scans on switch on make me think that its flash ram is volatile being unable to record the results. I don't know if this is a battery backed memory or nvram which has an old type store.
If this is within the gtee period take it back.
If the menu allows it find factory reset.
It may be that the stored data is corrupt and unable to write over with the new settings.
Some back door resets are accessed by holding a key down and then switching on the television. Another test to try is to unplug the tv for a day as any corruption may be held by standby current.
Greetings when you say welcome screen you mean the lg logo
with the clock below it???
If this is the screen you see its more possible a mainboard failure and not some kind of reset
