OK my LG 42" Smart TV decided to pack in last night despite it being only 4 years old. Flickered then No Signal and now I only get a Red light flashing and the LG logo screen. Does not respond to anything.
Do I look in to fixing - google suggests the Main boards go on these at £26 each and look simple to replace or do I just get a new one? Seems prices have tumbled - I want bigger than 42" with Smart capability for YouTube etc. and HD with Freeview / good sound etc.
I don't have Sky/Virgin just bog standard freeview.
Tesco have a 55" LG for £550 - about the max I want to spend (but do I really want another LG!) and Currys have a 50" JVC with a free wireless soundbar.
Any reccomendations appreciated.

I can't help you with main boards and such, but if I had an LG that packed in after 4 years I wouldn't be looking at another LG to replace it. Get a Panasonic, they go forever.

Or a Sony Bravia.

Quality TV's albeit slightly on the expensive side.

Had mine 8 years with no issues. Will definitely buy another Sony when the time comes.

I have two Sony TVs. One's about 8 years old, the other about 4. No problems with either. I had a Toshiba that died after 3 years, wouldn't go there again.

Sony or Panasonic for me next.

I had an LG do a similar thing on me and it was just a capacitor that had blown. £5 bag of assorted capacitors from Maplins and a steady hand with a soldering iron and it was fixed.

I found a how to on-line.

For 26 quid it defiantly worth a punt to fix. Or 400+ for a new telly when maybe the old one needed 26 quid thrown at it..
