My Mother purchased a LG 32LT75 TV (with built in 160 GB PVR) in Nov 2008 for about £550. From day one it gave problems, but my mother just put up with it (see this thread http://www.avforums.com/forums/lg-fo...lg-32lt75.html). To cut a nine page post short it boiled down to a combination of software upgrade (finally had this done Feb 2011 - LG did for free since known fault) and the digital switch over (Mar 2011 I think). Just got it working right when it developed a not switching on fault/switching on with sound but no picture (Jul 2011). LG refused to repair it (must have known it was a hardware fault now) and actually advised against having it repaired. Decided to have it repaired in Sep 2011 (£70 - not bad) and was fine again for 7 month when the not switch on/no picture returned, sometimes taking ten minutes to turn on. In Jun this year my mother decided she'd had enough and wanted to replace it.
This is where I came in being that she asked me to get her the new one (not a LG this time) and take the old one away. So, whilst looking around for the new one, I did some Googling and found several YouTube video and this website, all pointing to poor capacitors being the problem. Working in IT I'd come across this problem many years ago with Dell computers but I thought, by now, it would have passed into electronic history but it seem not. I got the new TV and took the LG to my house. So here's the strange thing, it came on first time and continues to do so. One thing, my Mother never switched the TV off fully; she'd been told to leave it on standby and only turned it off and on with the remote. I tried to tell her but she came up with all sorts of reasons not to turn it off (I should have known “switch it off, switch it back on again”). To see if leaving on standby was the problem I did leave it for a day but it still came on next day.
I wanted to see what had been repaired in Sep 2011 so I opened it up and straight away I could see that at least one of the capacitors had been replaced. I also noticed one of the large 450v capacitors looks wrong, it could be swelled but I'm not sure. I removed the board and, well I'm not one to rubbish other peoples work but the soldering is not the best I've seen. I can only assume it was done when they'd had a hard day and could hardly lift the soldering iron!!!!. I actually bought a 2nd hand board off EBay for £40 (Rev 1.4 rather than 1.3) thinking it would be a sure fire easy repair but the capacitors on that where worse than mine (strangely not the same ones had bulged), though it was said to be working. Fair dues, they did refund my money, including return postage.
So that's my quandary, do I leave well alone whilst it turns on or what. I think the poor soldering might want re-doing but the large capacitor looks a little tricky (is it soldered from both sides of the board ???). Any advice would be welcomed.
P.S. Just to make you chuckle, my Mother did have one other strange problem with the telly. Being partially deaf she always had the subtitles on and there had been two adverts, about a year apart, which, every time they came on would show the first line of text and then totally freeze the screen, sound would be OK. The only solution was to switch off/on with the remote. If I hadn't have seen it with my own eyes I wouldn't have believed it. My only thought was that the text contained some letter or graphic that the TV could not cope with. Any other guesses.
