ha ha glad you got it working
! could be a capacitor or thermal regulator maybe more likely a capacitor that is most common thing they have cold spray at radio shack or electronic repair supply store or website you can spray individual individual
parts and pinpoint /isolate that way and if you are comfortable soldering new parts to the board you can do that I wonder if the folks you bought the t con board would exchange
Tcon board and credit your $30.00 toward a PSU board ofc they would probably expect you to pay shipping .
OTOH if you find the fault on your PSU board it might be cheaper to fix the board sometimes I fix them for$3 or $4 US in parts
In any even ether way you decide ton fix it it beats paying $5- $600.00 usd for a new set to replace one that was otherwise working OK ..CHECK THIS OUT Repair Kit, LG 42LC7D-UK, LCD TV, Capacitors, Not the Entire Board $15.95 us kit includes 9 capacitors some solder a desolder wick and link to on line instructions . about twice what you would pay just buying capacitors but convenient. LCD alternatives has web site you can find generic instructions on for free just another option if the prob is a capacitor or two (likely )
I bet if I had a dollar or euro or GBP for every CCFL/LCD and LED/LCD set that gets tossed out in one year for just a bad cap or two I would have millions !
repair shops here charge ~ $ 250.00 to fix that ofc they have their diag time + hourly rate and fixed overhead it's just what it is.
and when you can buy a decent tv for $250.00 - $600.00 now it's hard to justify a $250.00 repair on an older set so kinda tough for repair shops .
even a modern $3-$400.00 set can out perform an older set that costs 10 times as much .
one thing I'm glad of I went from CRT to flat panel and skipped DLP or RPTV altogether those thing had way to many issues !
I worked on a couple of those and decided they were not for me now you can't give them away.
I don't do it for a living but I fix stuff for friends now and then.
Oh I will need your postcode so I can invoice you for consultation services
just kidding !
It will probably go out again something is failing if you decide to replace any capacitors make sure to get same uf value voltage can be higher for example you can use a 30v where a 20v goes but voltage can never be lower t they must be low esr 105 degree spec
or they will not last . Panasonic and Nichicon are good brands amazon has them so do Digikey and Mouser on line Radio shack usually does not have 105 degree spec .
capacitors are polarised like a battery the stripe side is always negative and must be removed and replaced the same way it came out or it will fail.
caps typically run about .80 ea US from mouser and Digikey or maybe 1.50 on amazon but if you are in UK you probably have plenty of sources there. .
shipping is a lot cheaper at amazon though .
thumbs up are first the little green thing on the right bottom in the blue box here just left of the multi button
cool maybe the board is cheap also I'll take a look at shopjimmy.comLooks Like about $80.00 us for a PSU board ofc if you do order one use the part # on the board itself the parts can vary within a given set model
might be cheaper maybe $5.00 -$10.00 + cold spray to fix your board if the filter caps are bad I usually replace the 3-or 4 next to the bad one also
Shopjimmy.com is out of stock of th 3 possible part #s but maybe someone in UK or on ebay has one I'm assu[/SIZE]ming that is your location by the set model #
I thought I would post this so we can just point to it
I made a new thread about power supply diag and repair
if you get time and want to check it out maybe let me know what you think?
Looks like you are on third base no outs
so you will be on home plate soon.Edited by tubetwister - 9/23/13 at 3:40am
