HI folks back again after a long time now i know this subwoofers amplifier contains bad caps but all previous research involves only to humming which is documented on here and the caps to replace, my issue is the subwoofer just died dead no issues just kaput!! no power lights nothing.

i only have a digital multimeter to test things but somewhere i had the schematics sent to me from monitor audio and forwarded them on to a chap but never got a response i will desperatley try to dig these out.

240v is present inside.

not much to go on at this stage...

Re: LG 50PJ550 adjusting volume by itself

The panel controls are touch control only I believe no buttons

Hi folks onto my 3rd LG fixed 2 so far with the help posted in these forums

So here goes as title states volume intermittently goes all the way down or up picked the set up cheap knowing there was an issue but could not find anything when googling prior to purchase,

Guy said it just appears on screen now and again

When got it home volume was switched off he must of been going through a amp sepreratley turned sound back on, left it on about 2 hours then it started to turn itself all the way down with led constantly flashing at zero.

Re: Lg50pg3000 sound but no pic.

Replaced top buffer after finding continuity by checking both sides of ribbon connectors and adjusting vy vsc on ysus board think someone had tried fiddling with it previously when seller claimed they had it from new and no repairs to it.

Liars back panel screws had obvious damage and a couple stripped threads but I did not check upon collection

So I paid £40 for tv

New buffer £55 set now up and running

£95 and I have got 50" plasma in my front room

Re: Lg50pg3000 sound but no pic.

Sorry for jumping on thread, just joined so a pat on the back to all that contribute.

Just picked up one of these cheap and surfing net thought it was worth a punt,if I can fix it myself.

Same problem or do I have to start a new post?

Sound ok.

No picture at all,

Disconnected both buffers no change.

No heat at all on buffer heat sinks or y-sus board.

On powerboard 6 heat sinks warm one stone cold.

Only have a Beckmann hd110 to...
