42PQ6000 Clicking fast not powering on

[loadedboyuk]

I have a LG 42PQ6000 seems to be stuck in standby
after plugging in to the wall the only thing you can get is a rapid click (twice a second) from the main power board.

If I disconnect the X/Y boards it makes no differance, if I disconnect the main AV board the clicking slows down (once every 2 seconds)

TV does not power up
X is connected thur the YSUS

Board numbers are
Power: EAY60696801
AV: eax57566204
Y: eax60764001
X: eax60764101

If anyone can help it would be great,?!? I have replaced a few compontents, as I thought I did not have 5v standby but this has made not effect on the issue of the clicking relay

Posting pictures of the back of your tv showing the boards with clear pictures may help you more with fixing your problem

Re: 42PQ6000 Clicking fast not powering on

Common issue a the stby Diode shorting is something like Vb3200 check that.

Here is a pic of the back of the TV.

Not sure what you mean by VB3200?

Re: 42PQ6000 Clicking fast not powering on

Vb3200 is the model of the diode, do you have a DMM and do you know how to check for SC ?

Re: 42PQ6000 Clicking fast not powering on

I can find lots of simlar tv manuals but not the one for this model.

i know how to use my multi meter and check for shorts yes.

have you tried toms site? if theres not a exact one maybe another will be close enough for trouble shooting

Re: 42PQ6000 Clicking fast not powering on

PQ3000 is very close - only a few less features
Terrible picture quality. Worst I've ever seen from a plasma. Dim and washed out. No idea how LG approved shipment (I believe it was the model after the sparklies debacle, so perhaps they gimped the panel drive to make it work without requiring too much re-engineering.)

Re: 42PQ6000 Clicking fast not powering on

found a diode marked VSB3200 shorted out. can this normnally be replaced, or is the short often casued by something else?

Thanks

Re: 42PQ6000 Clicking fast not powering on

Normally just the diode replace it and away you go Common issue on these sets, repaired two previous ones and was just that diode.

Re: 42PQ6000 Clicking fast not powering on

cool, parts on order though various websites have different part numbers for them including

UF5408 (VSB3200 / RGP30) DO-201AD Diode 1A 1000V from ohmsupplies

[ReeceyBurger123]

Re: 42PQ6000 Clicking fast not powering on

You will need a VSB3000 that will work.

Re: 42PQ6000 Clicking fast not powering on

hi did it work?

[ReeceyBurger123]

Re: 42PQ6000 Clicking fast not powering on

We dont know because he never BOTHERED to update his thread. What fault have you got ?

[Mikeyboy2007]

Re: 42PQ6000 Clicking fast not powering on

can this diode be purchased from maplins or RS components ? looking on there website im seeing loads of different ones ? or if someone can send me in the right direction to get one thanks

[Mikeyboy2007]

Re: 42PQ6000 Clicking fast not powering on

would this work ? http://www.maplin.co.uk/p/1n5402-3a-...ectifier-ql83e

Re: 42PQ6000 Clicking fast not powering on

Ohms Supplies Ltd are a local UK supplier. LoadedlboyUK didn't come back on the thread so perhaps it worked for him.

He indicated UF5408 (VSB3200 / RGP30) DO-201AD Diode 1A 1000V

But I don't know if it is a replacement for the VSB3000 which I can't find anything on.

Nah--Dont think its to do with the Mal-Discharge issue--These also suffer from it quite badly.

LG got at by the damnable Greenies and chasing lower power-consumption I think...

Crap set either way! Never seen a good one, always cruddy pictures and nearly always Mal-Discharge too, although--the green fringing/sandy/gritty picture sort rather than red-spots....

Re: 42PQ6000 Clicking fast not powering on

ok thanks. i will order that and give it a try and let you guys know if its works. im repairing this set for someone.

update for you guys, took out that diode and put in the UF5408 (VSB3200 / RGP30) DO-201AD Diode 1A 1000V from Ohm supplies and it was a success so for anyone else having the issue if the diode is goosed then change that and away you go.

thanks guys.
