Hi Cat,
Don't have a shematic but have met a few - and sorted.
Power – Yuyang YP2632T 05.02 Rev A2

All the best, and sorry about advice - Chris.

Thank you all!
And for advice and for advertising. But I'm used to analyze failures and diagrams. I'll try to make himself part of the scheme. What do you get - lay in the forum.
Denial appears simple - no light is on standby and will not turn on.
Search query scheme can not be removed.

Hi Jordan, and thanks.
You and ChasHyde found more duff caps that I have noticed.
Hi Cat,
Translation dubious, but guess no S/by led is the biz - Sometimes a main board problem - Best of luck - Chris.
-
Hi, Turnip!
I absolutely agree. Therefore, first check the power supply. Does not help - I will look at the main board.

Hello friends. I need help.
I plugged in the power supply YP2632T 5 volts (SB) with ON / OFF. The 12 volt relay does start but I do not have the remaining 5 volts. I do not have 24.33 as well.
It replaces C133,213,214 2 C218 capacitors that seemed to me damaged.
It will be possible to take an electric scheme or give me an outlet for this problem.
Thank you very much.

Hi Carlos,
Seen a few, replaced -
C214/C221/C222(all 1000/10) C202/C203/C204 (all 1000/35) C213 (2200/16) - Chris.

Ok ... friend. I'm going to replace all the condensers that are on this list that you sent me.
I'll give you some news soon.
Thank you very much
Congratulations to this Portugal where the sun shines.

Hello friends.
I followed your councils and replaced all the capacitors.
All of these capacitors have been replaced by new ones.
C202-C203-C203-C204-C205-C207-C208-C210-C211-C213-C214-C218-C2219-C221-C222 and further C133.
The fault continues because I do not have the 18.24 and 33 volts.
Could you tell me some solution?
It would be possible to send me an electric scheme.
From now on I thank you for all the attention you have given me, and I look forward to your openness.
thank you :41:

Hi Carlos,
AS LG do not manufacture the power supply themselves, they do not include it's schematic in their service manuals - something to do with
copyright or other - I don't know. I just uploaded the manual for the 32LX2D to this forum. Schematics are very disjointed, but take a look
at it if you wish to see if it's similar or helpful. Bruce

Guess lucky as mine have been duff caps, nothing else.
Anyway, attach a nice piccy which might remind some folks of other issues - Chris.
-
I'm sorry for not sending the photo of the source.
My source is the same as the photo sent to you.
Thank you in advance for your cooperation,
Well, if I know the solution to this breakdown, it's been a long time since I posted it on the forum.
Thank you :sign0085:

Hello friends.
After you have placed new capacitors in the power supply
and check that the relay acted.
Making the 5-volt (SB) bridge with on / off. Remaining 18 and 32 Volts had not.
So far I had not yet connected the power supply plugs to the rest of the TV.
When I turned on the power supply I checked that the 18 and 32 volts are already in use.
The LCD is working correctly.
Thank you all for your attention. :72: :051bye:
