Picture of the set with the back off then good clear pictures of each board
and close up of the connectors so we can see the labelling often helps.
Have you tried to find a service manual.

There are some burn marks between big primary cap and resistor (i think is rm801), i think that there is small cap under that glue but not sure

You MUST remove all those Glue.

Re: Samsung LE32R88BD Power Fault

Check for any damage to components due to conductive glue. If there is damage, you might need to replace some parts.

ok thanks tom, not 100% sure how to use those manuals.. what is in place RM801 that looks pretty burnt too at one side. sorry for bein such a noob

Re: Samsung LE32R88BD Power Fault

0.22 ohm 1W resistor.

You can press CTRL+F and type your search key e.g. RM801 and it will find that component.

Schematic symbols are simple once you know the basics: http://highfields-arc.co.uk/construc...es/passive.jpg

Schematics, like the one linked, show how circuit components come together to form a functioning unit, in this instance, a power supply.

Re: Samsung LE32R88BD Power Fault

thanks tom, i will have a read up and get those components and try them out and get back to you.

Re: Samsung LE32R88BD Power Fault

Tom66 does the CM810: 2.2nF/1kV have to be soldered in a specific way like the Caps or can it go in any way ?

[tom66]

Re: Samsung LE32R88BD Power Fault

It is non-polar, which means it can go either way around.

[Mikeyboy2007]

Re: Samsung LE32R88BD Power Fault

ok Tom thanks

Re: Samsung LE32R88BD Power Fault
