Hello

So my tv has started doing the famous blinking with the standby led. (i did not know they had a blink code witch I did not note it down)

I hoped it would just be a simple case of a capacitor that went BOOM! but none of them have blown the top so now I have no clue what to do.

The TV is a Philips 47pfl6877T/12 I live in Denmark but for some reason, 90% of all I find on google with this tv model is in polish/Russian witch won't help much.

I did manage to find a service manual, but I can't find the places on the physical print to measure on.
I have taken it out to do a closer visual inspection and can't find any damaged parts on the PCB. all I got to work with is a somewhat cheap multimeter and a soldering iron

Is there anyone who would be so kind as to assist me in trying to fix this tv?

I know it will take some time, and is far from a 5 min thing but I'm willing to put in the time if it means there is a chance I can repair it compared to buy a new tv

my current knowledge of this is very basic

PKTKS:

Unlikely to be just a cap.

This CHASSI  uses a proper troubleshooting procedure

The manual is very handy - and as you already found it you should
follow the "SETUP" in Diagnostic (Service) mode primary mode

Once you start the manual will guide you in converting the error codes
to figure out what it is wrong or at least some clue to start

A considerable practice is needed to open and deal with such CHASSIs

the proper service mode page is shot here as attach...
find that page to start the "SERVICE MODE"...

ZaXaZ:
it won't turn on at all, and I cant get it to flash again so that makes if very hard to get to use this "SERVICE MODE"

also i fail to find nay translating of blinks in the manual?

PKTKS:


Yes don't expect that it will magically 'turn on'

The Service Modes each has it's own reason to troubleshoot
some particular section

The ERROR CODE table is in the next page... of my shot

To enter all the modes they also suggest their tool (should be
some sort of firmware probe)...

I doubt anyone outside the authorized should have this..
so we need to carve the tips on the manual

It looks that your version of the manual may be missing
or be just a summary ...

Two more shots to see the propr pages

It may still be a defective capacitor. They don't always go as far as have their vent blown up. They may just inflate a bit (bulging vents) and that'd be barely visible. They may even dry up without any significant external sign.
As a first step, I would still unsolder all the electrolytic caps (there are not that many), control them and change them anyway.
Also look for dry solder joints. From the pictures it's hard to see well.
