LG 32L46 No Turning On

[Jahson]

Hiya all longtime

Got the Tv dropped off to me the other day, led light on front not lighting up to indicate Tv set is on. Did my visual checks noticed 2 caps bulged C204,C205 will provided photos of boards once I find my camera.

I replaced those 2 bad caps the led to front functions correctly now Green Tv is On, Red its in Standby.

Also did bit of reflow work on what I wasn't sure if could be problems around transformers legs or anything with brown residue.

So I kinda sure the power supply side is ok?

I noticed on switching on a slight tick tick sound coming from the inverter board, so I removed cover didn't a few checks 1st been visual.

Theres 5 smd fuses

Fuse 1 - 3a/63v check Ok
Fuse 2 - 3a/63v check open
Fuse 3 - 3a/63v check open
Fuse 4 - 3a/63v check open
Fuse 5 - 0.75/63v check Ok

Think these most definitely need replacing F2-F3-F4.
This is were I could do with some help been on flea-bay but not sure on the correct part number.

Circuit Side
I315B1-16A

The inverter board has so many numbers underneath green side has
The big sticker
27-D019399
0741HF
008332
I315B1-16A-C302G

The little sticker
27-D019399
T871029.11 LF
E200000743-00

Many Thanx inadvance

for three fuses to be blown other parts on that board may/must be faulty too upload a picture/part number of the invertor board so we can see what were dealing with

The circuit side number brings up the following board.
It looks as though the 8 pin devices (mosfets maybe) are faulty.
This could be because of the transformers being out of spec and operating at a higher current.

Quick update still not found camera will use phone.
By chance found the exact board all numbers matched on fleabay good bargain price £6 lol @ £5pp so great.

Before plugging the (new used board) into Tv i check it against the faulty board, found it to be shorted to ground around those little capacitors where they are seated 3 in a row across the board if thats the correct terminology. So not sure if replacing the mentioned fuses above would of fixed that issue.

Cut to the chase tv is now on working to a certain degree? If i plug my Kodi box in to the HDMI sockets port 1 or 2 it freezes the (Not Programmed) sign that moves around the screen like a screen saver. Tv remote control does not function to commands when pressed.

Got to unplug HDMI cable, also unplug power lead.

Ive tested with another HDMI source been from my Miracast & all is fine both ports working, remote control working fine, Tv been on for over 3 hours no problems.

I waiting for a much better quality HDMI cable to arrive so i can test with the kodi box again, also will be trying connecting to a DVD player. I've only got my kodi box & that miracast as my only HDMI devices i can test with at the moment.

Any suggestions will be helpful.
