Hello friends
My TV stopped working, I need your advice to troubleshoot it.
I found two burned components on the PSU board and the fuse is open.
Those the faulty components:
Resistor of R113 : [B][COLOR="Sienna"]Can not identify the resistor value. please help me![/COLOR][/B]
Capacitor C102: 330pf/1kv
Please let me know if I need to check somethings else!
Please see the photos and scheme attached.
ThanksHello friends

Re: Chinese TV looking for Transformer SYEFD25-T001 in Board TP.MS608.P82
I suspect the transformer is bad and I don't have a schema.
This transformer have got in one pin more than 600V on primary side and after that all the components have 0V. (Secondary has 0V)
All the area around the primary side has high voltage more than 600v....Last edited by atari1968; 03-19-2020, 08:23 AM. -

Hello Friends
I need a schema for that transformer SYEFD25-T001
Also, link where to buy it
I couldn't find this at all
Please look at the added photos.

LG TV 42LW5700 does not power on fully (PSU EAX62865401/Main board EAX64405501)
My LG 42LW5700 doesn't power on. when tv plugged on the standby light is
a very week until I switch power on then the standby light blinking slowly.
After checking the power supply,
I measured the output voltage after switch on and everything looks okay
Please see the attached picture of the voltage test for the output ports.
So probably the power supply is ok and the problem could be on the mainboard EAX64405501,

Thanks #budm
So probably the power supply is ok and the problem could be on the mainboard EAX64405501,
The led is always very dim until I switch on and then the led start to blink (high and dim not in the same rate).
What do you think from the measure? What do I need to check next?
Thanks for any help...Leave a comment:

Re: Need capacitor parameters or schema!
I measured the output voltage after switch on and everything looks okay although the weird safety capacitor (CY101) show 0 volts in switch on while the others (CY102-104) show 220 volts.
Please see the attached picture of the voltage test for the output ports.

Need capacitor parameters or schema!
My LG 42LW5700 doesn't power on. when tv plugged on the standby light is a very week until I switch power on the standby light blinking slowly
after checking the power board supply,
I suspect the ceramic capacitor CY101 that have a 0 ohm resistant.
On P201 I got on pwr-on 3.3V instead of 24V.
I cannot find the board schematic on the web.
and I can not figure out which parameters is it?
please see the picture below.
Any help from the experts will be appreciated.
Thanks!...Last edited by atari1968; 08-06-2019, 03:03 PM. -
