Hi guys I want to share my experience with this model, maybe it could be helpful for the community 😊 this tv comes with only led blu/wite blinking all the time, so I check the voltages then i didn't have any standby voltage, so looking on primary side everything was ok(mosfet/ Bridge rectify and so on) same results on the secondary side (both diode rectify was OK) I didn't find any short, looking deeper the ic controller don't ave any vcc power, so I keep going on the components smd everything was OK also strip led was oka,but I hear something (like pulse and I was right blinking and pulse at the same time, refreshing soldering of power supply notting changed, I almost going to order the ic controller but wen I touch the main board the led on the tv stopped to blinking and turning red,so it appear to have every voltage and the tv turn on. Thenni found a very difficult bad connection in that area (circled red) i hope it could be helpful for someone here i waste 4 day almost getting mad😝

What you circled is an audio power amplifier.

Hi man thanks for the reply, yes I know, probably about bad connection in that area the board was in protection modeor something like that., hi made me almost mad,that why i share my experience could be helpful to everyone 👍The connection of chip itself was okay, bad connection was around it smd components so I decided to refresh all of them, after that tv is on since yesterday.
