Philips 55PUS7303 LCD lines

I have bench power supply

this is wromg... u need to have the 12v from the tv self for example on the MB LVDS socket u have t-con 12V...( pins 1-5 i think ) connect jumpers direct to f101,,, solder it not just touch

[lotas]

There is no need to change which motherboard the problem is in the panel (in the buffer strips), if the panel is AUO, then as always the TVS diodes assemblies, take a photo of the buffer strips on the left and right sides.

do it again and check VCC on the winbond spi on t-CON if there > 3V

Again, you can't prove anything, watch the video to see what the problems are with these panels!

[lotas]

Carefully remove these assemblies from both sides.

we don't, argue .. only i hate some one suggust scrap TV with out prof of test... Youtube or edit video for me no go.. what i share here only what i know and faced.. other matter will let my self out.

[rtstorm]

I remove the 4 diodes and guess what? tv work :-) Thank you!
is this ok to leave panel without those diodes? What are they for?

[lotas]

Well, we saw it, it's good that we didn't order the motherboard, and the same problem would have remained!
You don't need to install these diodes, they are more problems than they are worth.

[rtstorm]

Yes, thank you. Hope this will help someone else with this kind of problem.

[lotas]

you are wrong

So where am I wrong?

[Diah]

ESD can be moved as i said before--- ... they are not JUST DIODE,,,, as they are controlled with Freq. this i wrote before,,, this freq generated and monitored by MB.-- oscilloscope will show you.. not ohmmeter. say its diy .. i will accepet it... but don't say issue or repair
