Hello everyone!
This is my first post, but not my first attempt to repair a TV.
So a few days ago I got this Philips TV (TPM4.1E LA), which produced weird symptoms.
There were no 12 and 24V, which was caused by a shorted schottky. I replaced that, the voltages are alright everywhere, but it still refused to turn on or even produce a standby light.
Thats when I removed the cover lid from the U4201, turns out that it badly burnt through, thanks to that replaced diode. It's an MTK MT8222TMMU, and I already found a replacement for it. However in the service manual, it's listed as MT8222AMMU/A.
So my question is, should I go through with the TMMU one, or use the AMMU/A?
I'll attach some images which might help, since I couldn't find a datasheet for the AMMU/A.
Thank you to everyone in advance, who might be able to give some advice!
