[vlad_]

This part has since been modified to prevent this, new P/N is RDENU0154FCP2.

See: Attachment 36378

Sharp asks for a new RDENU0154FCP2 money (Price
Rank BW !!!). Why should users pay for factory errors?
I will cut the path and solder three zener diodes of 150 volts.

I also had problem C4-00
A malfunction of the high-voltage unit is detected.
Out of order: transistor, diode and fuse.
The photo is attached.

Today checked: After the replacement, ordered from ctha transistor, diode and fuse, the board earned as it should!!!
Transistors from China went for a long time, but they came. They have no analogues! https://ru.aliexpress.com/item/5Pcs-...608.0.0.H57lYY

I checked this out , i have ordered the fuse and Transistor (as a referencetype) .
the diode dont have a Type printed on her Surface . Also i solder it out and Test it by normal way . They dont have a defect .
I replaced Transistor and fuse. Modified with the three Zehner diodes and Test the Board.
Heureka it works.

Made this with 5 other "c4-00" boards and all of the will working well.
