Damage power supply board

[Mixergr]

Dear All, I need your help to identify the exposed part of the power supply board.
Item damage is the D501.
TV3206-ZC02-01(A) KB-5150 Universal Power Supply Board E59670 P/N 303C3206063 is the power supply board.
Is from Grundig tv G32LCD.
Thanks.

you picture is a bit small, but from other pics on goggle there are a pair of resistors and a mov by the looks of it D prefix makes it a diode

What is the issue with the board ? these a well known for bad caps

the tv receives the orders to open and close (can see the led red-blue) but no sound and no picture. That part D501 blow up the front part gone and we cant to know the specification on it. All the other parts, capacitor, resistance, diode, transistors remove most of them checked and is ok. looks only this part damage .....

Shop Jimmy sells a repair kit for this power supply board.
It doesn't indicate what parts are included in the kit but there appears to be a TO-220 diode included.
Is that the only TO-220 diode on this board?
If so, that would be the blown diode on your power supply.

Otherwise shooting them an email to get the parts list for this kit will get you the part number, and outright ask if the included diode is the D501 replacement.

is it just the 24v line that's gone down ?

A bit more digging

Dual diode rectifier MBR20200CT ( alternative part SBR20200 or SF20LC30 )

Edit. just come across the schematic https://www.electronica-pt.com/esquema/lcd/tv3206-zc02-01-100w-lcd-tv-power-supply-sch-67482/
