Hi Group, I'm working a Panasonic TC-P50S2. The tv won't power up and no led blinking codes, I found a surface mounted component that is shorted. the board placement # ZD554 the part #VZPTZ6.2BT well I know it's a ZENER DIODE, it's from the power supply, I did a ton of research trying to find anything on it, and I found nothing no datasheet, can anyone help cross reference this part or tell me it's characteristics.?

the STBY5V supply bus. I would guess it's a 6.2 volt Zener diode.
