Hello Everyone,

I need help locating a source to buy this Ref. D5693 Part No. B0BC6R600005 Zener Diode, thanks.

Here is the picture.

take the other diode out of the IC to the left and measure the "knee" of the zener. Should be the same diode.
RLZ6.8B Brown Yellow Green
Are these colors correct?
btw... I think it is a Rohm LL-34 package Zener Diodes RLZ Series

Hi CapLeaker, thanks for your reply.

Yes, you are correct on the colors. D5693 is shorted on the pictured board, on another A board that I have (the measurements is 321 and with the probes flipped 698).

Diodes can measure weird in circuit, so test it out of circuit again. Zeners are hard to check with the DMM, unless it is shorted. If it is leaky, you need a Zener testing device, but if you have another board, just change the Zener out.

Yeah you need a proper zener tester to find the breakdown voltage, a DMM usually won't output enough voltage.

I just got my TV going again with an A board I had ordered off of eBay for $24.99. So, awesome it worked. (TV had 10 blink code)

Did you progress with the zener issue at all. I was just looking at the cct and i get the impression it's for protection so if it was just that zener shorted but the cct was not with it removed would it have worked without out it?

Hi tw2005,
No, the extensive zener diode testing was beyond me.
