Sharp LC-32D42U repair

[budm]

The power supply has no standby voltage due to bad snubber Zener diode (150V 5W) D7907 (1N5383) that shows 50 Ohms in both direction in the STBY SMPS, SMPS IC is TNY268 (https://cdn.badcaps-static.com/pdfs/...87623814b3.pdf).

That looks like a Delta power supply board? What is the part # of it for future reference? DPS....

Re: Sharp LC-32D42U repair

even though this is an old thread ..... perhaps.

I've had a bum delta ps in another Sharp LC32D42U that we have. Swapped ps today and that is the issue.

Last time it was the big zener D7908, but this time both D7908 and D7907 test (compare) bad. Last time I replaced the D7908 with a 10 wt instead of a 5wt, but I have misplaced notes on the 1N number and I don't know the 1N number of D7907 either.

I'd like to find those numbers so I can buy and replace the parts.
Anyone?

Found this thread searching for my TV. Found 1n5383b on Bing/Google to be in the D7907 position. If anyone does respond to this thread where is D7908 on the Delta DPS-178AP A power supply board?
