Re: Dish Network VIP622 Power Supply Ticking
After thorough troubleshooting, i found that C50, C54 and C55 are the main reasons behind these PSU failures, but i have no values unfortunately.

Re: Dish Network VIP622 Power Supply Ticking
Would that be a suitable replacement ? 50V, 0.1UF, 1206 package[/QUOTE]
Hello Cheebster,
Did you end up replacing C55? i can confirm that this capacitor is the reason behind most of your psu's.
I had the same issue with at least 6 of them. i never got lucky identifying the value of it.
in some other cases, i had C50 cracked as well, i tried removing them with hot air, they just crack in million parts, never got lucky with those 2.
Please let me know how did it go?Re: Dish Network VIP622Leave a comment:

Dear Budm,
Thank you very much for your help, i followed your instructions after checking all the components on the heatsink, it turned out only the thermistor is dead, replaced it with a new one and now i am watching TV.
Tx guys,

Hello Gusalot,
do you still have the TV? i have a thermistor that jumped, would you be able to find the rating on it?

Re: Samsung LN55C750 PSB
I just checked the bridge, it seems fine.
from the other hand which ever component was there is labeled HS805 and not NT801S. are we on the same wavelength here?
