Hi Guys,
I have a Sansui SV-EPD-42QOBP that has a damaged Z SUSTAIN board.
Is it possible for a mains surge to damage the Z SUSTAIN board only.
As a rule I dont do plasma tv repairs, but a customer needs a damage report for their insurance broker, so I took it on.
I do a lot of damage reports on lcds, these range from cracked panels, liquid damage and power surges. In most instances the surge damage is quite evident where you can see damage in the front end of the power supply.
(these surges appear after a power outage and the power comes back on)
I found two swollen capacitors, and the +VS pin(desoldered) dead short to ground.
I am not going to attempt a repair. (i've tried before and the heat sink & plated through holes make chip removal near impossible & the hassle of sourcing one).
Is it possible for the surge to take out the Z SUSTAIN board, yet leave the power supply intact? (you would think the power supply would be taken out first?)
I have the same scenario where LCD's have failed LED lamps, and the customers reckon it happened when they had power outage/ surge.
Once again, is this possible where the power supply is intact, yet something "down the line" is damaged.
Photos attached.
Thanks, Mike.
