Bought mine from Aliexpress. Usually the shipping is pricier than the
board.
Kaya mas maganda, kung maramihan ang kuha.
And maybe tip someone to install it for you.
The repair guys would most probably have ordered 5 or more units in one shipping if a lot of users inquired, so you can do the math with what they charge.
If they can bring it down to 5k, I'll maybe go that route.
This is a risk because usually you need to check fuses, voltages and which board is the culprit. But since it is a known issue for the f5000, the risk is lower.
Telltale sign is blown components on the backside of the ysus.
Again I have to put this out there- Checking voltages should be a part of the troubleshooting because it's what could've caused the ysus to blow in the first place.. But don't do it if you don't want to and just take a gamble.
Anther risk to consider - getting a defective board form the seller. Bear that in mind. Returns or refunds could be a pain. The repair guys might offer warranty on theirs.
Good luck with whatever you choose. Iba tlaga relaxing image ng plassma, oled lang kapalit.
