It helps to have some heat under the board, that is for sure.

I had a look on those heater plates Robert. But they simply were too expensive to order including shipping and handling to the EU. Things become twice as expensive to get them here.
So 'not very expensive' is relative and they probably are only affordable if ordered within the US of A.
I have a very cheap heater plate with a PTC heater element from China though. That were the only affordable ones. And I bought an affordable stand to mount my Hot Air Heater in for those special Hotfix jobs. So I have my hands free while working on pcb repair. This one:

I noticed that you mentioned that before Menahem. I only wonder how that is bad since Samsung makes besides LCD TV's also those purple Li-ion 18650 cells that they say are amongst the best? About 40 to 50 years ago it was Sony and other companies from Japan that they said made the best products. And in the early days Sony was just a small starting company and their slogan was something like: "we are small so we want to make the best products you can buy to grow". The center of the electronics industry keeps shifting to other countries all the time. And with these failing e-caps and other components it is hard to know exactly who made them.

I am glad that I got a heating platform for heating the bottom of PCB's. It works great and they are not very expensive. I also recently purchased the small LED strip rework station from Shop Jimmy. It will be easier replacing and reflowing solder on LED strips and tiny boards using it instead of my larger platform station.

No, I do not agree. Better to replace them if you have some, or they are not expensive.

Since Nov 2016, Harman Kardon, JBL, and AKG are ALL owned by Samsung.

So expect to see a huge drop in quality in the components which are installed into the equipment of those brands.

Thanks Beh, these electrolyte capacitors keep failing a lot especially in these Amplifier sets at higher currents of the Endstage at around 50V.
