Most buyers stare at the wood colour finish. They miss the wall behind it. A console hangs by its anchors alone. If the wall crumbles, the TV falls. That is the real risk. You want a floating look, not a falling hazard. The aesthetic is a lie if it breaks.
Hollow blocks are common in older HDBs. Concrete beams need expansion bolts — these hold the weight. A 150cm console with a 65-inch TV weighs roughly 25kg plus the unit. That load transfers directly to the fixing points. Check the manufacturer spec sheet. It is better to be safe than sorry. You need to know the wall density. Concrete holds much better than brick. Long consoles distribute weight differently. A 240cm unit spreads stress better than a 120cm one.
New BTO flats usually have solid concrete walls. Resale units vary wildly. Some walls have hollow cavities hidden by plaster, so you cannot guess. Drill a small hole first and use a stud finder if possible. This step saves a lot of headache later.
Don't trust the sticker weight. Trust the anchor rating instead. A sturdy frame on weak anchors is just a heavy pendulum. Safety comes before style because you live there, not the wall.
