Then its working primary good, the fuses but secundary can be bulged capacitors convextopped or leaking ones on the print ? a mos-n-fet can be damaged also there are fuse-resistors inside little circuits to protect to tuner and other places but also, the green colored versions of korean 3w resistors could have bad end wirecaps on it it could be the case but capacitors of Samsung are allways bad in-between 4 a 5 years of the most models tv, s look for replace with 10 volt higher caps and 120 degrees typos . solder pads of heat-carrying active components and loose components by bad solderings cold solder bath on the factory on some places.
first measure for junction of the diodes secundair if there is one shorted it will also stand in protect-mode , if you not find the problem , you can take a variac in order to circumvent the short-circuit protection hihihii then its burning out a few components where it became wrong so ill do that in the early times of the first CRT with sda scl and memory codes and protection in the digital era in tv from analog CRT tv i know that it was very different to repare a 30 years ago TV with variac but if you slowly higher the power on you can in serial place a lamp of 200W between the AC to the power supply to see with a temperature measurement witch active component could be bad.

Can this tv be repaired my husband is getting rid of it it’s a curved Samsung 68 inch
Most things can be repaired and it is mostly down to if any exclusive spare parts needed can still be obtained and the economics of the repair.
The main problem is some manufacturers price their exclusive parts not to sell but the tv is a seriously premium piece of technology and is well worth your interest and further enquiries.
I suggest you check with Samsung if there is an approved repairer in your vicinity - an approved repairer would be best for your purpose and be best placed to advise you though if there isn't one nearby you should call on the services of a local repairer, preferably chosen by personal recommendation from friends or neighbours.
Before you begin your research you should discover the cost of a replacement tv of similar size, design, quality in order to make a cost comparison.
