I have an ASUS TUF Gaming F15 with an RTX 4060 that is about a year and a half old. Windows shows Code 43 for the dedicated GPU, and a technician told me the GPU is "shorted," but they do not perform board-level repairs. The laptop previously had a power-related failure and was repaired, after which the integrated Intel graphics worked but the RTX 4060 continued showing Code 43. Using the integrated graphics also produces horizontal black lines across the display.
I'm planning to get a second opinion from a technician who specializes in laptop motherboard and GPU-level repairs in the Philippines. Could a laptop RTX 4060 problem like this be repaired at the board level, or would the entire motherboard normally need to be replaced? Could Code 43 be caused by the GPU's power circuitry, solder joints, firmware, or another issue rather than a failed GPU chip? What diagnostic tests should a qualified technician perform to confirm whether there is a real short or another fault? Is repair likely to be worthwhile compared with finding a replacement motherboard or donor laptop?

A replacement motherboard may be more practical if the GPU chip itself is dead, but compatible boards can be expensive and difficult to source. A donor F15 with a damaged screen or another non-motherboard fault can sometimes provide a cheaper replacement board. Compare the repair cost and reliability with the value of the laptop before proceeding.
It’s worth getting a second opinion from someone who specifically repairs laptop motherboards at component level. Reballing the GPU is not automatically a solution and may not help if the chip or its power circuitry has failed. Ask for a written diagnosis and an estimate before approving work.
The RTX 4060 is soldered directly to the laptop motherboard, so there usually isn’t a separate GPU board to replace. Code 43 only tells you that Windows has detected a problem; it does not prove that the GPU chip itself is physically shorted. The fault could be in the GPU power circuitry, memory, solder connections, firmware, or the GPU die itself.
A proper board-repair technician should diagnose the board rather than start with a reball or chip replacement. They can check resistance on the relevant power rails, inspect for shorts, verify the GPU’s power supplies and enable signals, test the surrounding VRM components, and examine the board under magnification. Tell the technician the symptoms and that Windows reports Code 43, but avoid insisting on a specific diagnosis based only on the first technician’s wording.
