'Suppressing' the five hindrances is not the method of the Pali suttas.
In the Pali suttas, the five hindrances are 'abandoned', 'purified' or 'cleansed' using wisdom, as explained in MN 19, MN 20, DN 13, SN 46.55, etc.
Abandoning covetousness with regard to the world, he dwells with an awareness devoid of covetousness. He cleanses his mind of covetousness. Abandoning ill will & anger, he dwells with an awareness devoid of ill will, sympathetic with the welfare of all living beings. He cleanses his mind of ill will & anger. Abandoning sloth & drowsiness, he dwells with an awareness devoid of sloth & drowsiness, mindful, alert, percipient of light. He cleanses his mind of sloth & drowsiness. Abandoning restlessness & anxiety, he dwells undisturbed, his mind inwardly stilled. He cleanses his mind of restlessness & anxiety. Abandoning uncertainty, he dwells having crossed over uncertainty, with no perplexity with regard to skillful mental qualities. He cleanses his mind of uncertainty.
Having abandoned these five hindrances — imperfections of awareness that weaken wisdom — then, quite secluded from sensuality, secluded from unskillful qualities, he enters and remains in the first jhāna: rapture & pleasure born of seclusion, accompanied by directed thought & evaluation.

Jhana and abandoning the 5 hindrances are interrelated, but abandoning the 5 hindrances alone will not get Jhana. The main things to get to the 1st Jhana is vitakka & vicāra. You have to establish your mind on an object and then apply sustainable effort to retain your mind on the object. It is though this effort that the 1st Jhana arises.
