Help master!!!! TCL 21H91US model... OK sya sa umpisa then nanginginig po ung display at garalgal ang tunog....

Pinalitan ko ung dalawang 25V 1000uF E-caps sa paligid ng vertical IC pero ganun pa rin... Di ko napalitan ung iba kasi wala pa me pamalit... Vertical section lang kaya probs nito master?

Thanks!!
