    Go to the audio section of your TV and check the joints of Audio IC using Magnifying glass if there is a ©râck on joints resolder it if the Audio IC is Heating too much its your turn to replace the Audio IC...Problem fixed.

    sir, not all audio problems of a CRT TV are related to the audio ic or the audio ic is the culprit. it could also be the LV Supply, the av signal, the speaker, etc... it will even come to a point that it is very hard to trace the problem..yun ang tinatawag nila na "bangungot". The solution you have posted is just one of them and it is not a guarantee that it will fix the problem right away because there are alot of sections on the circuit board of your tv to be considered.

    anyway thanks for sharing:happy:(y)

  8. Pinaka una sa pag checheck ay icheck muna kung naka MUTE ang TV nyo or naka LOW volume BEFORE sa Speaker and Connection GOING to AUDIO IC.
