Sound defect in Sony KV2170GE
I have 21" Sony CRT tv, model KV2170KV which looses its volume gradually from loud to soft and evantually ends up buzzing. This happends intermittently.
I've tried to knock the TV when the fault appears but this doesnt help. So an dry joint might not be the problem. Recycling the power to the TV sometimes solves the problem. Any idea where can I start? Thanks in advance. |
