Have Tevion 6722 LCD fitted with CV106LT V3.0 main board slight sizzling from speakers.
This set uses a TDA1517 audio o/p chip, I suspect decoupling capacitors since the noise sounds like switch mode type ripple from one of the dc-dc on-board converters.
Can anyone throw light? Thought I ask before 'going on safari'. This is a 12V telly..... seems to run OK, I did swap the inverter because one of the transformers was rattling... the protection plastic looked 'cooked' but yet the set worked OK, nope, not the power supply I tried another.
