YAMAHA YST SW315 Service Manual free download schematics eeprom repair...

Because the system is bi-amplified, it is important to replace the wires correctly to avoid phase problems. I don't know how the wires are colour coded, but if it is any help I downloaded the schematic and the wires are numbered 1: Woofer Active 2: Woofer Earth
3: Tweeter Earth and 4: Tweeter Active. Sorry if that's no help. Otherwise it should be easy to trace the wires to see which connect to earth.

Can you please check for any jammed buttons on the remote and/or control panel? Try switching on the TV manually, while removing the batteries from the remote. If you notice same problem, the area to be looked into is around the system control area: like dry solder, leaky/dry capacitors and this should be done only by a qualified service technician.

my speaker sound is not comming

my nobel tv dcl 3482 woofer ic damage i reapir to macnic and lost the ic number please send me woofer ic number

Check the Woofer for continuity and also with an external amplifier.
if there is no issues then the sub-woofer power amp IC can be faulty.
Check the main voltage to the IC, if not present the power section must be traced for a line break, fusible link.
If there is power , then test for input signal to the IC. If so the IC can be the supect.

sir I am using 2.1 creative inspire speakers system, at present no sound is coming in the speakers or woofer, what is the problem.
power is on and after connecting the speakers to woofer from pc no sound is coming. what is the problem. please help me. thanks rajanna

no software for that creative. change the amplifier IC inside woofer which is the out put of all speakers.

The amps are 8-pin CHN 4558CN [K1D142] and 8-pin PHIL TDA8199 [LD8136] The Voltage Regulator is a 14-pin LM324N There is a 3-pin LM7812CN 12-volt regulator... They are in the sub-woofer housing which is held in place by tape so it can be pried off if done with care. Hope this helps. If you have all the cables and wires in place I would appreciate knowing the connection sequences (someone cut all the wiring to the set I have.)
