You probably have a blown amp ic or the output transistors. But disconnect the speakers and turn it on could be a bad speaker if it turns on.

Hi,
if the tuner has lost its ability to remember stations, it is due to the low backup battery. Replace the old one by a new 3V lithium battery. Can be the same as used in PC mainboards. If the old battery is fixed with welded metal strips, cut them near the battery. They cannot be welded again to a new battery. Bend the strips close together, so that the battery is hold tight when iserted between the strips. Observe the correct polarisation of the battery, must be the same as with the old one.

SOURCE: Sony LBT N455 - Hi

Although your device can handle up to 5 disks the cd laser lens that reads the disk is only one. So if this problem occurs only at these cds it's a disks problem. If it occurs on various disks try using a cd/dvd cleaner set, a wet one is better. Follow the instructions on the set. The main idea is to put one drip of the included liquid at the set (usually isopropyl alcohol) at a specific place (like small brush) on the disk surface and play this disk. This way the "brush" will clean up the laser lens and after that the cd/dvd player will be able to read the disks. BE CAREFULL not to put too much liquid on the "brush". In case you can, use a Q-tip with isopropyl alcohol to clean up the cd lens manually. In case this doesn't solve your problem, the cd player needs laser lens replacement by a technician.

In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, accept my solution.

Thanks and regards
Stelios

How should I hook this up to a Sony hi-fi stereo?


I would try going into the menu settings on your receiver to make sure that the subwoofer is turned on or that the volume is turned up. If it is a powered subwoofer you can try hooking the output of a phone or an iPod to the input cable just to test and see if you are getting sound through the subwoofer. If that seems to be working ok then you know the problem lies with the receiver.

Since you have 2 receivers, you can either use the Sony STR-AV570X or the TA-AX380. You will need 3 Stereo RCA Cables to connect your CD Player, Tuner, and Tape Player. The speakers connect to the receiver you choose using the speaker input terminals.

Kenwood stereo synthesizer tuner t-85l


T-85L is a component of a hifi system not suposed to work alone. You have to connect it to another Kenwood component (an amplifier like the A85 ) through a special cable to power it on/off. The special cable can be used point to point or as daisy-chained.
