SOURCE: Can receive only channels 1 thru 27 although connected to cable with 70 channels.

First you need to check if your set is in the cable mode and not antena mode,if the set is in cable make sure is in the standard cable mode and not another type of cable like HRC,if it is change it and try the autoprogram to set the available channels.I hope it helps.

SOURCE: speakers won't turn on

Have you checked the fuse in your plug. If the fuse has blown it won't work in any wall socket. Change the fuse for a new one anyway, then try again.

SOURCE: No Power

This is a very common problem. Theres a guy on ebay that will fix it for you for 24 bucks plus 5 bucks shipping. When you open the monitor, on the back panel there are 2 boards. One is a power supply board, the other is the interlogic board. The power supply board is where the problem is. I do not know the exact component that needs replacing as I did not test this yet. I do not have the proper test equipment. For 24 bucks, I'm just gonna let the ebay guy repair it. I will report my results here when I get the board back. I'm also gonna mark the components so I know what they replaced.

The power supply is shutting down for one reason or another. This unit has 4 shutdown alarms feeding the main processor. It doesn't take much to trip it and believe me, it's a ***** to find it if it is a subtle condition. The VCR could be shutting it down as well if it is not reset exactly right.

This is what I did with the one unit I worked on; It would shut down after 5 seconds. The picture was good when it breifly came on -- but it shut down anyway.

IC1601 is the shutdown opto isolator that will shut off the supply. I removed it and the set came on. After a few minutes one of the power supply diodes started smoking so I unplugged it. The diode, D1618 was bad so I replaced it and the TV worked. But, I could not put IC1601 back in without it still shutting down. I spent hours searching and couldn't find anything. Since it was my son's TV (which he found at the dump) it was OK by me. BUT, if you remove this IC, (it is a four pin located near the yellow transformer) the set will come on no matter what. Just remember, if there is a problem, it will show up quickly. Maybe a new troubleshooting method? Ohms law troubleshooting? No, unfortunately not. Just be careful and try to find the problem.

If you google this model number, you will find a free schematic that --someone-- uploaded to a free schematic website.

WILL NOT EJECT DISC


What is the model number of your DVD player? You may try power resetting the unit and check if it helps. To power reset, turn OFF the DVD player and unplug the power cord from the electrical outlet for 30 seconds. Plug the power cord back into the electrical outlet and turn the player ON. Attempt to open the disc tray.

Depending on the model number of your DVD player, simultaneously press the POWER + STOP + EJECT buttons. If the disc tray still does not open, simultaneously press the DISC1 + STOP + EJECT buttons.
NOTE: This step may not apply to all models as DISC1 is not available on all DVD players.

If this does not work and if the DVD player has DISPLAY and PREV buttons, press and hold the DISPLAY+PREV buttons for two seconds to unlock the drawer.

FOR SONY PLAYER's

Fuses are not your issue. Look in your owner's manual. Find the procedure to return your unit to "Factory Defaults". I'm sure you just have something switched wrong.

Hello,
Welcome to the Sony Community.

The "PROTECT" and "PUSH POWER" messages will flash alternately when the protective device of the amplifier has been activated because a strong signal was input, or if there is a short-circuit detected. Press the POWER button on the unit to turn off the system, and check the following items after "STANDBY" disappears.

1) Are the + and - speaker cords short-circuited?
2) Are you using only the specified speakers?.
3) Is anything blocking the ventilation holes of the system?

You may also refer to the following link for additional troubleshooting steps.

My sony mhc lx10000 has no audio whenever the display reads speakers B ...HOW DO I RESET IT TO PLAY?


This is for model # MHC-LX10000. All of these answers are WRONG ! Do not listen to these. Its very simple, I had the same problem happen to me today and simply reset the system to the original factory settings. Here's how to do this and is very easy. It is mentioned in the user manual on Page 32. First unplug the power cord. Then plug it back in and turn on the system with the power button on the audio system. At the same time, press 3 buttons - the square/stop, ENTER and the Power buttons. The system gets reset to factory settings and the Speaker B will disappear. You will lose all your presets but the speakers will work once again. What a relief it was to me ! You can then set up your presets again. I wonder why with all these system support techs available here and bragging about how many years they have worked for Sony, none of them could mention this simple solution.

I need the wires to conect two speakers sony sa-va100r


Which two speakers?

http://www.retrevo.com/support/Sony-SA-VA100-Speaker-Systems-manual/id/22986ci669/t/2/

The speakers themselves appear to use standard spealer wire with bare ends. Just get a roll of lamp cord at the hardware store and cut it to the length you need.

Between the two front speakers they require a standard RCA stereo audio cable.

http://www.searspartsdirect.com/partsdirect/part-model/Sony-Parts/Audio-equipment-Parts/Model-SAVA500/0996/0311400/50017803/00001

If you're needing the flat cable the link above is a breakdown of the various components. Perhaps you could contact them and describe which 'wire' you need.

Some other possibilities...

Sony SA-VA 100 won't turn on


You can try a factory reset.

Push and hold down Dolby NR, stop and disc 7 buttons, then push power.

Otherwise it looks like $60 to $100 repair bill. These are not the most repair freindly units.

Good Luck.
