Question about Hitachi 53SDX89B 53" Rear Projection Television

1 Answer

No power i connected a speaker to both tv and external amplier when i hooked up my karaoke. i did this before reading the manual and i did not see the caution sign at the back of the tv that says "use 80 ohm speakers only". it was working ok until it just lost power. the green lights on the board are still on. the fuse does not look busted. can i fix the problem myself? if it needs professional service, how much would it cost and is it worth it? i purchased the tv from a friend a year and a half ago and i don't know how long she've had it. i did not have any audio or video problem prior to this. thanks, linda

I accidently put the rca wires in the wrong audio input/output on my craig cd graphics karaoke player.Could this be why i have no sound?


The RCA outs are designed to send a signal to an external amplifier. That amplifier, in turn, sends the music signal to speakers.
The RCA inputs are designed to take audio signals from another device (like an ipod, CD Player, or computer) and play it through the Craig System speakers. If you sing into the microphone, the vocals will be mixed with the incoming music. However, in these cases, there won't be lyrics on the screen. If you play a karaoke DVD in a DVD player, connect the red, white and yellow RCA cables from the DVD out to the Craig Inputs, the lyrics should appear on the Craig screen while the music plays.
If you mistakenly plug RCA cables into the Craig Inputs and plug the other end into an amplifier's inputs, neither will produce any sound.
Using RCA outs is only necessary if you want to have louder music than the on-board Craig speakers can handle. Of course, you can run the yellow video cable to a TV RCA input to get a bigger lyrics window and the RED and White RCA to the TV RCA Red and White inputs to hear the music through the TV's speakers.

How to connect external speakers to RCA 22LA45RQD

I have a sceptre flat screen i bought 2 years ago (40") the sound just quit can hook up external speakers?


Read the owner manual or check all the inputs on the rear to see if it has those connections---it is also possible a surround system routed from a box (cable or sat) might work to bypass this issue.


and do not forget to check in the set menu that the speakers did not somehow get switched to OFF.

I just got a used karaoke laser disc player ...no manual.....can it be hooked straight to speakers or does it need to go through a receiver?


Hello, the karaoke laser disc player, does it comes along with a self ampilifer if it does, check for the serial ribbon cable that is used to interconnect the disc player to the self ampilifer and connect the speakers to the output port of the ampilifer and not directly to the laser disc player.
If it does not come with a self ampilifer, then you can connect the speakers direct to the laser disc player.
With the following above it will work effectively for you to enjoy the laser disc player...

Mic doesn't work


check the manual. also go to their website for answers. look at the back of the machine and see if it does have a connection to hook it up to speakers. also, if you have a mic see if it has a on/off switch. you could have it in the off position and not on; also, check the machine to see if it has a knob to turn to mic.

Can I hook my TV directly up to Bose 201 speakers?


It depends on the TV audio output connections. Most TVs have low level audio outputs (RCA Jacks) that require a amp but some do have external speaker connections. You will have to refer to your manual or check the back of the set.
