I doubt you blew the picture tube. I do think you damaged the main board ( power supply board). First I would suggest you check the fuses, in both the main board and also the convergence board ( there are two main boards in your set ). Before you start, always use caution by unplugging the set from the wall. To check the fuses, remove the bottom panel cover in the back of the set by removing the screws. Use a flashlight and observe all the fuses you can find and see if any are opened or burned out. ( if the fuse is burned out, it will be black, you may not be able to see if the fuse is just opened without using a continuity checker ( volt ohm meter ) ). Any fuses you find open or burned out, replace with a like fuse ( voltage and amperage ). The set should work fine if a fuse is the problem. If the set doesn't have a bad fuse or won't work after replacing a bad fuse, then you will probably have to seek professional help. Good luck. I hope this has helped.

Is it possible to watch Toshiba picture frame television with external speakers disconnected from back of television

A filter couldn't hurt. I would also suggest checking the grounding strap. I have also come across neighbors who have installed linear amplifiers on their CB radios which overdrive the signal and cause interference with those around them. Now could these antenna be an amateur radio, or HAM radio, setup? If so, they have different restriction but they aren't supposed to cause local interference either. You can contact the FCC to pursue that further.

Great pictures, by the way. Depending on the age if your set, your setup menu for audio may allow you to change the speaker set up to allow you to disconnect each set of speakers & experiment with the sound quality. You may want to disconnect each pair of wire and blow out any dust/dirt with some compressed air as well as checking for any loose strands of copper wire creating an unintentional ground or short while reinserting the wire back into the connector jack. If that doesn't help, you may want to check the wires going into each speaker and check for dust inside the speaker boxes. You would be amazed at how dust can get into things. Remember, dust has moisture, making it a conductor of electricity. Not much is needed to create interference.

Home Theater Setup - Rear Speakers

When people install their own home theater systems they typically use these small stick-type stands for the rear speakers. This leaves one (or all) rear speaker blasting right into your ear, which is not how the rear speakers should be.

Rear speakers should be mounted two to three feet above ear level or higher, get those speakers off of the stands and onto the walls. The reason for this is that they were intended to add a background effect, they are not meant to distract your from the picture.

If your room (or significant other) does not allow speakers to be mounted up, then move your rears back a bit and aim them towards each other, this will maximize their effect and not distract you from the front while you enjoy your movie.

Toshiba lcd tv 32" making noise by speaker

test this steps and fix it. God bless you

Line noise is feeding in from the AC line. Use an AC liner filter to block the line noise. RF (radio frequency) interference is being picked up by the power line or wiring. Remove sources of RF interference, such as fluorescent lighting or wireless devices not designed to work with audio/video equipment. Wires between the components are on top of one of the components; the transformers are causing RF interference. Be sure that wiring goes behind the components rather than on top or between components. If there is an equalizer in use, there could be a ground loop. Ground loops can be resolved by installing GLI's (ground loop isolators) on the cables connecting to the equalizer.

I have a 2007 trailblazer. The rear speakers didn't work and some of the head unit lights didn't work. I replaced the headed unit and that didn't fix it. I then replaced both speakers and one...

Put new wireing in going to both back speakers, Factory wireing is verry thin end it breaks with age. Change it over to at least 16 guage speaker wire or 12 guage, Your system will sound a lot better.

I am replacing a very old Toshiba cassette/radio and it has only one wire (+) going to the speakers. How does that work? I am trying to install another radio that doesn't work this way.

Hello sir, hi most likely the one wire is the live audio out, you are missing the ground line, the missing wire maybe connected to ground already, just like in car wiring where the other line is the body. if not check your speaker connections, they should have a "+" and a "-" sign terminal. to complete a speaker connection it should have two terminals. No speaker would work with only 1 terminal.

I get interference on car radio from my hd headlights

you will have to try changing the ground location for the lights, and keep the ground wire as short as possible... if the noise still happens after trying different ground locations, then you might have to pull the radio and put a ground loop isolator on the radio... that installs easily and you can pick them up at any auto parts or radio installing shop... hope this helps ya

Only a steady pulse comes out of my bull power

hello, it seems that you may have a bad ground on your amp? turn everything off(pull amp fuse at battery) and go to the amp ground and clean paint away to bare metal! secure ground tight and make sure the car battery is not low voltage! this may stop the pulse! the sound problem of no sound in speakers, if still there! make sure the speakers are not shorts or pinched to ground! this could damage the amp! hope this helps, good luck!

Car stereo installation speakers

Your old unit was a common ground unit meaning all speaker grounds as well a radio ground were the same. The new unit should NOT be connected to this wire configuration. Newer units change the potential difference of the speaker power meaning that the - wire of the unit may have negative 24v on it so IT CANNOT BE REFERENCED TO EARTH OR CHASSIS GROUND.

I would recommend rewiring the speakers to the radio for best reliability and sound quality.
