There are two ways to connect a converter box.

The simplest is to use the RF antenna cable supplied with the converter. Connect it from the box (the round threaded connector) to the TV's antenna/cable input connector and put the TV on channel 3 or 4 (whichever the converter box is set to). If your set has screw terminals for the antenna connection, you'll need an adapter to switch from the round cable connection to the screws. This may also have been supplied, but you'll probably need to pick one up at Radio Shack or another retailer.

The other way, if your TV has the inputs, is to use the audio/video output jacks on the converter. Again, the cable is usually supplied with the box. This direct connection gives better picture and sound quality than the RF method. The jacks are color coded: red and white for the audio right and left channels, yellow for video. Just connect them to the matching jacks on the TV and select the video input to watch the box. (If your TV is mono and has only a single white audio input jack, you'll need a Y-adapter to join the two audio signals from the box into one. This is also available at Radio Shack. If you don't do this, you'll only get one channel of the sound when watching a stereo channel.)

That's an analog TV and would need a converter box for the new digital broadcasting.

If you or someone you know is comfortable with soldering electronic circuits, you can solder some long extension leads to the speaker terminals in the set, feed them out through the ventilation slots in the back, and hook your extra speakers to them. Just be aware that the audio output circuit was designed to be used with the speakers in the set only. If Toshiba had meant for external speakers to be used they would have provided terminals for you. You may damage the amplifier with the extra load.

unplug it

hold power and action down ten seconds

hold power and action down for ten seconds should reset

The changes that you mention will only effect you if you use either rabbit ears or a rooftop antenna. The over-air broadcast signals are being changed from analog to digital. If you have cable or satelite service, there will be no change.

1. solder the vertical ic first. otherwise replaced the vertical ic.

2. solder the yoke wires.

3. replaced the vertical ic supply capacitor.

That is because the switches of the front panel buttons are stuck or defective.

Try first unplugging power for ten minutes, this probably wont work.

To fix this the TV must be taken apart from an expert, and front panel replaced.

You can enquiry here for parts.

What you can do at home, is getting a replacement remote and using TV with a remote, or buying a freeview box, and watching and changing channels through the box.

You can get a replacement remote here: Replacement Remote Control orReplacement Remotes

My suggestion, if it is supported in your area, get a set top box with 30 channels : Freeview - digital TV from Argos.

My Quaasar televison has sound but no picture what can I do?

you have an intermittent vertical ic or caps . it will need service sorry usually it's not to expensive werepair these all the time

ok you need to factory settings to comeback the normal operation of your TV! go to qulified technician to re settings the TV! thanks! i hope this can help to you as solved!

This can happen if you hook an external amp to the audio output jacks on the TV and those jacks are set to fixed output, but I will assume that you are talking about the sound through the TV's internal speakers. If the picture is normal and the On Screen Display (OSD) shows that volume is being turned down then the microprocessor is putting out the correct clock and data commands. You need to find the audio processor IC which controls the volume, tone, balance, etc. and see if the clock and data information is actually reaching that IC. If it is then I will bet that the IC is defective and needs to be replaced. If you do not have an oscilloscope or experience in repairing PC boards then have a qualified tech handle it for you.

the one stated in the free sq4001 manual or a relic universal remote , rare i bet.

Not sure why anyone would want to repair a non hd TV as the picture quality isn't usable with modern content but if you're doing it because you like restoring something vintage here are some ideas. Some CRT sets use a pulse from the back side of the flyback transformer as a starter voltage supply, it needs this short pulse to start the power supply, it's kind of like starting a gas motor, the starter only runs for a short time then the gas motor takes over, this signal needs to be measured with a scope or a high end meter, this was a common issue with a lot of older CRT sets that use this type of power supply. I'd look at the start up supply as without that the regular supply isn't operatable.

no model TV told at all.nor year made. 1967 to 2004?????? not sure what you are attempting at all first off there are no more VHF/UHF wide band TV now. its all gone. bye bye. HDTV yes , old analog is gone. buried. this TV is NOT CABLE ready, back in 1967 era,no such thing. make relic TV work needs a video to vhf channel 3/4 converter like old Pong or ATARI games had. yes there are converters. to do video to modulated channel 3/4 but not told at all what is your video choices,?sources. DVD RCA video jacks. cable modems do not have those. I bet you have cable modem or a SAT modem and converting HDTV to analog is wow hard. if not impossible one can record a video sources and convert it using PONG adapter. to old CRT motorola quasar. quasar Company ceased to exist in 2004. ! Beside Uwave ovens. and Motorola 1974 sold its television business to Matsushita Electric, now Panasonic https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2047675.m570.l1313&_nkw=+RF+Modulator+RCA+Input+Channel+3+4+Adapter+Output+&_sacat=0 the above will work ch.3/4 VHF with video sources.

You can't., there are too many! Visual ID perhaps. https://www.google.com/search?q=Quasar+remote&rlz=1C1QJDB_enCA643CA644&sxsrf=AOaemvL0VTmVEZKq6ZL80XiQa36s1qdAkQ:1643244756606&source=lnms&tbm=isch&sa=X&ved=2ahUKEwjZ0_vf29D1AhVVj4kEHcJeBwEQ_AUoAnoECAEQBA&biw=1920&bih=937&dpr=1 ..

Your EEPROM is bad, if you can find one and have soldering skills and the equipment to remove and replace SMD devices that's the cheap way to fix( $15) if not replace the main board, in your case with the sound issue it may make more sense to replace the main as that should correct that isue as well

Your issue is .................................
