20 Most Recent Toshiba 32C100U 32 in. TV Questions & Answers

1. Verify the circuit it's plugged into is powered. 2. Change the batteries in your remote control. It requires (2) AAA's. 3. Unplug the TV for several minutes, then try again.

Have you checked whether mains power reaches the power board? Check it first. If yes, the power board you purchased newly should be checked.

The tuner can fail. Did you have a surge come through cable line? I have had tuners damaged after a lightning strike near an OTA antenna. (It took out the amplifier/splitter and the tuners on 2 TVs and a digital-to-analog OTA converter box. Oddly, it didn't destroy the tuner on a second converter box.) Before you assume that the tuner is bad, try resetting the TV to the factory default. Press Menu and select Setup. Highlight Installation and press Enter. Then use the left and right arrows to get to Factory Defaults. Press Enter and then highlight Yes and press Enter. (Enter your PIN if you have set one.) Then use the left or right arrows to select Done and press Enter again. After the TV turns off, unplug it for several seconds. Plug the power cord back in and try to scan for channels again.I hope this helps. Cindy Wells

About which capacitor you're discussing about? Provide more details please. If you wish to get some details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic /Timeslide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name / model number / IC used, in the search box at the top right of the display window.

Sorry. There is no hope.

Ghost? More likely bad remote. Pull the batteries from the remote and leave them out for a couple days, see if the problem persists. If it does then there is nothing wrong with the remote. Good luck.

Might be worth the effort to open it and have a look for loose plugs or a ribbon cable somewhere--if do look for any plugs that are held down with tape near where they plug in.

Sir the problem of your unit is the power supply if you remove the back cover of your unit be sure to unplug it first, then observe the power supply or look for the bulge up capacitor this bulge up capacitor is producing a low and unfiltered dc output this causes your unit to malfunction.


this is the bulge up capacitor if you see this replace it with the same type and observe the polarity. And also try to look for cold solder or loosed solder joint in the solder part of your power supply.

If you see this cold solder or loosed solder, resolder it but be sure not to connect separated pins or joint it will cause much damage to the unit, hope this help good day and best regards.

YOU NEED A VGA CABLE FOR THIS, JUST CONNECT IN YOU LAPTOP AND THEN TOYOUR SCREEN, (VGA INPUT). THEN PRESSING THE KEYS ON YOUR KEYBOARD, FN ( CHECK YOUR LAPTOP KEY BOARD WHICH ONE HAS THE SCREEN SYMBOL ON IT) USE THAT AS A COMBINATION AND PRESS TOGATHER..THIS SHOULD WORK.

Just disconnect all the connectors and make sure you keep track will each screw that you have removed goes, and you be able to get a new board at www.partstore.com

Hi Joseph,

Make sure that you replaced the fuse with exact ratings. Low ampere ratings will not handle current as what the original fuse installed. If still fuse keeps blowing after replacing with the same rating, this is an indication that you have a short on the power supply section. It can't be fixed by replacing the fuse alone. Short usually near the AC line where parts like the following are present.

1. Power Cord - even very low of chances but still to be check.
2. VDR
3. Rectifier diode
4. Main filter electrolytic capacitor
5. Voltage regulator I.C.

This is the common parts that might be shorted and made the fuse blew. You may visit the linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution.

You may also replaced the entire power supply board. Click this LINK to order online.

If you are near to repair shop, you may bring the power supply board to them and isolate the shorted parts, you will save some money rather than sending the entire unit.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

return it. sounds like the built in speaker are wired wrong/ or the voice coil popped on it (would explain the knocking /clicking sound.

red and white colored plugs are for audio, red it right channel and white is left. Plug your DVD player (if that's whay you have) into the red and whte on the tv, some tv's only have one audio in and its usually white, in this case plug in only the white wire from your player. the yellow plug is for video and you should plug that into the yellow jack on your tv. If you tell me exactly what you are trying to plug in I can help you better.

Sounds like inverter boards or backlight boards are defective, there two of them in most Toshibas
and the master board usually dies. If when the tv is on and has sound look closely with a
flashlight shined at the screen you may see movement of the picture, as the screen is most
likely working, just no lights behind it.

The power supply may have died due to bad caps or shorted out, that will be the first place to look.
