20 Most Recent Toshiba REGZA 42 in. Flat-Panel LCD HDTV - Page 7 Questions & Answers


The best solution to this problem is to call Toshiba directly and ask for assistance. Any TV repair company/shop will probably charge you an automatic fee to assess the problem, and then tell you it's a very expensive fix. With just the model and serial number of your TV, an easy 5 minutes will get you the answer you are looking for.

This is from the owner manual

Notes:

If you forget the password, press DISPLAY four times within

Five seconds while the TV is in password entering mode. This
allows you to reset your password.

You should be able to buy a universal remote to fix this problem.
Can you get into your main menu.? If yes, try reseting to factory default. If asked a pass, try 0000.this should do the trick.
Hope this helps.

Hello,

There is no audio because HDMI connection between Macbook and TV does not support sound. The HDMI you used does not have audio. In order words, you are not using the right/correct HDMI cord.

You need to connect with a single cable that carries both audio and video like the Kanex iAdaptĀ® HDMI V2 - Mini Display Port to HDMI Adapter with Audio Support, or the Dr. Bott 9180-MDHK - Mini Display Port to HDMI Adapter II, both of which are linked below.

So endeavor to get any of the above cord and problem should be solved.

I hope the above makes sense to you.

Good luck.

See if you can unlock inputs by going to a Rename input option.

I suspect the power supply to be slowly going faulty. Without the proper power going to the other components, EX: backlight inverter, mainboard, etc. The picture can become distorted and lines can appear from both the mainboard and T-Con board. Before you continue to run your tv, you need to get it repaired (powersupply) or risk further damage.



Please rate if this helped :)

Here is an example of a common problem on power supplies, popped capacitors:

The LCD screen itself often cost more then the tv set itself. If you have accidental insurance you might see if they cover this, otherwise this will make a nice lava lamp like art display for a bedroom wall.......

Hi evansw591,
Power on the unit in the dark room then shine with the flashlight directly in the screen, you will barely see the images. This is because your backlight is not functioning. The following reason is the caused.
1. Power supply - missing B+(supply voltage) coming from this board feeding the inverter board. This is caused by faulty transistor, dried/leaky electrolytic capacitor, open fusible resistor.
2. Inverter board - even the B+ is good from the power supply, if the fuse, driver transistor, driver transformer is faulty no output to the backlight resulting to black picture.
3. Busted backlight - even inverter board is good but if this is busted resulting to black picture also.
Diagnosing the fault is technical and if you don't have necessary tools and test instrument and can't fix it yourself, I would advice you to look for an experienced technician to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

I suspect that the switch has a fractured solder connection or that it went bad all together..The only real way to check the switch is to take the tv apart and check it with an volt ohm milliameter. If it feels like it is not clicking then most likely the switch is bad now. But if it feels like it is working correctly it is most likely a fractured solder connection and needs to be re-soldered, The only other variable would be that the connector is broken or that it just came unhooked. That would be an easy fix. Good luck. HDTV GURU JAY.....

Hallo,
Setahu saya , penggantian transistor pada model-model LCD atau plasma jarang di lakukan, karena beresiko kerusakan komponen yang lain. Jika memang mau melakukan penggantian part , sebaiknya di pastikan dulu kerusakan penyebab rusaknya transistor tsb. jika yakin tidak ada yang rusak, transistor seperti model apa yang kamu cari bisa di cari di internet.
Atau tulis no part nya , mungkin saya bisa bantu.
Terima kasih.

If you have Accidental Insurance Cover on your household insurance or covered by other means then you will be offered a replacement TV. If not there is no cost effective answer as to have it repaired is generally more costly than a replacement item.
Contact and authorised Toshiba service cetre for advice.

Electronics stores don't sell bases for TVs.

Each TV comes with one base, each base comes with a TV. The only way to get a replacement base would be to contact Toshiba and ask them directly for a replacement. For this to work, you'd need the model number of the tv. This can generally be found when you look at the back of the TV, it will have the label on a small sticker somewhere on the back.

Once you have the model number, try doing a quick search on Ebay. Someone may have an old base there that they no longer need, otherwise you're stuck with a wall mount or with contacting Toshiba.
