Cable is plugged into wall and I use remote to turn on and change channels. It has been fine until it was unplugged for few days
Expert:  Shahid replied 5 months ago.

OK, is that remote came with TV and have Toshiba mark or cable service provider send it?

I got it, so TV is hooked directly with cable from wall and there is no cable box.

Does TV scan any channel when run auto tuning in TV menu?

Customer: replied 5 months ago.
I have reset tv settings to restore settings to favtory default values and also had it scan all the channels
Customer: replied 5 months ago.
I have also tried to plug in at a different location and changed the cable still no tv reception.
Expert:  Shahid replied 5 months ago.

OK, I'm working on it, give me 5 minutes please

Expert:  Shahid replied 5 months ago.

Please check the cable pin is connected/ screw securely and tight on back of TV so the tuner of TV can get cable signals.

Press Menu and select Installation then Terrestrial and select Channel Program to run it, this should scan available channels and save the data in memory.

Please note while channel program runs, does it show any channel numbers etc?

Customer: replied 5 months ago.
The cable pins on both ends are securely attached . When it scans it shows the number of channels. Right now at 70% naumber of chanels found 3, digital channels 112
Expert:  Shahid replied 5 months ago.

OK, let the scan process finish itself then check if TV shows channels?

Customer: replied 5 months ago.
Scanning completed still no picture
Expert:  Shahid replied 5 months ago.

This is odd, do you get channel sound from TV internal speakers?

Customer: replied 5 months ago.
Sound is from the tv
Customer: replied 5 months ago.
There's no sound from any channel just fuzzy screen
Expert:  Shahid replied 5 months ago.

OK, but TV showed numbers of channels during scanning?

Customer: replied 5 months ago.
Customer: replied 5 months ago.
Should HDMI-CEC be on
Tv auto input switch be on
Tv auto power be on
Device auto be on
Expert:  Shahid replied 5 months ago.

OK, it seems EEPROM (memory) chip failure, this chip stores channels data while scanning, since TV tuner worked to scan channels but EEPROM chip didn't save it so TV shows no channel when channel tuning process completed. I'm really sorry for this news as it is hardware related failure and need to replace main board of TV where this EEPROM chip is mounted.

Alternate option is to get 'digital to analog TV converter box' that has its own tuner, connect the converter box into AV/HDMI input of TV and hook the cable into converter box antenna input, select correct input in TV to get converter box home screen and run channel scan with converter box remote to get all available channels and watch them on this TV, this way you wont need to take TV in repair shop, converter box would be available approx $30 plus from local store and ti will resolve the problem.

I trust my input will help you out. Please feel free to respond if you have any additional questions.

You're doing fine with TV settings, channel browser settings are correct mentioned in your previous reply.

Customer: replied 5 months ago.
Very disappointed
Expert:  Shahid replied 5 months ago.

I understand, but electronic part/ chip can fail any time without any notice, I'm really sorry about it.

Expert:  Shahid replied 5 months ago.

I wish I had better news about TV issue, alternate option of converter box will resolve the problem.

Thanks.
