Question about Televison & Video

1 Answer

This is a refurbished TV, model # MT-SYTPT3218AB. I have owned it for about 1 year. About 3 months ago, if it was turned off for more than an hour, it would take a long time to turn it back on. Three days ago it lost the picture and sound while I was watching it, but the power indicator light remained green. After that happened I was not able to get it to turn back on. I know more about electronics than most people do, I owned a used car audio repair business. I was the only employee, so I did all the repairs. I suspect that the power supply in this TV has a problem. Can you please help me. Thank you in advance, Michael Lint Michael Lint Email: mlint1@yahoo.com Phone: 702-289-9369

Your experience paid off in your suspecion, I would replace thw poer supply as a whole, Some people would dig further and fund the Capacitors have failed and replace the caps in the power supply. Let me tell you you can do just that but I would not recommend that if you want the tv to last longer then 90 days.

I would seriously recommend you to purchase a new power supply for this.
Thanks I hope my advice helps please do click the accept button for my efforts.

Hi We bought a Sony Bravia 40" 2 1/2 years ago. Model # KDL40EX400. After about 14 months we started to experience something very bizarre. The TV would turn itself off. No lights on the screen. Af


At some point you have to cut your losses, this is the reason I suggest getting an extended warranty with coverage (including the maker) of 3 years, 80 of the 140 sets in our shop are less than 3 years old, if this set had that they would have to fix or replace the set----One reason I choose to answer your question (I do this here for free) is this set ought to have a error buffer, when set fails it will count the event and that also indicates where the issue is.

Most of the Sony sets for the last decade with set off and using the Sony remote: Display, 5, vol down, and POWER will if set comes on bring up a display with a number of shortened items listed----they should all if the set has this be a zero. Any with a number indicates a issue and the number indicates the number of times this event has happened.

You reset it by unplugging it for about an hour, if it still does not work, you will need in-depth troubleshooting.

How do you set up the Soya TV. Is it cable ready?


Hi,

Yes, your TV is cable ready. To set up, you will need to use the original remote and complete the following steps.

1. Connect your cable box to your TV using either antenna (RF) cable or component A/V
2. Press the "MENU" button on your remote
3. Select "CHANNELS" using the up/down arrow buttons on your remote and press "OK"
4. Select "SCAN CHANNEL" and press"OK".
5. Select "CABLE" as the source and press "OK" to tune

The TV should now automatically tune the cable stations and exit the menu. If you need to exit the menu and/or start again just press "MENU" on the remote again.

If you have no picture, press the "INPUT" button on your remote repeatedly until the input is on "TUNER" if you are using an RF cable or "COMPONENT" if you are using component A/V cable.

Your TV should now be setup for watching cable.

Please post back if you need further assistance.

Regards,
BElectric

Tv wont turn on


I have the same problem. I took off the back panel and the power circuit board was fired. You can see burnt brown marks on the components and the circuit board. I did a google search and I can get a new power circuit board for around $55. Very easy to install.
