Soyo MT-SYTPT3718AB 37 in. LCD Television - Answered Questions & Fixed issues

Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Something short circuit is there at it main digital board.

Does it have a digital tuner or not?

The thing to find out first is does it have a ATSC type (digital tuner) in it or not---if not you may need a set top converter box for this.

Try website like Remotes.com to buy the tv original remote or a very closed compatible one.

Have someone remove the back (who knows how to do it safely) and follow the power cord into the set to the power supply board.

There will be a number of round capacitors (black & gray are usual colors) that look like cyclinders on the board; the tops are silver with creases and should be PERFECTLY FLAT.

What happens is they use the cheapest voltage rated capacitors they can find; the caps are rated in value and voltage---after a few years they dry out and cause problems---a damaged cap will function when it gets hot to some degree so usually the problem is only at turn on.

Desktop computers have the same problem--recently fixed one (had to turn it on several times to get it to operate) and 5 of the caps were puffed up--rated at 10 volts with 9 volts on them all the time---replaced them (about a dollar each) with caps of the same value rated at 16 volts and bingo--computer works fine.

The reason these companies do this is if you buy 10,000 caps at 10 volts they cost less than the same caps at 16 volts---save a few pennies on every unit.

The unit will work for a while and then fail.

Let me know if you have questions with a comment here, the site will email me if you do..

I am here to help.

Hi, If you have already contacted customer support from DIRECT T.V. and they could not help ( that is to say give you a universal remote code), It's quite possible a universal remote code is not provided by SOYO. Unfortunately in is quite common for import t.v. manufacturers to NOT supply their remote controls code. This ensures the sales of replacement remote sales! If you have the original remote I can walk you through the repair process-Sorry I didn't have better news, although I hope I've been of some help. Prodzilla

not true at all. I would try to look on the power supply first for popped capacitors that supply the 24v rail for the backlight inverter.

Having sound is a positive when it comes to repair. This means that only your screen is not lighting.

If you repair the 24v line and check the 5v feed also going to the ps_on (on) the backlight inverter and you still have no picture...you will need a new inverter.


Hope this helps!

power supply unit problem you have bad caps (capacitors) change all the caps or atleast the onces they leaking how do you see if they bad usually they are bold on the top instead of flat. change it with a higher voltage but the same UF. if it shows 10V-1000uf you change to 16V-1000uf or if it fits a 25V-1000uf.

That means there are no more updates for that TV. You might want to get a newer TV.

Go to home setting on remote. Go to audio settings on tv. Adjust sound from there down to suitable level.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electro-medical.blogspot.com/ If blinks continue without any pause, the main board is faulty. Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts. Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location.

Use the remote to choose the input. You can also use the menu button to find the inputs.

If your country uses the PAL TV system make sure the TV tuner is not set to NTSC.

There is a failed part inside the tv that is keeping it from powering up. You will need to have a repair shop look at it to get an estimate.

If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD & Plasma screen are similar, irrespective of its brand and screen size.

Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the sites linked here. It has set-up code list & set-up procedure to many popular brand remote controls. One among it has general set-up codes to check with TVs and other devices are given, in the order of the 'device's brand name list' in alphabetical order. Pull up older posts. Search the sites by type in the brand name to your device in its search box at the top right part of the display window. It will help you to find the document easily. http://electro-medical.blogspot.com/

No.

You would have to replace the tuner board or maybe just good reflow If you need further help, I’m available over the phone at https://www.6ya.com/expert/richard_b59056c0c62ecb00
