    It wont turn on from either the remote or the tv itself. would it be possible to change out the power supply or faulty caps myself? I work with electricity for a living but Im sure working on a tv is different in some ways than my job.

  • candy r Mar 13, 2008

    thanks for the help. sounds like i should just trash the tv, probably cost way too much to take it to repair. I know all about caps being able to hold charge and I know all about electronic boards... I would like an easy fix of pulling out a board and just exchanging it. oh well

    Does this only happen with the remote , does it turn on ok from the tv buttons?
    If it does turn on OK from Tv it could be a problem with you remote or a complicated problem in your set.

    If it has the same problem turning on from the TV buttons than the problem most likely lies in the power supply probably faulty capacitors.

Well the best way is to give the job to a professional specially if the tv is expensive! the power supply cannot be changed as this is normally part of the whole board.
If you have done some basic electronics and soldering skills on a circuit board you may try changing the caps, but you must find out which ones to change these normally are next to the switch mode transformer.
Again with out proper knowledge of fault finding there is a risk of wasting your time as it could be something else! it could even be dry joints.
You should try this if you have a friend that has done some electronic work.

    Just to add if you decide to do this job yourself make sure you disconnect the main lead first.
    You also have to watch the large 400 volt capacitor in the power supply these could still have some voltage when you have similar problems like you have make sure to discharge them with a 2kOhm 5W resistor, so you don't do any damage!

My flat screen Sylvania TV is flashing different colors what's wrong


Better late than never. The problem is that your TV is in the service mode. There are many ways this can happen. But, lets just get down to fixin this! With the original remote and the TV on. If the TV will not shut off, do this. Press the left cursor button on the remote, followed with pressing the right cursor. Power off the TV with remote, or press off button on TV.

Secondly, your TV will power on and off. But you have flashing colors. Do this. With the original remote and TV on. Press the up cursor button, on the remote, followed with pressing the down cursor. Power off TV with remote, or press off power of TV. Thanks for asking me, Matt of Martins TV Repair.

Can set up th remote control for this tv with the direct tv cable remote


Here's how to scan for TV codes on your DIRECTV remote

1.Make sure your TV is turned on.

2.Slide the mode switch at top of remote to "TV".

3.Press and hold the MUTE button. This is located above the number 1 button.

4.While still holding down MUTE, press and hold the SELECT button until green light at the top of the remote flashes twice.

5.Then enter 991, the green light on remote should flash twice.

5b. Press 1 again (it will flash twice again), then you press the power on button at the very top right.

6.Point remote at TV and press CHANNEL UP button. Tap the CHANNEL UP button repeatedly until the TV powers off.

*If you hit channel up very fast, you risk going past the code. Pressing channel down will back it up. I alway hit channel up very fast till the tv turns off, then back it up slowly till it comes back on.

7.When the TV powers off, press and release the SELECT button.

*Note: If the green light flashes three times before TV responds, then all codes have been cycled through. Our remote controls are guaranteed to program to your DIRECTV receiver, however your TV may not be compatible with our remote control.

Solution is simple....

First, unplug power cable from the back of your TV. You will notice the flashing light is still flashing. Don't worry, go to the Second step.

Second, keep pressing on the POWER button, located on the panel at the top of your TV, to shut off your TV. This will stop the flashing light from appearing.

Third, Plug the power cable back onto your TV

Fourth, press the POWER botton ONCE, using the same button used in the Second step to turn your TV back on.

Fifth, you will see the POWER light comes on, as normal.

Sixth, using your remote control, press the green button to turn on. Your TV should work as normal.
