42mf231d/17 fails to turn off manually or w/ remote.

These 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://electronicshelponline.blogspot.com/

You may have a weak power supply. This would indicate one or two capacitors that are weak or bad. This model may be about 4 years now and this is a good indicator as these capacitors need replacing. The other problem may be the infared board in the TV that receives the signal from the remote may be a problem as well. I would certainly investigate my first thought. The latter is kind of rare. Thanks for asking and show a few hands of support.

Hi
Try this:
Automatic Programming
1. Turn off the device with which you want to use the remote control.
2. Press and hold the corresponding button on the remote control (TV, VCR, SAT, DVD) until POWER INDICATOR illuminates. The remote control is in programming mode.
3. Press POWER button on remote and release . The POWER INDICATOR flashes once and stays on indicating the unit is in Power scan mode.
4. Press CHANNEL+ or CHANNEL- repeatedly until the device turns on.
5. When the device turns on, press ok to store the code.
Good luck pls rate

Hi and welcome to FixYa,

The user manual for a Brookstone 538744 is available here. It is in pdf form and would need Adobe Acrobat Reader to view the file.

Good luck and thank you for using FixYa.

here is the schematics http://www.scribd.com/doc/33598674/Philips-42mf231d-Chassis-Tpe1-0u-Pa

oif the codes in setup don't work for the direct tv remote, here is a code list at the end of the post

Great News!! We can program most Philips Universal Remotes with Automatic Code Searh. Here's how it works on most of our remotes.

Programming with Code Search

1. Manually turn on the device (TV, VCR, etc.) to be controlled.

2. Press and hold Code Search button until the red indicator stays on. Release the Code Search button.

3. Press and release the desired mode button (TV, VCR, etc.). The red indicator blink, then stays lit.

4. Press the Channel Up button repeatedly (up to 300 times) until the device could be controlled changes channel. The red indicator blinks, then stays lit. If you accidentally overshoot the code required, press the Channel Down button to backtrack through the library until the device changes channel. Pressing Channel Up changes direction to forward again. Press and release the Mute button to install the code.

The above assumes that you want to store the VCR you want under the VCR but, Cable codes under the CBL, etc

Note: if the device does not have a chat channel at a button, you should Play (VCR only) or Power instead.

Here is a Code List on PDF that shoud be universal for most remotes. It worked for me.

Hope this helps you out, good luck.

there's no signal comes to you tv that why the screen is blue, the problem of your tv is the tuner, so check the the requirment of the tuner to determen if its good or not.

Hi, that TV is not listed in the code list for your model.. You can try an automatic search by doing the following:

1. Turn off the device with which you want to use the remote control.
2. Press and hold the corresponding button on the remote control
(TV, VCR, SAT, DVD, CAB or AUD) until POWER INDICATOR illuminates. The
remote control is in programming mode
3. Press and release power. The POWER INDICATOR flashes once and stays on
indicating the unit is in Power Scan mode.
4. Press CHANNEL + or CHANNEL - repeatedly until the device turns on.
5. When the device turns on, press OK to store the code.
If the device responds, the remote control has been
programmed. If the device does not respond, repeat steps 2-5.
