Question about Televison & Video

7 Answers

My Magnavox LCD TV made some crackling noises inside the cabinet, and now it will not go on until I keep pressing the power button for about ten minutes. Then, the screen will flash bright white lights every so often. The little green light at the bottom right hand corner flashes on and off for several minutes. Then, without warning, the picture finally comes on the screen. I went through this proceedure every morning for several weeks. This morning nothing would come on. Not even the little green light. Can this be repaired? What is your estimate of cost. It was a $1400 set. Thank You

    It blinks regulary every second for 10 minutes, at least. The white light flashes once or twice in short bursts, then stops unless I hit the power button several times quickly. It does not stay on---just quick flashes.

    The model number is: 37MF331D/37

    I have given sweet rascal all the info he requested, but he has come forth with no information as to what may be wrong with my Magnavox LCD TV. Someone else please give me some help. Thank You. Henry Tobler

    The response from Jigsaw sounds plausable, but another analysis would help me make a decision as to whether the cost of repairs might make it more reasonable to buy a new TV. How much does a circuit board for this model cost? What would the total job, i.e., labor and other materials likely add up to? Thanks for your help. Hank Tobler

  • hftobler1930 Aug 14, 2008

    Yes! I am completely satisfied with the results. Junoon007 and Jigsaw are A#1 in my book. Thank you. I will refer this site to dozens of friends and acquaintences. Hank Tobler

The majority of LCDs failed due to a defective or almost dying power supply. In a few occasions the inverter board that control the light fail as well.
A fair price to pay for a repair is about 1/3 of the price of that LCD or if it's less then a year old, it will be still under manufacturers warranty.
Let me know if you need further assistance.

Sir,

Try to unplug it from the wall and plug it back. This will force a cold reboot, which may help.

Also check...... The blinking power light seems to me to suggest that the driver for the backlight, or at least something in the (switched) power supply, is toast. Usually it's the transformers, sometimes the transistors that do the switching. This is actually not that difficult to repair, but you'll need to bring it to an electronics repair shop. I would say $50 diagnosis, and $100 repair are the most it should cost. Anything above that might be a bit extravagant. Always ask for estimates before any work is done,

thanks
good luck

This is due to a power surge which may have affected the main board. Was their any storms lately in ur area. You need to change the circuit board of the LCD.

Hope this helps. Yes i know it sucks when ur TV dies but investing in a surge protector is the best investment

I lost the booklet with all the codes for my remote and i need the code to work my tv my tv is a symphonic


I suggest you try these steps..

1.Turn the television set on by pressing the "Power" button on the set.

2. Find the "Code Search" button on the Philips Magnavox remote. This button will be labeled or will be a different color than the other buttons on the remote (depending on which Philips Magnavox remote you own)

3. Hold the "Code Search" button down for about ten straight seconds. The light on the Philips Magnavox remote should then stay on.

4. Starting pressing either the "Up" or "Down" channel button on the Philips Magnavox remote. Continue pressing the same button until the television responds to the remote. It could take a few minutes for the channel to change so you'll need to have patience when searching for the remote code in this manner.

5. Press the power button on the Philips Magnavox remote once the channel has changes. If the device shuts off, press the power button again to turn the TV back on. If the TV turns on, the remote has been programmed correctly. Repeat the entire process if your remote is not programmed.

I hope this helps...

Need operation manual


You could try this site:
http://www.universal-remote.net/philipsmagnavox.html
but I would use the auto-search so that you don't keep having to punch in codes. A description of this is as follows: Begin by switching on the device you want to control. Press and hold the "code search" button on the remote until the red led remains lit. Then, press the button for the desired function ("tv", "vcr," "cbl," etc.). Press the channel up button and press the power button. Keep pressing the power button until the device turns off. Hit the "mute" button to store the code. The search is done. I hope this helps! -Der Strom

Is it only one time? If it is out of the speakers this could be going from analog audio to digital audio. It could also just be the cabinet expanding and contracting.
