Why wont my palsonic TFTV3915FL won't turn on. Any ideas

sorry about your issue but the Tv you have is generic low grade and not even worth 100 to replace all over the internet

I suggest you go buy a new TV because the one u have is not worth paying anybody to fix

The main power supply regulator section fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Try the front panel button labeled Source; it's the second button from the left. (The first button is the Power button.) All of the buttons are on the right hand side of the bottom frame of the TV. Use the Channel Up/Down arrows to navigate through the list of inputs. Try waiting for the selection to take effect. (The documentation says press OK or the Volume Up button. Sometimes, the Source button on the TV functions as an OK button. This isn't clearly identified for the Palsonic.)

If the HDMI input is greyed out, the TV may not be seeing a compatible signal from the source. Try turning on the device when the TV is off, then turn on the TV. I'm not sure if this TV will correctly see the signal from a computer. However, on some laptops, you'll need to enable the external video first. This is disabled to save power. Then turn off the computer. Finally, turn on the TV before turning the computer back on.

Palsonic has the manual available for the TFTV492LED on the product (discontinued) site under the Downloads tab. See http://palsonic.com.au/archive/led-tv/tftv492led.htm . The direct link to the manual is http://palsonic.com.au/customer_service/led-instruct/Palsonic_TFTV492LED_Manual.pdf .

I hope this helps.

Check stations MPEG format . Check if it is MPEG4 and check if TV can decode MPEG4 . A firmware update may be available on tv and may fix it but it has the risk of turning the tv into a brick if something goes wrong during a firmware update.
suggest contacting palsonic to see if firmware possible and which one to use.

There might be some loose solder terminals at its main power regulator board.

It will be very difficult to get a sutable universal remote for this set. You can try. That's all.

use the code '9999' and keep searching. it took about 8 minutes to find my Palsonic. then release the off/on button!
