I have a 46'' Polaroid HDTV model# TLA-04641C that will not turn on (Manually or remotely) The red standby light is on and when plugged in you can hear standard sounds. So it is getting power. I tried to find a reset button but did not find one. I tried unplugging it to see if that would reset it but it didn't work.
What can I do to get my TV to work I have only had it for 2 years max so it shouldn't be worn out already. Please HELP!!
It hasn't been 'unplugged' until you have let it stay that way overnight. There are components that need to discharge and that can take hours.
You wrote 'standard sounds;' did this mean audio or something else?
If you have normal audio but no identifiable video, then the backlight or the inverter for the backlight has failed.
If audio is present, try looking at the screen from several angels to see if you can identify some ghost-like video.
If so, then the above suspicion is pretty much confirmed.
I hate that the modern sets seem so prone to failure, it isn't a good trade-off for the increase in quality of the results.
Most of these are not poor engineering but the effort to build them with the cheapest possible parts inside, often only saving a few dollars, but ruining their reputation.
> that makes sence.
It does; there are fields that build up rapidly and can cause actual flexing of windings and some components.
" try looking at the screen from several angels to see if you can identify some ghost-like video."
My typing isn't getting better with age, the 'angels' should have read as 'angles.'
Since both video and audio are missing, this suggests that the main power supply has failed.
This is often on a separate board since this is one part of the set that is commonly outsourced from specialty manufacturers.
Allow the set to stay unplugged overnight before removing the back panel.
Locate the PS board by looking for a separate board with larger than average components, especially larger blocks and round cans mounted 90 degrees to the board.
The blocks are transformers or chokes and the cans are capacitors.
Examine it carefully and note any series of characters that might be an assembly number. You might find more than one string but the assembly number is mostly added after the board is built while the bare board number is often etched just like the circuit traces.
You can contact the mfr.'s service company nearest you to see if they have an exchange or repair program that may be slightly cheaper than a new assembly.
If you have no luck with them, try:
Jimmy's Parts
They buy overruns and pull sets apart to retrieve assemblies such as the one you need.
Good luck-

No I dont mean audio. Like I said it doesn't turn on. I was talking about the sound you hear when you plug a TV in. Like it is getting power.
IF that makes sence.
