SOURCE: why wont my tv turn on? a red light just flashes

Right now, your TV is in " Protection Mode". A damaged part has occurred inside on one of the power supply boards. The red flashing light is a trouble code for a tech to trace the trouble circuit path.

If you have electronic experience with circuit boards, you can find a Service Manual for the TV on the internet for less than $20. This Service manual will have the schematics, red light codes, circuit diagram, and part number list you need to fix the board.

SOURCE: wont power on

Replace your capasitors on the power circuit board.. They are junk to begin with..New ones should power the screen back up.. Had the same exact problem.. now works perfect..

My 32LG350 wont turn on. I just pluged it for the first time i bought it like a month ago. it was working but suddenly it turned off by itself and wont turn on either by pushing the TV on/off boton neither...

Try unplugging the the TV from the power outlet for 30 seconds to a minute and plug back in again. Try to turn on again. Some TV's have to be in a "ready mode" to operate by remote - so besure it is in that mode - or use the power button on the TV.

Good luck!

Most likely, the problem is a defective Main Processor Board. This is the board with the antenna, RCA and HDMI plugs. You cant repair or replace component parts on this board, so dont even try. You must replace the complete board. The TV says Sylvania, but it is a bloody Funia TV. Several years ago this foreign company bought out broke-azzz Sylvania . They are still carrying the Sylvania name since Sylvania was a popular TV name in the 70s. Every electronic company in the USA is now owned by the Chinese, so call Funai and order the part from them. Dont be surprise if they dont have a clue what the heck you asking for. America and all electronics have gone to the puddles. Do you know why? GREED.

try pressing the channel or volume buttons. They turn on the tv as well. Maybe the the remotes might cooperate with the tv.
