The display settings on your computer need to be turned down. Set it to 800x600 and move up from there, if the resolution is too high - the TV won't display it.
This problems,i fix alot models of tvs all diffrent models of tvs but have the same board alway dies.The LCD inverter board is dead.This board help the LCD to have a backlight to go through the Turner board to produce a picture.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish LCD inverter board for the replacement.The board is long in shape.It the easiest board to replaced in LCD tvs.
Thanks for using FixYa.From what
you have described it seems the issue is with the power board or the main board
we’ll need to check few things. When you open the unit up; take a look at the
power board-the board where, the power cords/plugs goes into. You might see
some filter capacitors a little bulged up in the top-If this is the case-this
is your defective part(you can try to replace them-but some soldering equipment
is needed). If not, then probably the main board has gone bad. This is the other
board-where all he inputs are going into. Also check for the Backlight Inverter
Board if the sound is coming fine from the TV however as its shutting off so it
should be either the power board or the main board. All this is only
recommended if you have electrical expertise and know how to solder/re-solder
components.. Please do accept the solution if
the issue is resolved or else revert for further assistance. Thanks Rylee
Most failures on this TV are due to defective power supplies. If the TV does not turn ON, you should replace the power supply. Check this website to buy the power supply adapter and hopefully that should fix the TV.
The solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply. I service these power supplies, for more info write to [email protected]
Open the back of the TV,and look at the can shaped items on the boards.If any of them have the tops,or bottoms bulged out,they need to be replaced.This should get it working again.I hope this helps.If you have any questions,please let me know.Thank You very much!
Do you still have this TV?Sounds to me like a bad capacitor,or two.I just got done fixing an Akai LCT2660 that had four bad capacitors on the power board.Works perfect now.Hope this helps.Thank You very much!
Same thing for me. TV just turned off one day and won't come back on. LED flashes red. Someone said it's because a cooling fan went out. If I can't find someone to fix it I'll take it apart and tinker myself. 32" with dvd built in was barely over a year old.
