Question about Sharp LCD TV LC32SV40U LC 32SV40U - 32" Class 31.5" Viewable

1 Answer

No response when plugged in

Owned the tv for about a year. Suddenly stopped working, does not turn on when the power button is pressed on both the remote and the tv, and no light turns on either. Checked the main fuse, and it's not broken. The capacitors all appear to be working as well.

Hi Justin,
Your problem is your power supply inside your TV. You need to change the whole power supply unit.

I hope my solution may help you.
Thanks for using Fixya...;-)

My Brother PC 8200 was doing an embroidery pattern and suddenly sped up and went crazy! I can't get it to stop sewing motion except to turn all power off. Stop/Start button is red but non-responsive


*Grin* I use to have this machine! It's a very old machine and may not be worth repairing. *tear* It sounds like the on/off switch is broken and un-responsive. The "Sped up and went crazy", part sounds Motherboard related. You never know; take it to a Authorized Brother repair shop motherboard....

Happy New Year!

Hi,

My living room monitor faced the same issue before.

I called up Acer, and they fixed the power LCD board in the monitor.

Do not buy a new one yet, unless the warranty is over.

My Sharp Remote Control Is Suddenly Stop Working


Ok I just dealt with the Sharp customer support for this problem.

1) You need to unplug the TV for 1 full minute and remove the batteries from your remote aswell (this will reset the system)
2) Hold the power button on the remote for 30 seconds with the batteries still out of the remote and the TV still unplugged
3) After the 30 seconds replace batteries then press every button on the remote beginning with the power button in order from left to right and top to bottom (same way you read)
4) Then plug your tv back in and try the remote again.... and the remote and TV should be back in sync.
