Hello

I got today Sharp TV again.
The problem with it is that the TV is going from standby. There is no picture or sound. I try to access service menu bat nothing. When the TV is on is not responding to any buttons which are on the TV. Customer told me that the TV was plunged in with hair dryer which blow up. And from that time is not working. The PSU is looking OK. I think so.
That somebody had this problem before? Schematic manual can help.
Thanks

If the led is green, then one of the following parts in the power supply
could be broken.
IC403, IC404 KIA431.
F404 micro fuse
IC401 MP2A5060 Power control.
Check the voltage against the manual

Check C440* (2200uF/6.3V) and C441 (220uF/6.3V), check 5V (always) is not low.
