I was able to fix this problem by replacing a fuse. Remove the cover (7 screws). Directly behind the fan are 2 boards with 5 fuses on them. The boards are 1 over the other. The fuse I replaced was labeled F5 and on the top board with the fuse facing down on the underside of the board.

According to the operating instructions, you must take it to a repair facility. There are no troubleshooting suggestions for this problem in the manual.

Its showing F70 error on display. Only workd on DVD mode, when i turn it on any other mode it just shows F70, switch power off. All fuses are ok, no any visibly damaged components

The fuse is a part of the problem it is for safety measures
the problem is in between the power supply regulators, capacitors and power amplifier circuit board.
usually a regulator or an output transistor can cause this error.
hope this helps.

What does f70 overloads means

Sounds like either an amp problem or a fan problem. Either one can send a F70 code. Check and see if the rear fan is turning freely, it might just be dirty and can't spin easy

Panasonic SA-he75, displays an F70 error.

The F70 error is a code for "protect". See the link below for a general explanation of protect mode. Specifically for your unit, the output amplifier IC has failed. This can be replaced, but the parts cost will be in the $100 range. Please update this if you have further questions.

F70 problem

Look up "Panasonic F70 error" on Google and you will find plenty of discussion about this problem.

The F70 is a blown fuse error. It looks like you can can the fuse yourself, if so inclined, otherwise send it to a service agent.
