Question about Toshiba 65H81 65" Rear Projection Television
I have a 65H81 hd toshiba had a power surge and fried main power board. Can that weaken the rest of the items if that is the only wrong. I don't want something to go wrong later because insurance is taking care of it. would it be better to replace the tv
I have been servicing televisions for over 20 years and I have never had any luck on a lightning strike repair. There are too many variables in electronics and IC's and these repairs can be very lengthy. I would ask for a replacement rather than a repair.
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

There isn't really an absolute answer to your question.
The power supply affords some protection to the rest of the set when the components designed to prevent short-term power spikes activate but their primary purpose is the protection of the supply.
There is surely a fuse on the line-side of the supply, then there are two more devices normally included (they cost little) that will force the fuse to blow if a certain line voltage peak is encountered, a type of resistor that is actually a semiconductor that has little effect until its design is exceeded; it then looks electrically more like a dead short, causing the fuse to blow.
The other device doesn't do much after the first few cycles of AC and is there to reduce 'inrush' current.
Well-designed supplies will have fuses on the output side of the supply that protect specific voltages and circuits.
Could the low-level circuits have been affected? Yes, but in some cases, only a working supply and time would show up some kinds of failures.
In addition, I always include the suggestion pasted below:
If you live in an area of frequent lightning strikes, investing in a 'whole house' surge arrester makes sense.
These are installed in the main breaker box and any brand I've seen comes with a $10-25,000 insurance policy to replace any dead appliances that fail despite the surge protector.
They cost $150-250 US plus installation which you can save if you are afraid to DIY.
