Plasma TV-power light does not come on
You have burned an internal fuse on the main power board. There are 2 right next to where the main power line plugs in ( after the noise filter ). Yes, you will have to unscrew the rear plate to get to it ( about 24 screws ). You just follow where the lead goes from the plug - you will see where the fuses are - right next to where the plug mounts to the power board. To check this set your meter to ohms and check for continuity - odds are one of the two fuses is done. THIS IS A PANASONIC SPECIFIC FUSE - it cannot be replaced with one that looks like it or fits the same slot. This fuse is a time-delay slow burn fuse and replacing it with anything other than the correct type will cause more damage and possibly total the unit. The panasonic part number is K5D802BNA005 and is available from several parts retailers - just google "panasonic part K5D802BNA005" and many reputable firms will come back on the search. They cost approx. $1.95 US ( so the shipping is probably 7.00 more ) Hope this helps and be careful of the internals and static electricity from your body.

I have a panasonic plasma th46pz80u. Last week
On Panasonic 32LX TVs this is a known fault, repairable by a firmware upgrade. John Lewis in the UK sent out an engineer under their free 5 yr TV guarantee and completed the firmware upgrade for me. The only other store to compare with them for price and service is Richer Sounds but I believe you now have to buy the warranty for 10% of the purchase price. This problem will persist unless the upgrade is completed. For those of you in the UK, I would insist the seller repairs the problem under the Sale of Goods and Services Act as the TV is not fit for purpose without the upgrade.

The Panasonic plasma model I
The problem is most likely a bad SC board, if you can find the board online it will probably run you between $250 - $300 for the part. A repair facility will charge you between $400 - $500 total to fix the unit if that is all that is wrong with it.

Akai LCT 2662 will not turn on
I'm surprise to see the repair shop telling you there nothing they can do.
The power supply can be fix if you take the time to troubleshoot it. However this is not a DIY project.
The failure is in the capacitors that are bulging out of the top or bottom. Quite visibly defective.
