There is no burning smell or power surges.
I checked all the connections and they are ok
During the 75 seconds it is on the sound and picture is great.
Appreciate the "Ask Me". With your permission, I would likewise be posting this reply in your original post here.
Repairs of course would require familiarity with electronic circuitry and components, use of a DM and a soldering iron and access to to a service manual or at the very least a schematic diagram with voltage measurement.
Assuming the above and you are considering a DIY (do-it-yourself), perhaps the easiest and fastest would be to do a shotgun approach, i.e. open the unit and re-solder most of the solder joints with particular attention to the power components such as resistors, transistor, ICs, transformer (including the FBT). Of course one can never be sure which really is defective but the objective is to repair with no in depth diagnosis. Another component type to check would be the big capacitors right after the diode(s). Look for any visual indication of bulging/blistered, leaky or anything out of the ordinary among the power capacitors (and even the other components), if found/yes, then replacement(s) would be needed.
Other than the above, further diagnosis requires that you operate the unit with the back cover off and determine if it is heat related. This could be done by powering the unit, wait the 75 seconds, quickly unplug and feel for any component that heated up. There might be a different smell to it also. Of course safety precautions when working with live sets and/or units just unplugged must be observed.

Too generic of a description. List more detail.
are there any lights on the set
did it make any noises or smells or unsolicited imaged or operation?
is the power plugged into the cable box? did the surge kill it?
did it ever work after the surge?
too may question not enough information

if a power surge shut down the unit than a circuit, capacitor or fuse is blown and or burnt and you wont smell that most of the time and since it does have power fuse wasnt blown so a circuit -diode-capacitor is fried somewhere problem is common for an electricial damaged tv but to diagnose an electronic tech would need to tear it apart
Can you describe where the odor is coming from. Is it coming out from the side panels on the tv set itself, or perhaps the plug, on end of the main power wire. Check around the electrical outlet. Make sure nothing else is plugged into the same outlet. It sounds as if some of the electrical components on the circuit board are burnt or burning out. Tv may have experienced a power surge, etc. Check also if the power plug is heating up. Be careful and smell around top side vents on tv. Be sure and unplug the set before leaving it unattended if you cannot locate the source of the "burning wire smell."
hi,
may be ur tvs lamp side have some problem. may be the lamp over heated and burned. just open its lamp cover ann check it.
also check its power supply input point(near fuse) there is an MOV (used for voltage surge protection) is burned or not. if there is any voltage surge it will get shorted and the fuse will blow off, protect the power supply for any further damage. check the fuse also. if found open then check the MOV. insert fuse only after replacing the MOV.
ok
That is probably the power section about to fail. The burning smell is going to be from overheating components. You will have to take it into either an akai repair depot or a local tv repair and have it looked at. Get an estimate first. The repair cost on this could be cheap if itis obvious and the repair gys are on the ball or it can be pricey if they just replace major parts (typical). Also have a good idea of what replacement cost is so you know if it is worth fixing.
check of fluid leak from the tubes, check to see where the burning smell is comming from. could be anode, hv wire, splitter, surge caps in h-circuit, but it sounds like a high voltage transformer. what is your model number of your tv?
I suggest you unplug the set for about 15 minutes and then plug it in and try again. Sounds like you may have had a power surge/bump in the middle of the night. Althoguh you are using a surge protector, doesn'r mean the devise hooked to it can't lock up during a power surge.( Surge Protectors are an insurance policy only, not a garrentee ). If unplugging the set and waiting doesn't fix it, it will need to have the power supply section of the board repaired. Good Luck
