I got this TV for free from a friend of mine and he told me it doesn't work since it had been struck by lightning. He also said it was repairable, and rather than paying $100+ to have someone fix it, I was wondering if there were any ways I could fix it myself?
Probably just a blown fuse.
You can go to www.samswebsite.com and download Photofact #4918 for this set to get the schematic and troubleshooting tips for $20. Since the relay is not picking up, the fault is probably in the standby power supply and thus you would not be getting any power to the rectifier bridge to begin with. I do not see to many Sanyos and therefore my tech library on that brand is limited and I can't provide more spscific advice.

Re: TV Doesn't Work
How do you know expert if the relays getting any power? I work on alot of sanyo and NEVER had one with just a blown fuse when hit by lightning! As a matter of fact NONE of the many many sets I fixed in the lighning capital ever had just a blown fuse. First off this person has no know how to work on TV sets or they wouldnt be asking,second A TV set is no place to be experimenting inside of. and third you must know basic electronics and know how to use a mutimeter, check resistors, capacitors with a Good capacitor esr type meter, and use of an ocilisciope.. If the peep that owns the TV set has no training they should seek out a trained tech to assist them on this. After all would you work on a 140,000 volt main feeder on a tower if you had no clue what to do????

Either the tuner or the video IF stage circuit of your TV is faulty. Tuner has no repair, can be replaced as a unit. If the fault is with video IF stage, it can be repaired. But, both the work is skilled one. You must have through knowledge in electronics, and work experience to do this work.
yes it can be repaired,mostly tv strucked by lightning are dead set because of the very high voltage that goes to the circuit coming from the lightning.there are voltage protector on the circuit.they are placed on the high voltage section of the circuit example are,pico resistors,glass fuseand varistors..yuo need to check them out..
Best to take it to a repair centre as lightning damage can cause either minor fault such as an internal fuse blown or major problems that would make it uneconomical to repair. Ask for an estimate for the cost to repair.
It may be too late for this advice, but if you live in a lightning prone area, you should consider having a 'whole house surge protector' installed.
The cost should be well under $300 (a lot less if you install it) and with the included insurance (most often for $25,000) it is a good investment.
If your house was struck, I'm surprised you don't have a list of things that no longer work.
It could just be an expired TV.
depending on the intensity of the lightning strike.Your tv may have blown components in the power supply section of the motherboard.
unfortunately its very very difficult to acertain level of damage unless its looked at by a trained tech/engineer
Looks like the flyback (high voltage transformer and probably the majority of the power board is kaput. It would be cheaper and probably worth your while to invest in a new TV rather than try to fix this one..
If it was struck by lightning, the surge would completely fry the insides of your TV. Your TV probably won't work anymore and you may have to consider replacing it. Some TVs have accident warranties so something like this could be protected, but if not, you will have to purchase a new one.
Assuming this line is across the screen horizontally (side to side), this means the vertical deflection circuitry is dead. In late model sets, there is a Integrated circuit package which drives the vertical yoke coils. Possible defects: the I.C. itself, bad solder connections where it solders to the board, missing voltage source to this I.C. (often around +24 volts), or a bad electrolytic capacitor in the associated circuitry. This latter often results in a non-linear picture, or less than full deflection condition, rather than a thin line only.
It is possible lightning caused this problem, (I've seen some rather illogical damage from lightning ) perhaps it produced enough of a surge to pop the I.C. or a fusible resistor in that voltage source noted above.
