I was wondering if a power supply in a t.v could be easily changed if it is found to be defective. Is there soldering which needs to be done or is it just plug the cable into the circuit board and go. It is a 7 year old 32" Magnavox television. I can see a flashing yellow light inside the back of the case when I plug it up which is possible a code for the problem. I just planning ahead since my computer went out the same time as my t.v and they were both plugged into the same surge protector. My mother board in my pc indicated that the power supply was bad so I am assuming the samething is wrong with the t.v as well.

No. Most TV sets have their power supply circuits integrated with the rest of the TV circuitry. So it's not modular like a PC power supply. It's not serviceable for consumers, and the best person to do the job is a technician adept on these matters. TV sets have high voltage circuits, so it's really a risk for you to get electrocuted if you don't know what you're doing. PCs are much easier to fix because most parts are modular, and all you need to do is to plug in upgrades and parts. TV sets area complete package, and most of the circuitry are on one big board, and it's difficult to figure really which components are parts of the power supply circuit unless you have a circuit diagram as a guide. Yes, you will most likely do soldering to change components.

No changing a power supply on a tv is NOT a plug in operation. It will in most cases involve soldering and de-soldering wires at the very least.

Not quite as easy, but doable. Some soldering may be needed depending of the make. Be careful....make sure you short the supply voltage to ground. (unplug first), or you may get a painful surprise. Also, it may be cheaper just to but a new TV.

TV's hold a very large electrical charge, that has to be discharged by a voltage discharger, I seen a TV repair friend touch the wrong thing with out discharging it, burnt his hand & threw him across a room, so do some research before you touch anything. good luck with that
