Any piece of equipment that has suffered from electrical storms can be a major problem You could be lucky & it might have just blown an internal fuse or protection resistor or it may have destroyed several components in the power supply. I would advise calling a repair centre to have someone assess the damage & give you an idea of what is needed to repair it. Best of luck.
The television has a protection circuit. Sound like you know something about electronics so that is cool.
I suspect the HOT or High Voltage Transformer. If you want to operate on it, they typically will short externally from moisture or plastic high voltage breakdown. The TV starts, shorts as it cannot come to full high voltage, then shuts down. If your brave, you can unsolder the HOT which is the part that is on the main board or that comes from the top of the picture tube wire into a dark or spaceship type object.look underneath, sometimes they short underneath and you can scrap the carbon and get it to at least start up and work. Do not leave this as a fix as it can be a fire hazard.
The HOT is the most common. They are around 20-60 bucks. 34" TV. I am assuming this one without looking it up it is NOT a flat screen, as most do not squeal like that nor do they have to de-gausse like the old ones. I just looked it up and yes it is not a flat screen. Old school, so that is more thank likely the problem.
you have damage your tv micro chip, regulator ,or horizontal output with static current when you plug out your tv from th plug,what is clicking is the relay trying to power up your tyv but due too the damage it cannot power have a tech repair your tv good luck
This is a typical condition if the power supply has failed or a power-consuming circuit the supply services has exceeded a predetermined current draw. The relay you hear is preventing further damage or even fire. You will need local tech help with this.
Yes, it's quite possible that you indeed may have sufferd from a Power Spike, induced by lightning during the storm, esspecially if plugged in during said storm. I have had quite a few customers ova the years with this exact problem. I always advise my clients to unplug ALL devices during a storm, and for ones that simply cannot be unplugged then some sort of Spike/Surge Protection device MUST be used. As a matter of interest, I have written many a report to insurance companies to support a claim for a replacement.
The fact that its clicking on and off tells me that theres probably a short in the horizontal sweep/output circuit of the set. You see when the set starts up the power supply detects a large current surge and shuts down. Some sets will try three times if this happens and then stop till the power is pressed again. It sounds like this set dosent have that way of operation. Its going to need a technician to look and troubleshoot the problem Good Luck
