TV was given to me by a friend after it would no longer power up. Ive tried replacing the 4amp fuse several times now, but when you plug the cord into the wall the fuse blows instantly. (slow-blow or fast acting)
fuse blowes as soon as pluged in to wall. manual switch nor remote will turn on tv. electrical storm night before, and now will the cost to repair cost more than it is worth? TV purchased at Wal-Mart 18 months ago or close. SN: V24610741 Mode.: iwt3206 built in June 2006

You have a direct short in the power supply or the high voltage stage, without more data it is hard to be more precise. But let us speculate, if the fuse blows right away, "power supply issues" If the fuse takes several seconds it is more than likely, " flyback problems "
On some models the reset is unplugging for a minute or two and plugging back up. Otherwise you have a blown fuse where the power goes in. If you decide to replace the fuse do no go over 5 amps. If the replacement fuse blows there is a short in the set and needs a repairman.
The fact the set blows up the correct fuse is because it has a short ahead in the circuit,it could be one of the diodes(4) that is shorted,if one of these guys is bad all of them should be replaced with the exact replacement,ahead of them it should be a regulator and he is bad (shorted) it could have taken the diodes and the main fuse.The cause might have been a power surge.If you are familiar with tv service you can check the regulator and the diodes before you put in a new fuse,if you are not too familiar be safe and take the set for an estimate.If you suspect power surge or lighting damage it might not be worth repairing.Let Us know if you need more information.
A 10 year old RCa most likly has a bad Horizontal output transistor as well as the main High Voltage transformer and The transformer is no lonmger available from RCA. The replacement wont last longer then a year if your lucky. My advice on a set this old ?? Buy a newer one!!
First, unplug the tv set for 30 seconds, plug back in and try ti turn on..
Second, If you're NOT still under warranty you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace.
Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs.
You can also check the board where the components are mounted and resoled any that look bad. Brief power outages may cause the TV not to turn on. If you are using a surge protector, try connecting the set directly to the wall outlet.
In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer.
All can be replaced at a local electronic or hardware store and they're easy to replace
If this does not correct the problem, you may need to have your TV serviced.
