Question about RCA D61W20 61" Rear Projection Television

Follow up on "no power to my tv"

OK I changed the fuse at the power supply and the new one blew also. I am going to have to have it looked at by a pro, I know this, but I was wondering if anyone knew what it could be and about how much it would cost to get the job done, I would like to at least have an idea so I am not getting messed over when someone comes to look at it. ps. There was no lightning and the wall plug-in works fine Thanks for the help before on the previous question.

Let me give an idea ...after the fuse you have the bridge rectifiers and it can be all in one package or 4 individual diodes after that you have a big filter capacitor and then a power transistor called the switch mode regulator,this are major parts that can make the fuse blow up right away as soon as you plug the set in wall but these parts work along with about 30 other minor parts.If the fuse blew up at plug in it can be one of these but if it blew at turn on from the power botton it can go farther down the power supply,is hard to tell how much is damage and how much it will cost.Get an estimate and then decide.Good luck

TV blew fuse. Replaced with 125v 5 amp from a 33 inch Toshiba that has gone bad. The 5 amp also blew. Purchased new 4 amp fast blow fuse for unit, now nothing happens, i.e., no blown fuse, no circuit...

replacing the fuses with random values is prolly not a good thing...but one thing to check is a big transistor know as the HOT. This will more than likely be clipped or screwed to a heat sink NEAR the flyback (big transformer, has a wire going into the big glass tube). That causes fuses to blow...If this does not work, let me know.

We had a power surge in our living room while the TV was on. It was also plugged into a surge protector, however, everything else turned back on but the TV. There is no power going into it at all, as if...

Sounds like it might have blew a fuse on the AC input to the power supply, have to remove the back and look for a fuse near where the AC wires go from the plug on the tv. If the fuse is good
the power supply board will have to be checked or replaced..Next time consider buying a surge
protector that starts clamping at a lower voltage. Panamax brands usually start going to work
at 150v rms, where most others start at 330v rms..

My SW 22HT Kenwood subwoofer stopped working.The fuse was bad it was replaced and the new fuse blew again

The reason the fuse blew again is that an overload has occured. It could be a faulty part in either the power supply section, or the amp section. Follow the curcuit from the fuse, be on the look out for damaged, burnt parts, suspect anything on a heat sink.

Tv worked until I unplugged it and moved it, now it won't turn on.

Ok try connecting it to another plug see what happens if that does not work then more than likely your tv set blew the main fuse which is located on the power supply right where the power cord comes into your tv set, you can get that fuse in any electronic store and change it out yourself just be very careful,hope this helps thank you.

Will not turn on.

If the TV is blowing the fuse in your house, It looks like a component in the power supply is shorted.
To fix the TV, you will need to buy a new power supply module or get the one inside the TV fixed.
Good Luck.

Fuse location on tv

a fuse is a small glass tube about 3/4" to 1". it is located near the end of the power cord inside the tv. it is located in the power board supply circuit. there are several reason why fuse blew up. 1. sudden surge current/voltage in your area 2. shorted in either power supply or horizontal deflection circuits. when replacing fuse, be sure to change it with the same value. but if after replacement has been done and the fuse blew again, there is a short in the circuit as stated in reason no. 2. refer to a qualified service technician if you are not inclined with this job. good luck!
