SOURCE: TV WILL NOT START

You need to look at the power supply board for swollen capacitors. Some of the capacitors will have a black goo on them and that would be your problem and why it cannot start up. You can find the power supply board by removing the back cover, looking towards the top middle. Once you have located that, look for bad capacitors as stated above. If you are comfortable soldering, you can remove the bad ones and put in new ones. Look at digikey.com for the replacement capacitors. Simply put in the specs of the capacitors. Mine for example were 680 mfd at 50 v. I ordered 4 of those as my power supply had 4 capacitors with the black goo on them. After I put in the new parts, at a cost of $5, my tv stopped making the clicking sound and it turned right on. I tested the bad caps for giggle and they were not holding their power as they should, so they were confirmed bad. I hope this helps.

SOURCE: tv making clicking noise while I am watching

Hello everyone,

I bought the model TH-50PX60U June of 2007. I've been hearing the very annoying clicking noise as well.

Since the TV has a one year warranty, I just called Panasonic and they've scheduled a tech to come over and take a look at it three days from now.

I will publish the results on the same page.

SOURCE: Tv makes clicking noise but won't turn on

Definitely a power supply problem.I had the same problem and changed the power supply, and TV works normally. Depending where you buy the unit, it shouls cost around $150/--, and it is very easy to replace.

SOURCE: i have a sony 40 inches bravia flat screen hd and

Could be the decoder:

1. unplug the TV ans wait a few mins.
2. If you have digital cable box or dish tuner reboot those as well (likely your issue)

What you have is artifacting what that means is tiling garbiling and freezing this happends when the data in the digital stream just stopped hence Frozen.

Try those things rule out your cable tv box first or your sat box, if this is OTA over the air your antenna.

1. Try DVD's if it happends during a DVD you do have a decoder issue if it does not you need to talk to your cable tv or sat operator.

So you got 3 possiabilites here 1. the worse Decoder, 2 cable company or satalite provider, 3 your antenna is in the wroung position.

I sure this will help.

It could be a power supply problem. In this model at least 2 capacitors, go bad in the power supply I think they're 1000uf/10V. If you look at the power supply board you will notice a bad cap with a blister on the top. The whole power board is from $100 - $200. I fixed a lot of these sometime the Y or sustain board goes bad. Visual inspection then measuring voltages..
Best of luck

Clicking noises before TV turns on.


The clicking noise is coming from the power supply relay. Is makes this sound when the TV is usually turned on or off but has become faulty. It will only get worse over time usually until the TV will no longer turn on anymore. You need to replace the power supply in order to fix the TV.

The set has developed a short either in the power supply or the horizontal/high voltage circuit. The power supply makes a weird noise when it gets overloaded. This can get complicated so have a repair shop check it out for you. Thanks

Maytag Performa Bottom Freezer refrigerator making weird noises


This can be due to low supply voltage, causing the compressor thermal overload to trip out. Therefore when this happens the compressor gets hot and it keeps trying to start but fails. It can also be a faulty starter relay, which is located in the conncetion box of the compressor and is very simple to replace.

Loud popping noise


The 23" CRT set may have a high voltage breakdown in the flyback transformer or focus divider. Take the back off and operate the set in a dark room. Look for anything that has a blue glow around it or sparks flying when the pop occurs. I won't guarantee this will find your problem, but it is definitive if you see these!

I once had a set with these symptoms. I stopped the blue glow and arcing by covering the focus divider with epoxy. It worked for a couple of months before the divider literally broke apart.

Weird clicking noise and computer freezes.


Laptops have very few moving parts. Your problem is more than likely either a fan or your hard drive. Remove the hard drive, start the computer up and just let it run for awhile. If the clicking noise never comes up then thats your problem. If it does, its probably a fan.

Disregard anything on the screen itself, just let the PC run. It sounds like after the hard drive has been spinning for a minute a motor starts to die.
