Hi Bryant,
Constant clicking means the power on sequence is not getting complete. Mostly it is due to problem in power supply board. I have replaced the main board also for this fault in a Samsung 46'' led.

    Thank you for that information and also how much would it cost to replace that part

    Hi Bryant, Since I am not aware of the costs of parts and the service charges in your area, only your local technician will be able to tell you about it.

SOURCE: When powered on the tv makes a constant clicking sound

THe clicking noise is the relay on the PSB that allows AC to be sent to the psb. It won't hold in due to some fault either in a resetable link or some other safety component. To check this unplug the cord from the mains for an hour, then try again. You should hear the relay click once and then the TV will power on for a short period before powering off again. The solution is to replace the component, other than that replace the psb. I can't get a manual to prove this so I am just making an intelligent guess until I can prove it.

SOURCE: green/ red pixels on screen. tv making annoying

If the unit has not previously had the PSU or Y-SUS boards replaced prior to this issue. Then it sounds like the voltages are off on one of those two boards. There is a process for checking those voltages and trying to adjust them. If those boards were recently replaced I would say the tech did not check voltage accuracy. But if it just happened out of no where go with the Y-SUS board as the problem. I say that because the unit powers on.

SOURCE: My Philips 50PFP5332D 50 in makes this clicking

its the capacitor inside the tv open it up and you should see atleast 1 capacitor which has bulged ( looks like glue coming out of it ) usually a 3000 ~ you can replace these yourself no problem for around 10p each but i do warn you there is a chance you could lose your built in freeview in doing so!

Proscan tv. blue indicator light is on no pic and no sound. can not turn tv off.


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory ResetF (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

I replaced the power supply unit on my 50" ProScan flat screen and now it wont even turn on just a clicking sound when you hit the power button.


The replacement power supply could have been installed incorrectly or may have been defective as received.

I've recently ordered a Proscan PLED5529A 55" 1080p 120Hz LED HDTV, However, a Proscan PLED5529A-B 55" 1080p 120Hz LED HDTV was sent. What is the difference? One difference i've noticed in the...


Same issue here. I'm debating to send it back as most specs are pointing to the A-B model as being 60Hz. I can't really tell of it's pushing 120 or 60 (ignoring the fact that the screen says 60Hz.) It almost "feels" like it's 120 but can't say for sure. Can anyone please confirm that the "A-B" version is indeed 120 or not? Thanks!

Proscan 40lc45s won't stay on


Try changing the input device to something you are sure, works such as a DVD player. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

When i try to turn the tv on it does it just clicks over and over


Hello,

Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your TV and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps

When I plug in my tv it makes a clicking sound like it wants to turn on but it can't. After i plug it in it won't turn on after I press the power button


Sounds like a deffinate power supply issue, if you open the TV, there is likely a bulging capacitor on the power supply. Even if not a obvious capacitor problem, the Power board is likely the culprit.

Can buy new one on many websites, or used on ebay.
make sure you buy based on the part # listed on the board, and not by the model number of your TV, as there are usually many sub-models that all have different interior parts, and most are not capatable with eachother.

It won't turn on and is making a ticking sound like when you turn it off or on constantly unless you un plug the power cord........What can I do to fix the problem?


you have bad capacitors in the power supply- look for the one with the tops bulged out.
Radio Shack has the caps or buy on Amazon.

I can't confirm if this works at this moment since I don't have access to my TV.
