HelloThere are two possibilites for this fault. The first one is shorted inverter transformer in the backlight inverter board. The second one is the fault with main board. For both faults, card base replacement is only possible. Check out which board has the short, and replace it.Image of the digital board is given here. Baclight inverter board can be located aty the panel itself, will be fitted vertically at the right or left side of it.

Hi sglassgold,

Here are steps that may help you fixing the problem. You should prepare tools and multimeter.

I'm assuming that your unit is dead set and your outlet is live.1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I've advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts on the power supply, you may visit the linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

4.If you see that the fuse is intact on the board, don't attempt to touch anything because there somefatal components stored electricity enough to hurt you with a simple mistake only.

The next steps should be done by an expert or qualified technician because isolating the problem on the power supply is technical and complicated. I would advice also to replace the entire power supply for your convenience if finding technician there is not possible.

Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

It goes into shut down can be caused by short circuits (in the power supply or in the backlight inverter), falied power supply module.
You need to do in-depth troubleshooting to locate the problem.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Its a power transistor not a voltage regulator. Do you see anything like SPA or SPB before that? Ex: SPA07N60C3
You can find the datasheets for that series here

Hi,
This could probably means that the power relay is working, though there could be bad contacts.

Since the fuse doesn't blow, now you need to check for:

Other blown fuses - occasionally there are more than one in a TV.

Replace with one of exactly the same ratings.

Open fusable resistors. These sometimes blow at the same time or in place of the fuses. They are usually low values like 2 ohms and are in big rectangular ceramic power resistor cases or smaller blue or gray colored cylindrical power resistors. They are supposed to protect expensive parts like the HOT but often blow at the same time.

If any of these are bad, they will need to be replaced with flameproof resistors of the same ratings (though you can substitute an ordinary resistor for testing purposes). Before applying power, check: Rectifier diodes, horizontal output transistor, regulator pass or chopper transistor (if present), and main filter capacitor for shorts.

An initial test with an ohmmeter can be done while in-circuit. The resistance across each diode and the collector to emitter of the transistors should be relatively high - a few hundred ohms at lest - in at least one direction (in-circuit). If there is a question, unsolder one side of each diode and check - should be in the Megaohms or higher in one direction. Removed from the circuit, the collector-emitter resistance should be very high in one direction at least. Depending on the type, the base-emitter resistance may be high in one direction or around 50 ohms. If any reading on a semiconductor device is under 10 ohms - then the device most likely bad. Assuming that you do not have a schematic, you should be able to locate the rectifiers near where the line cord is connected and trace the circuit. The transistors will be either in a TO3 large metal can or a TOP3 plastic package - on heat sinks. The filter capacitor should eventually measure high in one direction (it will take a while to charge from your ohmmeter). It could still be failing at full voltage, however.

If you find one bad part, still check everything else as more than one part may fail and just replacing one may cause it to fail again.

Assuming everything here checks out, clip a voltmeter set on its 500 V scale or higher across the horizontal output transistor and turn the power on. Warning - never measure this point if the horizontal deflection is operating. it is ok now since the set is dead. If the voltage here is 100-150, then there is a problem in the drive to the horizontal output circuit. If it is low or 0, then there are still problems in the power supply or with the winding on the flyback transformer.

Other possible problems: bad hybrid voltage regulator, bad startup circuit, bad standby power supply (dried up filter capacitor, etc.) bad relay contacts as mentioned above. However, these probably would not have blown the fuse in the first place so are less likely.
Good luck...

If the fuse blows again after replacing it, there's a shorted diode, bridge rectifier, capacitor or transistor in the power supply.

It sounds like there may be an issue with the power supply or internal components of your Proscan PLDED5030A-RK TV. The blinking blue light and popping sound could indicate a malfunction that is preventing the TV from turning on properly.

Here are a few steps you can try to troubleshoot the issue:

1. Unplug the TV from the power outlet and leave it unplugged for at least 10-15 minutes. This can help reset the internal components of the TV.

2. Check the power cord and connections to ensure they are secure and not damaged. If there are any visible signs of damage, such as frayed wires, replace the power cord.

3. Try plugging the TV into a different power outlet to see if the issue persists. This can help determine if the problem is with the power source.

4. If the issue continues, it may be necessary to contact a professional technician or the manufacturer for further assistance. They can diagnose the problem and recommend the appropriate repairs.

It's important to exercise caution when dealing with electronic devices, especially when there are signs of malfunction such as unusual sounds or lights. If you are unsure or uncomfortable with troubleshooting the issue yourself, it's best to seek help from a qualified professional.

Download the manual from PROSCAN 55? UHD LED TV ' Proscan (proscanvideo.com) and see section 13 (Troubleshooting Guide).

If it was my TV I'd recycle it then buy a name brand set, Proscan sets are plagued with issues.

If it is a copy remote for the Proscan Model you have, it should work when you insert the batteries. If it is a Universal Remote, you need to put the Proscan Code into it.

Question edited for clarity. You can't. Just buy a replacement remote! https://www.google.com/search?q=proscan+sound+bar+psa3713-c+replacement+remote+control ..

There is some troubleshooting in the link, but it is a budget unit that sells for around $90. If it has outlived its warranty, you just replace it. If it is within warranty, claim on it. They aren't really repairable. https://www.google.com/search?q=proscan+elite+tablet+and+dvd+combo+no+picture+only+sound ..

It is a standard Android Hard Reset. You will get an option to backup your data. https://www.google.com/search?q=proscan+elite+peltdv1029+factory+reset

The Proscan PLED5544U is a 55-inch LED TV. While it doesn't have a physical reset button, there are a few ways you can reset it:

No MODEL details and one of my favourite manual sites says they have 400 Proscan manuals. They ALL have basic controls for On/Off, Volume UP and Down and Channel Up and down. Get behind and at the sides the television and your will see them. This model has them on the right edge. https://www.manualslib.com/manual/484183/Proscan-42lb45q.html?page=9#manual also read this.
