Hi
Please go through this manual. http://www.retrevo.com/pdf/23615ci971/3/TV+STAND+INSTALLATION#q=Proscan+32LB45Q

Tries warranty service any how,they might fix it for u.Fix it ur self?Take the tv aparts.Tv have power supply board problems.That the board where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new reburbish power supply board for the replacement.

Hi,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.

All these can be checked on the power supply board.

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Regards.

There is nothing wrong with your TV. It is the quality and strength of signal of the channels. Sometimes due to atmospheric disturbances also, the transmission is affected.

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.
