My tv won't turn on

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.

Toshiba Regza 37in - 37HL17
TV will not turn on - Yellow power ind. Light blinks three times...
Fixed with a firmware update (hard to believe, but true). Search Google for a file named: 2007SEN069.zip (don't worry if the page you find it on doesn't mention the 37HL17 - it worked fine). Unzip the file, and copy the 3 folders and 3 files to the root of a small SD card. The SD card MUST be 2GB or less in size (I used a 1GB card), and it MUST be formatted with FAT-16 (not FAT-32). Mine was pre-formatted as FAT (FAT-16). The SD port is on the back of the TV behind a cover plate near the power cable. You do NOT need to remove the back cover of the TV, just the small cover plate (1 screw). UNPLUG the TV; remove the cover plate; insert the SD card (prepped as explained above); Plug in the TV; Watch the yellow lights blink, then turn blue, then go dark; UNPLUG the TV; remove the SD Card and replace the cover; Plug in the TV; Yellow lights will blink a few times (this is normal); when blinking stops, turn on the TV and you should be good to go. :-)
Pictures attached are from a Toshiba software upgrade bulletin I found online.

My TV surname off after 5-15 minutes of use. The red light in the front blinks once every 3 seconds continuously. If I hold the power button down on the tv, it will turn on and do the same thing.

Replace the defective electrolytic caps on the power supply and/or replace power supply, check at www.partstore.com That should fix your problem.
