How does one remove the base of a Salton Model SU 08 Plastic Urn to relace a new power cord
To remove the base of a Salton Model SU 08 Plastic Urn to replace a new power cord, you can follow these steps:
  1. Unplug the urn from the electrical outlet and let it cool down if it was in use.
  2. Turn the urn upside down and locate the screws that secure the base to the urn. They are usually located at the bottom of the urn and may be covered by rubber feet or plastic caps.
  3. Remove the screws using a screwdriver.
  4. Carefully lift the base away from the urn. It may be held in place by clips or other mechanisms, so be gentle and patient.
  5. Once the base is removed, you should be able to access the wiring and the power cord.
  6. Remove the old power cord by detaching it from the wiring.
  7. Install the new power cord by attaching it to the wiring in the same way the old cord was attached.
  8. Reattach the base to the urn by aligning the clips or mechanisms and securing the screws.
  9. Flip the urn back over and plug it into an electrical outlet to test the new power cord.
Note: If you are not comfortable working with electrical components or unsure about the process, it is recommended that you consult a professional or contact the manufacturer for assistance.

Hi, I have a 50" Sanyo model DP50843. It started to make a high pitched squeal while watching, so I turned it off and I have been unable to turn it back on since. Tried unplugging it and plugging it back...
Sounds like you heard a capacitor fail. Check the fuse on the power supply board and look for puffed up electrolytic capacitors on the power supply board and all the other boards in the TV. You can get replacement boards here: TV Parts Universal TV Stands DLP Chips ShopJimmy

My onn tv won't turn on the stand by blue light just keeps flashing !!! Does this mean it has gone to tv heaven ???
Often it can be as simple as bad capacitors on the power supply board, or if you cant desolder and solder replaceing the power board will usually solve a blinking power light for certain LCD tvs depending on model number but I would need your model number to further assist for your paticular situation
