SYMPTOMS: Having difficulty powering on at first, and issue worsened (power up time was slower, TV would sometimes shut itself off, multiple power attempts required, etc.) until the set went completely dead.
DIAGNOSIS: In cases like these, it seems as though the TV doesn't get enough power. Essentially, that is correct. The issue here is a common one. Bad capacitors. In these Olevia sets, there are a few capacitors that usually go out. You will be able to tell if they are bad by the trademark bulge on top.
SOLUTION: Acquired the correct values of capacitors and replaced the bad ones on the PSU. Keep in mind I normally go up a voltage rating (i.e. old cap is a 1000uF 16V; replace with a 1000uF 25V). Here's the capacitors you may or may not need:
- 1000uF 50V and 25V (up from 35V/16V)
- 680uF 25V (up from 16V)
- 1500uF 25V (up from 16V)
If you have questions on repairing one of these models with the same issue, take some good pictures of the PSU and contact me. I'll help you out if I can!
