I saw this tv advertised cheap in local website not working as the person said they
were watching it one night when it gave “pop” sound and it stopped working. No
red standby light at all.
It is approximately 7 years old so I thought I will buy it as possibly it is fault with SMPS
an it can be saved. When I opened and inspected visually for faults, I saw IC 7905 exposed
with no covering. I began to test the surrounding components for faults also and R7914 was
also open circuit.
I also heard some “rattling” sound whenever I moved the SMPS around and when I traced
the sound it was coming from the main 450v filter capacitors. When I looked there I could
not believe what I saw…..the body of a small dead lizard approximately one inch long !
It was under the shielding next to the capacitors…..Incredible !
How this got inside the tv is a big mystery !…..I have replaced the faulty IC which I ordered
from eBay and also replaced the resistor and the tv is now back to life…….
I did not take picture of the damaged components but have provided a web link here
showing the exact same SMPS as the one I dealt with. Just thought I let you know
Jestine how your knowledge from your books lets me know how to test components
correctly and minimise the costs I need to spend to repair !
Thanks again Jestine for sharing your knowledge with us less gifted in this subject !
