Question about Akai PT5492S 54" Rear Projection Television
Worked fine for 5 years. Started getting slower coming on. Now will not
come on at all. Clicking noise heard coming from inside guts of tv.
Any ideas? Thanks.
These sets use what is called a "switch mode" power supply. In order for them to work there is a capacitor that "kick" starts the process. If that cap goes bad, the power supply will not start up. Also, there are other caps inside that maintain the oscillation required for the power supply to work. There are 2 options for you here.
1) Replace the entire power supply module.
2) Repair the existing one.
Sicne these types of power supplies are not the easies to diagnose or repair, I would suggest that you replace the power supply module. That should resolve the problem.
Please note that there are other causes of the reported problem, but hte power module becoming defective is the most common.
