Hello,
since you didn't get any picture, does the TV bring out sound? If the TV does not bring out sound, then it means the TV is having a power problem.
The clicking sound most of the time indicates a bulged capacitor on the power supply board of the TV. I think problem is with the power supply board and not the bulb.
But
more often bad capacitors causes problem on the power supply board. I
do not think the power board needs replacement, rather those defective
capacitors is causing this issue. Open unit up and take a look at the
power supply board.You will probably see one or more electrolytic filter
capacitors that are bulged up in the top-not perfectly flat like the
others.
The value of these capacitors will be different, most
likely they will be somewhere around-820 to 2200uF/25 V( or /10V
sometimes)
You can replace them with same values but I would
recommend the voltage rating to be higher(like 35V for an original 25V)
for reliability purposes.
What happens is,these bulged top
capacitors will cause a low and unfiltered DC voltage=main board will
malfunction(the relay will keep clicking until the caps are holding
enough charge to bring the voltage up over a threshold point).
You
can buy these capacitors at any Fry's or Radioshack store or you can
order them online at vendors like "mcmelectronics.com"(look for
electrolytic capacitors). After replacing these capacitor(capacitors)
most likely the normal operation will be restored. Or you can by a
refurbished complete power board to save you some stress from
www.shopjimmy.com.
Note: There may be also some other causes for
this symptom ,like a defective T con board ,or main board,but the bulged
top capacitors are the most common cause for this issue.
If you
don't know about TV repairers, take the TV to the nearest repairman to
fix the fault for you. Also, note that TV stores a lot of current, so
wait a while before opening the TV back cover.
I hope this helps.
Regards.
