Question about Sony Televison & Video
When your TV turn off, does it turn back on again if you try to turn it on again? Also, does it take time before it turns on?
First, check if the time of your TV is not turn on. If it is not a timer problem, then it is certainly a power problem.
The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.
I do not think it needs replacement, rather some defective capacitors are 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.
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.

common problem for these is bad capacitors in the power supply, Remove
the back from your Tv and look at the power supply on the left hand
You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heat sink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
This type of problem usually indicates that the power supply unit for your TV has become faulty.Either replace it or get it repaired.
Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
Hope this helps

I would recommend getting a Logitech Harmony remote. The benefit of this universal remote is that you can program macros to start all of your devices in whatever order you want them to turn on so you can have programs like "Watch DVD or Watch TV", the remote will switch your TV to the appropriate input and output channels.
The other good thing about this remote is that you can program buttons specific to your device. You simply plug this into your computer and type in your model number and it loads all of the codes automatically. The RTD155 is supported by the Harmony series.
