How do you replace the capacitors in a Sharp LC42D65U TV?

That error sequesnce is an internal voltage error and it could be the power supply or the main board. The power supply is usually the problem They are about 75 dollars and the place I use shows them out of stock. http://www.shopjimmy.com/sharp-rdenca298wjqz-power-supply.htm

A white screen is a bad display board. You're looking at a $300-$400 repair unless it's under warranty.

I have a Sony TV but if yours is a digital tv this should work . Go into the guide and select the program you want to be reminded of then a option should be available to remind you

The power supply board has some electrolytic capacitors that have gone bad. Put a new power supply board in it. You can get it here : TV Parts Universal TV Stands DLP Chips ShopJimmy

It is a indication the set is not going to come on---usually a standby power supply problem in the set.

U already change the remote control for brand new batteries wright?Yes.Remote controls devices are heavily depend on it CPU chip for all of it functions.Test the tv manual buttons like Power,Menu,Volume - + and Channel + - all work?Yes.The tv remote control CPU is dead that why doesn't read the tv infered laser signal at all.Try website like Remotes.com to buy an original remote for the replacement.

Hello,

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.

Good luck.
