SOURCE: TV will not power up

LoL!!! I don't know why but all RCA's have Flyback Transformer problems! I have one to here is the part number 259296 if you look around you can buy it for about 15.00 if you know how to solder you can do it your self and save big time! Hey I'm doing it! I don't see paying $500.00 to fix it you could buy a new one. And they are just ripping people off because the parts aren't really that high to fix the flashing light problem. And the part is never on back order so your getting screwed they are probably wanting you to finally say just throw it away. And than they'll fix it for $15.00 and sell it for $600.00 Anyways for the people that are having the same problem go here to buy the Flyback Transformer for the D52W20 http://www.electronix.com/catalog/advanced_search_result.php?ELECTRONIX_CATALOG_SESSID=c5d90cbb7ae2d4c1449ea48542eef46a&keywords=259296&x=4&y=14

Also here is another website if you have access to junk TV's and want to know what other RCA Flyback Transformer will work. The price on this site is higher for there's though

Projection TV makers charge an arm and a leg for their replacement lamps. They make it easy to do but as a result the custom lamp assy is expensive. The trick is to just buy the bulb for your model TV from any number of us aftermarket sources at a fraction of the lamp price (less than $200) and install it in the old lamp yourself. really easy.

SOURCE: POWER WONT STAY ON

You have bad Capacitors cp150 2200uf 16v, cp111 330uf 35v cp114 220uf 35v this is common with these sets they are on your deflection board green with gold writing 2200uf etc. Look at capacitor cp150 if it has a bubble look on top it is bad so replace all 3 caps.

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to.

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.

The blue light merely indicates that power is getting to your TV. It has internal power supply problems.

ctgarden girl, my set does the EXACT same thing! I too wondered if a cold room was an issue. The set is only 4 years old, and I didn't have this problem in my old place where the room was a lot warmer.

Can someone please help?!?!?!?

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.
