RCA P56830BL 56"... | Answered on Mar 16, 2012


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. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.

All these can be checked on the power supply board.

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.

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.

ok, you asked, ON THE BACK OF THE SET IS THE CHASSIS NUMBER PTK195?

All RCA/GE sets have a chassis number on the back.

I am available of course for paid questions. Is it 195 chassis or not?

That set is a 1994 model set. You have 3 picture tubes in that set of which are no longer available or made anymore.

Most of the service information for this and the sets that were made in that model year was on microfiche. Unfortunately I do not know if it even available anymore. RCA that made that is is not the same company today. You may want to call Washington Electronics at 703-533-9595.
They were a authorised service facility for RCA but has gone out of business recently. Hopefully they have not disposed of the microfiche they had.
I hope this helps,

Try switching the external/internal speaker switch on the back of the tv to internal. This way you should at least get sound (from the TV not the sound system) when you change the volume of the TV itself.
Explain your set up if you need more help. By that I mean what do you have hooked to the TV and sound system, Satellite or digital cable box DVD ?
Make a note of where all the inputs to the sound system come from.

sounds like a vertical and horizontal deflection issue..maybe your control board is unhappy.
you inclined to do this work yourself?

Sounds like you have a bad screen asy,this is located under the plastic were the tubes come up thru the plastic,its in the right top corner and has 6 turn controls on it,part number is 204809,this part must be generic,the part has been discontinued by Thomson.

Most of the screen cover for sets older than 8 years have been discontinued,get the size of your screen leaving about 1/8 of and inch around the screen,you can get your local lumber or hardware store to cut pexie glass to fit,get velcro and apply to sides of screen to attach glass,make sure to sand any sharp sides before attaching.
