Thumbs up RCA F38310 with sizzle crackle and no picture

Someone gave me an old RCA F38310 that I really enjoyed using for several months but one day it decided not to work anymore.
You can hear it turn on and the little green power light comes on but there is no picture and just a sizzle crackle sound coming from the back of the set.
I haven't opened it up yet but I was hoping to find a service manual or possibly someone who has repaired one of these with this problem before.

If the problematic caps and diodes on the DM1 haven't failed previously and been replaced/upgraded, that could the problem.

Plenty of info on AVS (and numerous forums) since 2002. Just search around.

I found this quote from you. Is this everything that usually needs replacing?

Here's another excerpt:We use the RCA stuff, caps are part# 248988, diodes are #234048.
You will need two of each, the parts retail for about $6.00-$7.00 each from RCA
Generics could be cheaper, but I have never cross-referenced the parts since we always use the originals.
Tell the Sears guy to go ahead and order the parts under warranty, and change C14113/14115 also CR14107 and the one next to it CR14117.


I'm not an expert as to the how the colors relate to the ratings, but it seems that he's on the right track. IMO... just to be safe, on the next service call, I'd have all four components replaced and start 'fresh'. Just to be safe.

Only if it is related to your issue.
Good luck.

Let me rephrase that.
You mentioned "problematic caps and diodes on the DM1"
Are the caps and diodes mentioned in your quote all of the caps and diodes that are generally considered problematic or are there additional ones that are generally considered problematic that are not mentioned in your quote?

Yes. It's all you need for the "DM1 related issues".

But allow me to be specific. I'm am NOT saying that your problem is definetly due to the "cap/diode" issues discussed over the past 13+ years.

Replace 'em and see it if works.
You have a 50/50 shot.
