I loved my 21" Trimitron when playing games on my computer! That thing is huge and heavy!Comment

Re: Sony Trinitron recap -stay tuned-
Exactly, a lot of caps!
I'll do the chassis only, not the vertical boards.
And to be honest, I'll leave the big original elco at the primary.
All others will be new.
That sound crazy but it's for a friend.
Two nichicon PL have eaten 4 square centimeter of copper!
I told my friend: "You're silly! To reduce a pcb in that condition they must been leaking and smoking since a couple of month! What you're waiting for?
-stay tuned- elcos will arrive on July 1st.Comment

Re: Sony Trinitron recap -stay tuned-
It's a good idea . You won't have to worry about re-soldering , because these were some tin to envy .
I threw one huge AR 25 Last week , probably from laziness . But i kept the boards for useful parts , as usual ..And eventually , i found also the faulty parts . It was moisture destroying the vertical Audio system .Comment

Re: Sony Trinitron recap -stay tuned-
System is now operative but I need the manual because it need G2 adjustment.
Never done on Trinitron so I need to read before destroying all the work done till now.
The chassis needed FULL RESOLD, the vertical boards needed PARTIAL RESOLD,
the CRT pcb needed FULL RESOLD, the small PCB that link chassis to speaker needed FULL RESOLD.
So: a lot of Sn-Pb (100-150g), a lot of caps, 4*4 square cm routes destroyed by acid (nichicon PL = bye bye copper )
If it is NOT YOUR TV, don't do it!
A lot of time, a lot of components, a lot of Sn-Pb (100-150g)
Stay tuned.Comment

Please when making such an interesting thread attach the pictures.
We hate it when they disappear when the host has a problem.
I resized & attached the ones in your previous post..."The one who says it cannot be done should never interrupt the one who is doing it."Comment

A couple of days ago I finally got my hands on a locally sourced Trinitron and after lugging all 175 LBS home I gave it a good cleaning inside and out. The guy said it had been in a shed for 2 years, but the outside wasn't too bad. The inside was another story and while there was no evidence of mouse, it had certainly been kept in a VERY dirty home.
I cleaned it to an acceptable level of grime, at least clean enough to where nothing would heat up from the dust insulation. I then tried it out and it worked!
I'd say I had it on for about 15 minutes or so and then lugged... -
Hi everyone, I've been troubleshooting my 20" Sony Trinitron (KV-20FV12) CRT after it failed to show a picture. The standby LED is blinking 4 times, which according to the service manual is a failed vertical deflection via the self-diagnostic check during power up.
After getting the TV checked out by a technician and doing research on my own. The most obvious first step was to replace the IC502. I've done so with an exact NOS replacement with no luck. I've read a few suggestions to make sure the 12V supply to pin 2, but that voltage check would seem misleading? It seems if the... -

This is a CRT I sold a few months ago and it's came back with this weird issue. It's intermittent, but not a thermal fault, or tap sensitive - just completely random. The right side of the picture completely blanks out (picture is not shifted). The on screen display is unaffected though, so not a fault in the line section. Anyone seen anything like before in a CRT?
