Sony PVM-9041Q Trinitron: PSU, Trim Pots & Deflection

New arrival! Sony PVM-9041Q in a flight case. Giving it a quick test, the tube looks nice. Playing some #Castlevania just to quickly assess it. This one came with batteries on the back but wouldn't power on with them. I assume they are very flat. #RETROGAMING #CRT #Sega

(1/2) Early evening and I decided to do some maintenance on my recently acquired Sony PVM-9041Q. Switched out the colour trimmer pots and replaced the caps on the PSU. Fishy smell when desoldering the big cap. Used the ultrasonic cleaner on PSU PCB. #PVM #CRT #repair #restoration

(2/2) Testing the work with some homebrew. Namely, the R-Type port demo. Here are some scanlines for your viewing pleasure. #RETROGAMING #SegaGenesis #MegaDrive #rtype #SGDK #homebrew

(1/4) On the bench today, not one but two lovely 9" Sony PVMs (9045QD and 9041Q). PSUs already recapped, so today is deflection day. Don't skip deflection day! First up, marking the usual suspects. #RETROGAMING #CRT #Sony #restoration

(2/4) Removed the marked caps and applied some white vinegar in the areas just to make sure any electrolyte leakage is addressed. Then I clean up with isopropyl alcohol, before proceeding with the recap. Should be easy, only 19 caps on each board.

(3/4) Lol! Who am I kidding? We all know the solder on the back of these things is turning to dust, so a fairly quick job turns into a "reflow all the things" epic.

(4/4) There we go all capacitors installed and marked with a dot. All joints on the back looking shiny and new. Now the question is... But do they work? Stay tuned, to find out. 😄 For now, other matters beckon but I will be back with some killer retro gaming screenshots. 🫡

(1/2) Thanks to @PigsyRetro here are some screenshots of the PVMs running Castlevania Symphony of the Night on the Mega Drive, after the deflection board recap. First up the 9045QD (450TVL). #RETROGAMING #Sony #Castlevania #SOTN #MegaDrive #Genesis #restoration

Next up the 9041Q (250TVL). Hopefully, Twitter won't compress the photos so much that you guys can't enjoy. I meant to have both monitors running at the same time but I didn't want to faff about looking for my Extron, while my SO is trying to put our kid to sleep, she's sick. 😞
