Samsung HL-T5076S DLP TV Restart Loop
I have an ancient Samsung HL-T5076S 50" DLP TV which has been working perfectly until recently. In the last month, it has begun to randomly have a restart loop during playback of anything. Tried plugging into different outlet with same result. Did some research on the internet and came to the conclusion it might be failed capacitors in the power supply unit. So I opened the TV and saw that the 22uF 250V capacitor was bulging with brown residue on the top - obviously bad. I bought a replacement Nichicon capacitor with the same 22uF 250V specs and replaced the cap. Also did a thorough cleaning of the unit top to bottom as there was quite a bit of dust buildup throughout. Replacement was quick and easy but I'm still having the same problem - random reboot, no different than before cap replacement. The rest of the caps on the power supply board look fine - no bulging or residue. Any idea what I should try next? Should I go ahead and replace the rest of the capacitors and see if that works? Or is it possibly something else?
Edit: also want to add that just before it restarts randomly, the screen goes to a bit of a yellowish tint and then to black as it restart.
Edit 2: Add images of the original capacitor
Edit 3: Add video off TV shutting off with back open - does this about every 2 minutes or so now
Edit 4: Add board images

@dlp2022 Where did you get the new capacitors? Do you have an ESR meter?
