Question about RCA F27443 27" TV
Have two of these monitors in the shop. One starts in about 10 mins, the other takes about 20. The start-up is in two stages: first, in maybe 5 to 10 mins the amber LEDS come on, then 10 to 15 mins later the video on input A shows up. Recapped the power supply in the long one; no help. In both, colorimetry, raster geometry is good once started. There are a gazillion caps on the A board. Once the boxes start and get warmed up, popping the on/off button brings the picture back quickly. Geez, I hate recapping!
The power supply is telling you that it has a short. I think you have a bad high voltage transformer in the horizontal deflection circuit. I've repaired several RCA's with this very same problem. The newer RCA's are vert prone to high voltage transformer failure ! Stargazer

These will run a bit hot, but make sure you have enough compound on it. If the old stuff was dry, use a solvent to remove it and replace the compound with plenty of new stuff.

once you remove the back cover from your TV, on the bottom left board there is a gray capacitor next to a vertical heat sink and it says KP 2000vdc this gets loose for lack of soldering after a while , remove the board turn it around and clean the area, apply flux and soldering put back on and your problem is fixed, let me know if this worked for you.

Does this tv have hdmi input and if so does the problem exist there?
If so I suspect the av input board could have a problem.
