25GT270 TV turned off by itself and never came back on.

Check its vertical output section circuit for damaged component/s. Check the vertical output IC.

most do there were installed in tv's in the early 80s and all tvs made after 1992 were fitted with r.c.a input video and audio

hope this helps

you must use the "Composite" video output (the single yellow plug, with the red/white for audio of course) of the DVD player. Tube TVs rarely have "Component" connections because they are primarily used for 480P and above resolutions, which tubers can't produce. If your TV and DVD player have "S-Video" connections, use them for the best possible picture.

New remote for ya:) ... dont forget to rate me plz :)

Considering the age of that GE model I would suspect the CRT is showing signs of weakening. Time to replace the TV...

Hi

did you see the standby light? in this case you said 5 to 45min. before the unit turn back on, this needs to check the oscillation circuit or the starting capacitor in the Hot area...

Thanks...

you may have a yellow, red and white input on your tv.A 3 wire cable goes from your video game (red, yellow, white outputs) to these inputs.If you do not have these , it will not work.

go into the tv menu and see if all the other channels have been set to off, if so turn them back on.

ticking sound (like a Watch) coming from around the Flyback Transformer but I don't see a spark is called EHT voltage . if eht voltage is ok 1 check filament is glowing or not if it is ok check voltages on crt. 2 if it is ok check luminance section in chroma section. if filament is not glowing check for low eht due to hor section check power supply output also. good luck

Could it be in the HV circuit? first you isolate h/output section from power supply. make power supply output ok. check h/output section for short circuit 1 print short near eht 2 diodes or cap.near eht 3 yoke H winding just by removing connector 4 EHT transformer regards
