32" Trinitron warms up picture goes black

Check its main power regulator section circuit for any loose solder terminals. Low power regulator voltage output is the problem to your TV.

Not likely to be cheap fix and it weighs a ton.

Yes.... u must adjust the screen voltage going to picture tube....located on the CRT module>>>little board connected directly to picture tube (take back off TV and you will see ) play around with screen control on the CRT module......can be adjusted at times to keep from losing picture!!! tube is bad...i know sure looks good when showing a picture....TRY adjusting screen voltage ( YES while TV is ON>>>CAREFULL ) gl

This could be a sign that the picture tube is starting to fail. To prove this try the following: Please note that there are potentially dangerous high voltages present inside the set, so be careful.

Unplug the set and remove the back. Locate the flyback transformer (lower right when facing the back of the set and has a lare red wire coming out the top.) There should be 2 controls on that part. One should be labeled screen the other focus. Turn the screen control slightly clockwise. Turn on the set. If the blanking stops, then this will "fix" the problem for a short period. This is not a final fix, but a short tern remedy to give you time to locate a replacement set.

If the above does not resolve the problem, please update this and we'll investigate further.

This problem usually lies on the horizontal output transistor, try to check also for shorted diode. you can buy ftom any electronic parts dealer or radio shacks stores

when the lights flash those are codes that tv repair men have.youd be better off buuying a new tv,they are less than 500.00 nowadays

Hi, tubes getting tired, band-aid fix you can do is remove back of set and turn up(clockwise) the screen control( small black plastic control mounted on side of flyback transformer, do not turn the knob marked focus) until you see a whole bunch of white lines across the screen, then turn same control counter-clockwise until all the lines go away, try several different channels to be sure all the retrace lines are gone, you`ll get up to 1 year more use out of it, than she`s done, good luck, BMW Rider

This is a simple and common problem. The solder joints on the vertical output IC have cracked loose. I actually did a housecall on the exact same set with the exact same symptoms this morning! A good tech will resolder the pins of the vertical output IC and all other major solder joints on the main board and the set will play fine.
