Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Should I fix my TV or buy anew one?


Before you buy a new TV go through all the TV menu options to see if it has automatic dimming depending on the amount of light in the room. If it does it may be malfunctioning and turning that feature off may fix the problem.

Dash lights come on with the headlights then shut off


Do you have a dimmer for interior lamps? Like a rheostat, a little wheel that you turn up or down to brighten or dim interior lamps. Usually the instrument cluster lamps brighten and dim the same way.
Can you brighten and dim the other interior lamps?

I have a Samsung 55in curved TV. It has auto dimming. In the evening with the lights out it dims to where it is difficult to see the picture. Can I get rid of the auto dimming?


If the brightness on your TV changes automatically (randomly dims and brightens), you may need to adjust the:
  • Eco Sensor function.
  • - And / Or -
    • Energy Saving function.
    The Eco Sensor and Energy Saving functions adjust the brightness of the TV to reduce power consumption.
    • When you set the Energy Saving function to Auto, the TV changes its brightness automatically depending on what you are watching on the TV.
    • When you set the Eco Sensor to On, the TV changes its brightness automatically depending on the brightness of the room.

Hello. I have a Mitsubishi WD-65732. We are experiencing TV shutdowns about once every two weeks. Also, unless it it my imagination, the picture seems to dim/brighten depending upon other things on...


Hi,
I've suspect that your bulb has near to its end thats why you've encountered the subsequent shutdown and picture problem. This is the very common symptom of a faulty bulb. But since you've still watching your tv, this is not totally defective. I've advice you to look for a qualified technician to check the condition of the bulb before replacing with new one.
Hope it may help you.
Have a nice day.
Thanks for using Fixya.
