Hitachi 65s500 dim

Good Day, CCooke;
Lamp Number for the 55V825 Model is; UX21516.
To replace LAMP remove Front Panel outwards until the quick snap disengages. There is small cover on the left hand side, using a philips screw driver; remove. Two more screws secure lamp, use handle to remove. ALWAYS, unplug TV from A/C power source first. Good Luck, big IRISH.

Good Day;
Try this:

Symptom: All Front LED indicators are flashing in sequence: Power-->Temp-->Lamp-->Power......continuously
Cause: Replace Lamp . This symptom may happen all the time or it may be intermittent. It is normal if it occurrs from time to time, See OG under TV Front Indicators explanation notes.
Good Luck, big IRISH.

Yes. You need to have a DVI connector on your PC for direct DVI-DVI connection or you can buy a DVI-VGA cables for around $25 bucks. Then, after connected, go into your display properties and adjust your settings. Hope that helped.

SOURCE: Picture intermittently goes dim.

How many hours on the lamp timer?  If 10,000 or more the lamp is approaching end of life and should be replaced.  Lamp will dim when approaching end of life rather than just go out.

Did you replace the lamp door? A flashing red light is an indication of a door open or an impropely seated lamp. Try removing the lamp and reseating it. Reinstall the door and try turning it on again. Also, you may want to unplug the TV from the power source, count to about 20 and then plug it back up again. This may reset the TV.
Good luck
