The model indicated here is rear projection that uses three picture tubes.
If rear cover is removed--can be done by removing entire front screen but there are hazards like damaging the screen---with rear cover removed clean the lens in the three round cyclinders which point up and are hard to miss===
They are the light source for the picture---there is if you look up inside and to the rear a mirror but unless grimy it rarely needs cleaning.
clean the lens with a lens cloth or even a paper towel with glass cleaner sprayed on the towel.
First, try setting all display settings to default or 'normal' or 'standard' and disable any picture processing functions. If your TV is LED backlit then the LED dimming function may not be working correctly (dimming is done by rapidly switching the LEDs on & off).
Hello! My pos just did this today after I got in a hot car (had windows up for security). Symptoms: Briefly displayed the PIONEER default splash screen, LED lighting was the default ... light/bright pink (to match pioneer?).
Then screen goes black, then backlight gets fully dimmed and LED dims to darks white (R,01G,01B01)
Wouldn't really respond to anything... but plays CD in background.
I had a brainstorm while sitting in my car at ACC (ignition) and reading the lame online TS guide. I turned my car to ON and put the gear shift in REVERSE.
The screen flashed to the password, and flashed black again....
Some how the system stablelized after some time and I resurrected it*.
* After tinkering I found ALL settings except the NAV data/settings had been lost. In addition I believe corruption has occured in the memory holding the voice data. TTS... that phone thing voice command wont display when i press down on the Multi-nav? dial. Also system crashes when I try to access language settings. Sometimes a Windows CE error message bled thru reporting a fatal application error. Illegal operation request...
Hope this helps. I think my POS is going back to cartoys before my 30days is up. Pity
that means you are drawing to much juice out of the battery you are going to fry your altinator if you keep doing that get a bigger battery or compassitor you can do seriouse damage to you car and system as well could blow trust me i have done it.
Likely you have a bad ground at the bulb socket! You can either clean it, add another ground wire, or both! Don't ground a power lead... Identify both running power and hi-beam power before making ground! You can use a test light to do this!
