SOURCE: HDMI Port quit working

My first guess is to inspect the lead try the easiest solution first then approach the difficult after .
The second course is more painful if the lead is indeed ok then you are probably looking at one of three things constant plugging in and pulling out has caused microfractures on the pcb circuit isolating the HDMI plug ,Or dry joints on pcb , And failiure of input components on circuit . Sorry not to be the bearer of better tidings but this is one of those faults that make an engineer scream ?
WITH JOY £££$$$$££££ as it is going to take ages to find ?... Regards Vortash
Unless it is a common fault and is described in the engineers service notes lol.

How do you get rid of error 803?


As posted for a similar problem:

This is an issue with IC 803 on the Z board. This is a 3.3 V regulator that supplies this voltage to the slot card cage. Most input boards use this voltage EXCEPT the component board which is why it keeps playing along whike the DVI, HDMI, or composite signals will cut out after warm-up.

This is a surface mount multi-pin IC and is a bit tricky to replace.
The entire board is PN# TNPA3198xx with suffix determined by what model 7 series plasma you have.

This was a problem from around Nov. 2004 to Mar. 2005

There is a source lock and source button I would unlock source lock button and the push source button until you get to your hdmi input you are using. You also may just plug in one input first and once you get the input right play with the multiple hdmis

I just got a new Optoma HD20 and only after 1day of use it is not showing HDMI signal, although it is showing VGA signal. Why is this?


Hi miracles4all: I solved HDMI signal issue in my Optoma HD20. In my case it was the lack of contact between the HDMI cable plug male ending and the Optoma HD20 HDMI female port. My 35ft cable plug male HDMI ending was not completely "seating" in the Optoma HD20 HDMI female port. I solved the problem by purchasing a HDMI female to female coupler and adding a 3ft HDMI cable that had a slim male ending. This 3ft HDMI extension cable made better contact to the Optoma HDMI port and the projector was immediately able to detect HDMI signal. Hope this helps you... kaufmanekpr

I have an optoma HD20 and it connects using a 1.5m HDMI but as soon as i try a 10m HDMI connection (even with a booster it does not connect) any suggestions welcomed?


Hi kgomer782 I have similar issue. My optoma hd20 signal connection with a 3/6ft hdmi cable is perfect. However, no signal is detected when connected to a 35ft hdmi 1.4 cable. The 35ft cable is indeed working becuase I tested it succesfully when connected to a 1080p HDTV. Did you received any solution to your problem? I wonder if it has anything to do with the HD20 design of the "debossed" hdmi ports that prevents the cable plug from getting completely "seated" in the port? My 35ft cable has a flat square male ending however, the 3/6ft cables have slim male ending that seems to accomodate perfectly in the Optoma's hdmi port design...kaufmanekpr

Poor picture quality & audio reception


If the input to a HD tv is not in HD format the tv won't display an image very well. Be sure your input to the tv is compatible with the tv's technology for optimum performance quality Also re-check the input source (such as converter box, dvd player, etc..) and be sure you have the correct input/output ports connected properly. Try to reset all yout tv settings back to manufacturers defult specs. When an input signal is sent to the tv most modern tv's have software built in to select the proper format to display the input image. There may have been a mismatch communication error when your tv software tried to "handshake" with your converter box input signals from its firmware. So try a reset solution and re-connect the tv without the converter and see if that helps. If not e-mail me and I'll determine if the tv needs technical servicing.

Blue screen


It sounds like your kid switched to a different input. I am not sure what you have hooked up where but on your remote at the top there are two buttons - one is labeled HD.S and other is SD.S - I do not have my remote handy but am going from memory. The HD.S button switches to the hi-def inputs and the sd.s switches to the standard definition inputs. Try pressing these and switch around until you see a signal again. You will need to let the input "stabilize" and the picture appear so when you switch inputs give it 10 seconds or so before moving on.

Receiver won't put out sound to LCD Sharp aquos


I have the same problem with my Sharp Lcd and Onkyo 804. I believe one problem is that the TV can not accept dolby digital or dts digital audio signals through HDMI. It will play sound if it receives a PCM signal through HDMI. You can try switching the type of signal on the cable box settings and on the dvd player. I switched to PCM and got sound through the TV and the receiver. The problem is that PCM is usually only a 2 channel signal and Dolby 5.1 will sound better through the surround sound theater system. I have not found an absolute solution to this yet, but I am willing to not get sound through the lousy TV speakers in order to get top notch sound through the Onkyo.

Shadow box/signal block?


Check the closed caption settings. To me that looks like the TEXT mode is turned on.
