Hitachi 50UX23K blows main fuse when just plugging in coax or anything in back
Whenever I plug in my vcr or dvd player or the cable line into the back it blows that main fuse. I've tried both unplugged and while plugged in. Also, S901 relay was removed and I put 2 jumper wires in place of it as a troubleshooting step due to the tv not even turning on. It turns on now, and can flip thru channels but as soon as I plug in the cable (coax) or the vcr, it shorts it and pops that main fuse????
I've spent hours on this!! All capacitors / resistors look fine with no bulging. I even checked the capacitors with ohm meter and all appear to be same resistance. Where can i get an S901 relay or equivilent? It's an OEG 12v /250v /10A / 30A ???? relay

You may a grounding (short) on the coax connector on the set. The connector should isolated from ether side of the AC input of the set. Take a ohm meter, set it to 1K. and test between the coax connector (both the shell and center pin) to both sides of the AC plug. You should get NO reading! If you do, their is a short. (The coax cable is grounded where it comes into the house). As for the relay, try Fry's electronics.

these are not cross compatible an rca hook up is a base band signal basically raw data, and coax(cable line) is a frequency with a carrier best suggestion I have is to buy a vcr with a coax out put and rca input that way the vcr can pick up the video signal then remodulate it onto a channel frequency and send it to the tv
Yes there is a possibility that something shorted... remove the cable wire and unplug for 10 to 30 min and try plugging back in and restarting the set. otherwise the tuner probaly would need replaced. something any tv tech can do. AT the shop we replace these conectors al the time. just depends how bad the tuner is damaged.
you will only be able to get digital surround( dolby digital ) from your dvd player( by the coax or optical digital connections ) , the rest will only be in virtual surround
from the dtv box plug the yellow video jack(RCA) into the vcr video input , then plug the audio jack or jacks into the audio input on the vcr. from the vcr hook the audio out to the audio in on the reciever( tv/vcr/sat... input ) , then also connect RF out from the VCR to RF in on the TV .
for the dvd player hook the "s-video out" to the "s-video in" on the tv , then the audio L and R on same s-video input , then send the audio out connection on tv to L and R input on reciever dvd L and R input , then you will need to connect the optical from the dvd player to the reciever or coax connections for the dolby digital on the reciever to work
If you have a VCR you can run the video out from the dvd player to the input of the vcr. then run the vcr coax cable to your tv. You have to set the tv on channel 3 and the vcr to line in. You set the vcr to line in either by scrolling the channel down button below ch 2 (the display will say "LINE") or find the "input" button on the vcr's remote control and scroll through the inputs untill you see your dvd movie playing.
I assume you are using a cable input, such as a box or the main Cable line connected directly to the TV. examine the main Cable Coax, look at the copper wire that sticks out from the connecter, make sure it is long enough, if its to short, gently pull it with a long nose plier until it reaches the rim of the connector. Sometimes when connecting the coax to a source, the copper wire in the coax is to short to make contact, and as a result you get no signal. Hope this solved your problem.
Your DVD player may be set up to put out a different mode. Are you using the component cables or s-video? If it's the component cables, make sure you're player is putting out 480p. Also, try it with another set to see of you can localize the problem.
Usually caused be a secondary device. If you guys have a cable box try this test. Unplug the coax cable from the back of the cable box. plug the coax cable from the wall directly to the TV and do a chennel scan. See if the probelm is still there. If it is TV needs service. If it is gone...it is your cable box. Call the cable company. If you have Satelite all you can do to test it is try another device and see if you have the same problem. A dvd player, VCR, game console etc. and see if the problem happends with that as well. If it does then the TV needs service.
have you tried other devices for input...vcr, or other dvd players to see if it is a problem with the player or with the tv? Check the output setting for the dvd player (1080i etc) and ensure you are connecting to the proper inputs for either analog or digital signals (RCA inputs or RGB).
