View Full Version : Help please! I think I messed up our HDTV 51' with my TV tuner card..
Ok so I bought this TV tuner card for my PC.. so I can watch TV on it... anyways I told my dad im gonna get a TV not telling him I got a TV tuner.. and I told him to hook up the coxcial cable... so for better reception he put the cable directly out from back of the TV.. so then I hooked up the cable to my TV tuner card.. and voila I had very nice reception and could watch tv on my comp... then the horror began.. a day later.. my sister turned on the tv and said hey whats wrong with the tv... and i looked and the writing was wavey... there was neon green and red shadows everywhere under things... it was really trippy.. we tried everything to fix it.. checking all cables.. settings in the TV.. no luck.. then my dad is really mad at me now that I didnt tell him that I was hooking it up to my tv tuner card.. but I told him to a tv.. my mistake.. and that might have shorted out someting being directly from the tv to my computer.. so what do you guys think? is this unfixable? do I need to call repair man... sigh... bad day for me. thanks for anyones help
its a Panasonic HDTV Cinema View 51' Projection
I would doubt that you did the "damage" to the TV. Perhaps it's a simple terrible coincidence. You say the coaxial cable is connected from the TV to the computer, this should not have any effect on the TV. Instead of going "through" the TV, it may be better to put a splitter "upstream" of the TV and the computer.
I sure hope I didnt cause it, my mom and dad seem to think the computer shorted out someting and are very mad at me lol. tv man says it will cost 300 CAN to replace.. ouch.. do you guys think I might be able to sue panasonic or asus? because it doesnt say on either manual that there might be some conflicts with using tv tuners.. or the tv tuner not working on some tvs and risk of damage etc.. and it says on asus manual u can connect it directly to the back of the tv.. but that can only happen out once I figure out if it had anything to do with the tv tuner

Well, if you were connecting the television directly to the back of the computer, per Asus' instructions, you would be displaying your computer's video signal onto your television screen.
If you were connecting an antenna, cable box, dvd player or satellite receiver to your computer, with a Coaxial, A/V Cable or S-Video cable, than you would be sending that signal into your computer's video card to be viewed on your computer monitor.
It sounds like you had performed the latter, connecting an A/V source to your computer's video card. If that's the case, than there is no way I can imagine that you damaged the television by your actions.
What's your cable source - is it just basic analog cable? Do you have a cable box?
u guys dont understand what im saying.. lemme make it more clear.. there is no cable box or splitter or nothing.. tv cable running to my big screen.. below that cable was a connection for out.. i connected it to that and put it onto my comp.. so i could watch tv on the comp and still have tv on bigscreen.. seeing that this is a direct connection right to the tv.. comp may have shorted out picture?

The connection on the TV is an output. A loop... which is okay. It should send the signal to you PC okay.
I think where you may have 'fouled' up was trying to send a signal from your PC to the TV over the connection.
In other words... you tried to do a 'gazinta' on the 'gozouta'.
Ouch... I'd be miffed at you too! :(

Based on what's he's saying he was just trying to use the out on the TV to feed a signal to his tuner card to watch tv on his PC also, that shouldn't have caused any issues with the TV... My guess is he zapped the TV with a static charge or knocked something lose in it while connecting your cable to it...

Based on what's in bold... there's still a question about what was done.
Agreed... if nothing 'fancy' was attempted to output from the PC to the TV, it shouldn't have caused a problem. Unless the PC sent a 'jolt' to the TV via the PC over the coax.
ok the repairman came over and told us there is 3 problems with it.. one is the video converter or w/e it is and other stuff i forget.. anyways he said never play xbox or consoles in general on projection tvs.. because they cause it to overwork the tv to much.. thus killing the components much more quicky in a shorter period of time.. wow that is really stupid if u ask me.. never gonna get a big screen again.. dumb bs

HAAAA video game consoles can make the tv work harder thats the dumbest thing ive ever heard that tv repair man is an idiot..... the only thing a video game can do to a CRT based RPTV is cause burn in and thats only if you leave a static image on screen for days.....

Too many inconsistencies on this thread to make any sense of it!

Have you tried just disconnecting the cable going to your computer and checking the picture on the big screen? You should put a splitter in coaxial cable before running it to the tv. Then use one connection to the tv and the second to your computer tuner.

I, too, am having a hard time deciphering this one... :headscrat
...doesn't sound good, though.

Well, it was pretty cut and dried until he mentioned the video game. Some TVs have an output which simply passes the signal and eliminates the need for a splitter to feed the PC's video card. This, by itself, should not have caused any problems.
However, it now sounds like there is a video game console in the mix. Since this does feed the TV, it's possible something in this circuit shorted something in the TV's video circuitry, especially since the repairman, idiot that he appears to be, mentioned a video converter or whatever he called it.
It seems rather obvious that the PC tuner did nothing and it's simply a coincidence that the TV died at the same time the PC tuner was connected. That doesn't mean something couldn't have shorted out through the PC tuner circuit, but it's highly doubtful unless there were severe thunderstorms, etc., that night while things were powered on.

How old is your TV? I must say I laughed when the TV is being over worked if you play video games on it. Not at you Grin, just that idea itself. Ludicrous to say the least. Have you disconnected the cable from the TV output and checked the TV picture again? Still does it? If yes, it sounds like you need a new fitting (connector) on your cable. The cable guy should take care of it for you. As unlikely as it is that your computer card generated a backfeed to the TV, take the advice of splitting the signal BEFORE the TV using a 2-way splitter, again, available from your cable company. Also be sure to check and ensure that the cable is GROUNDED to power company ground or a dedicated ground rod. Here in the States the code calls for a 5/8" x 8' ground rod be sunk. Unless you had problems with your set before, don't waste any more money on guys that are trying to sell you something you most likely do not need. Video games cause a TV to be over worked--- :rolleyes:... :smokin:
