Question about Mitsubishi VS-50605 50" Rear Projection Television

4 Answers

No picture When the tv is turned on all I get is a snowy screen. I changed cable boxes to make sure that wasn't the problem. It wasn't. When I press the menu button on the front of the set, the menu appears so I do get a picture there, but thats all.

Normally, snow is an indication that there is no signal from the tuner. Bypassing the tuner by changing to a video input should show you a blank screen. If you still see snow, it suggests that the set has not switched from tuner mode to video. I would look for a missing voltage in the power supply. I wuold look for a missing 12V supply.

You either have a bad coable connection or a bad tuner. The snow is because no signal is being detected. This can be a bad tuner or a bad power feed to the tuner. From a repair perspective it could be as simple as a bad connection inside the set that stops the power to tuner. If you feel comfortable working inside the set and can solder, resolder any connections that appear grainy or have rings. If that does not resolve the problem, you may need to request service.

Please note that because the menu shows up, the majority of hte set is working correctly. You should also try one of the video inputs. I suspect that they will work as well. If so, its another vote for a bad tuner.

Usually a snowy picture means that you have a bad ground connection. You should see that some channels are beter than others. Verify that the cable connection is good. Try a different cable if you can. If that has no effect, than we need to start looking at the tuner itself. If you can change channels but just have a poor picture, chances are that a resolder of the tuner section will resolve the problem.

Keep us posted.

I can suggest unplugging the TV and leaving it off over night. This will do a power reset and may correct the problem. If not the only way to determine the problem with the TV is testing the circuits. For a simple repair you can expect to pay in the ballpark of $100 for the repair.

Hope that helps.....

When tv is turned on with cable channels picture is snowy. when dvd or vhs tape played through tv the picture is snowy


Try using the video inputs
What to do if you have an all snowy picture (blue screen or the TV displays unusable signal-no signal or no sync)
1 – If you are using a digital cable box or satellite receiver (make sure it’s on) and be sure your TV is set for either CH3 or CH4 (which ever you usually view it on). If you usually view it through video inputs (video1 or 2 etc.) make sure the appropriate input is selected.
If you still don’t get a signal see if you get picture using the DVD or VCR (if available) if you do than plug the satellite or Dig. Box temporarily into the place of the DVD (unplug DVD) you may have to use some A/V cables (RCA yel./red/wht like the ones on the DVD) to hook to the tv from the sat./dig. box. If you get a signal then the sat./dig box is ok. If not the Sat./dig box is not sending a signal and is either defective or needs to be rebooted (unplug wait 5 min try again).
2 – If you are using standard cable or antenna (source) if possible check that the source is good by connecting to another TV. Otherwise try running the source into a VCR and then out to the TV using video inputs (RCA yel./red/wht like the ones on the DVD) and then selecting the appropriate input. Try seeing if the VCR plays using standard CH3 (or CH4)
If the VCR plays on video input but not when connected to CH3 (CH4) then the tuner of the TV may be defective – see if you can use the VCR to change channel using the VCR remote.

I just replaCED THE LAMP AND NOW i CAN'T GET A SIGNAL FROM MY CABLE BOX


try bypassing the cable box and plug the cable directly into the TV if you have a snowy picture you might have a cable issue. Also make sure you can view a movie from a DVD player.If your DVD player does not show a picture then you might still have a TV issue but if it does the problem is either your cable box or it's the cable going to the TV either not plugged in or defective.Also try moving your cable from the cable box to a different input on the back of the TV you could have a issue with only that one input (video source).

Bought a proscanlcd hdtv 32lb30Q unable to get cable signal


Hi and welcome to FixYa,

Initially, pls confirm if below is how it is wired using a coaxial cable and not 3cable RCA to RCA:
  • Charter Digital Cable > DVD/VCR > TV
If yes and your concern is snowy or no signal on the TV screen, might it be that you have to power OFF the DVD/VCR when selecting channels on the TV itself (including when channel setup is being done).

Alternately, you can tune the TV to channel 3 and let the DVD/VCR do the channel selections.

Pls post back results. Good luck and thank you for using FixYa.

Snowy picture


Hi,

A snowy video indicates that your input signal is relatively weak. On the other hand, a noisy picture is when there are too much interference is super imposing on the video.

Snowy picture comes about when the signal coming in the RF INput (Ant/Cable) at the back of the unit is below a certain level. If this is the case, then it is not a problem with your TV but rather your aerial (antenna) or the cable from your provider. A way to verify that it is the ant/cable that is the cause and not a defective TV/tuner is to hook up an old VCR set to Ch. 3 or 4 to the RF IN of your TV using a short 75 ohms coaxial cable terminated at both ends with FP-5 connector. Play a known clear good tape and set your TV to Ch. 3 or 4 as the case maybe. If the picture is relatively clearer, better, then you have just confirmed that it is indeed your aerial or your cable (provider) that needs looking into. If on the other hand, the VCR signal is also snowy then chances are that you have a problem with the input stage of your TV including possibly your tuner.

For your aerial problem, antenna orientation or replacing with a higher gain antenna might help solve the snowy signal. For your cable problem, you have to call-in for service from your cable provider. If it is a TV problem, your best course would be to seek the services of a qualified TV technician since this involve electronic circuitry analysis, diagnosis and possible component replacements.

Additionally, you may try looking for any loose connection, loose grounding, broken wire or anything out of the ordinary in your connections.

Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

Picture


yes it could ba the cable itself even, but i suspect more the tuner circuit or tuner itself may have bad solder connections. Here is another test for you to try, plug another dvd or vcr, or xbox etc. into the back, using one odf the inputs. See if this works like the built in dvd. if so it will be more likely bad connections in the tuner or surrounding circuit. good luck.

While watching tv, the tv all sudden goes snowy, no sound, and have to turn it off and back on to make it work again


Connect up another set right next to that set thats going out to make sure the cable or that line is not bad. It soukds as though you may have an intermittant tuner assembly inside the TV set. Its also a possablity that there could be a bad solder connectiuon in or around the tuner assembley. Not really a job for the user, as this set has hot and cold chassis, and can give a mean shock if you do not have the know how to work on these monsters. good Luck PS Please do not forget to rate this thread.
