Dynex DX-LCD37 TV - Page 2 Questions & Answers
Tv has no picture
If you have lost your picture you can try a few steps. The first step would be to reset your receiver by unplugging it for ten seconds. If that does not resolve the issue, you will need to check the cable going from the receiver to the TV set. Start by making sure it's firmly connected. If the cable is a coax cable (screws on) tune the TV set to each of the following channels to see if you can get a picture: 3, 4, 60, 73 If you have a digital cable that just plugs into the receiver and the TV then you will want top cycle inputs until you receive a picture. To do this press the input or source button on the side of your TV you will see the name of the input flash at the top of the screen. Press the input button multiple times to change from one input to the next. Make sure to pause on each input for a few seconds to make sure the picture comes up.

My TV "Dynex DX-LCD37" shut
Since the TV is new I would suggest that you must not attempt to tamper the TV and give up the warranty on the set. So the best is to have an external check, remove the power supply and let the voltage drain off in the set and control panel, depress the control panel /start /standby switch/prog. switches.
If the set after this reset still prefers to shut down after a time period then there is a hardware issue on the processor section and it can be relative to hanging of the system.
I would request that you file for warranty free service immediately.

Hello,
The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.
All these can be checked on the power supply board.
But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.
The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)
You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.
What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).
You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress from www.shopjimmy.com
Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.
I hope this helps.
Regards.

You will need to press the "Format" button on your DISH remote This button will have a * on it. By pressing this button repeatedly, you can change the format of the screen set it to normal. Next grab the factory remote for your TV and try the different formats most likely normal will work best on this setting as well.

Tv shut down while watching
maybe the problem is in the cathode light located on the top of your screen. Is there a signal light on your T.V? a green light or maybe a red? if there is a green light then we can say that the problem is the the cathode light or maybe the power supply of the cathode light is defective in that case we can use a power supply of a cathode light that usually used in motorcycle as a signal light.If the signal light is red maybe the problem is in the power supply or maybe the main board of your T.V. Hope this may help you.
Half the screen doesn't work. It goes black
You need to go into the back of set and look for the wire connection to the board that is top center (looking from the back of the set). The wire plug will be about 1 and a half to 2 inches wide with several wires on it. Carefully unplug the wire going to that board and take a pencil eraser and clean the contacts gently and carefully. Plug it back up. The wire mentioned will come from the main board (with all the jacks and connections).

You should take the TV back to Bestbuy when you get the chance... Tv could of came defective from the factory. They should be able to exchange for a new one if you explain the problem to them.

Those colored lines are a bad panel. Is no button to make them go away. The only fix is to replace your panel. Would be more cost effective to replace the TV.

Hello
Try the resetting the TV. To do this unplug the power chord from power socket, and wait for atleast 45 minute. TV will reset itself. The try to get signals.
If your TV receive poor quality telivision signals, captioning may contain errors, or there might be no captioning at all. Some possible reasons for poor quality are automobile ignition noise, electic motor noise, weak signal reception or multiplex signal reception like ghosts etc.
If reset also didn't help you, the tuner inside your TV is defective, or weak. It should be replaced with same type and number. OK.

Do you have a cable or satellite box connected to the TV? If so the box is probably what is providing the Closed Caption and not the TV.

I just purchased a Dynex
Hi,
I think you will find that all of your channels are still there. If you are using digital or digital and analog channels, some of the digital channels may be on "sub-channels". This is explained on page 14 of your Dynex user manual. For some channels you will need to enter the main channel number - e.g. 8 - followed by a decimal point, then the sub-channel number - e.g. 8.3
The decimal point is below the 7 key. The easiest way to check whether you have sub-channels or not is to press the GUIDE key in the top-right corner of the remote for a complete list of the digital channels.
It's difficult to determine what is causing the 'fuzzy' picture. I would advise you to disconnect the coax connection at the back of the TV, inspect it for any damage, then re-connect it. It could also be caused by interference from another electrical device. Some TVs have better interference suppression than others and it's possible that your old Toshiba was better at eliminating interference.
There is also the possibility that you bought a lemon. I suggest you concentrate on making sure you have all the channels first then we can look at possible reasons and cures for the fuzzy picture. You don't want to spend too much time (or money!) getting it right if you can't get all the channels and you end up returning it to the shop.
Please check for the digital sub-channels first then reply to me by clicking on "Add a Comment" below your question.

No picture..sounds is fine
Hello,
Problem is in either power supply or the Y-Sustain board.
The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.
Often there are fuses on that board - one or more. Check those.
if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.
I hope this will help in solving the problem, also do take caution in handling the television because it contain high voltage....
