Do You Need Service On Your TV?
Many problems with your TV can be caused by other issues, so first verify whether your TV is defective. You do not want to buy a new TV only to have the same problem after its hooked back up. This is very frustrating. Use this guide to go through the same process our on-site AV Techs use to verify if your TV is in need of repair or if you have a less costly problem.
If you live in the Phoenix area we can come out to your home for 29.95 and verify you need a repair. While we no longer offer Repair services in most cases (See here if you want to know why TV Repair is not cost effective or too frustrating to consider in most cases) If it makes sense for you to consider a repair we can help you pick a reputable service center so you can go that route. We can often give you an idea as to what a cost range might be as well. If you are comfortable doing a repair yourself then we can give you some guidance there as well.
Does the TV have one or more thin red, green, or blue vertical lines? (thin like a pencil line)
This can either be a defective panel or a driver board. If it is a driver board, then only the main or power boards can be bad causing the driver board to malfunction. Please note that only plasma TV's contain driver boards. More often it is a defective panel. LCD/LED TVs' driver boards are part of the panel and are not available separately. Horizontal black lines can be caused by a driver board issue, and vertical black lines can be caused by a defective panel.
Does the TV have a Dark Picture?
If the TV is an LCD/LED and you can barely see a picture, then you have a backlight problem which can be caused by a defective backlight drive circuit or open LED String inside the panel. Neither problem cannot be confirmed without removing the rear cover. If the TV is a plasma, then the problem is caused by one or more scan boards. Again, the problem cannot be confirmed without rear cover removal.
Does the TV have a Washed out Picture?
If the TV is either a Plasma or LED/LCD, then the problem is almost always the main board. If the B&W is okay but the color is washed out, then the problem is the panel drive or panel.
As the picture changes, does the last picture linger?
This is almost always caused by a defective panel. In rare cases, it can be caused by the panel timing controller.
Are the Colors off?
If it's using component input, then either red, blue, or both are defective. If the green is defective, you will not have a picture.
Does the picture have a orange tint?
The blue cable is defective.
Does the picture have a cyan tint?
The red cable is defective.
Is the picture black and white?
Both the red and blue cables are defective.
If you are using HDMI, then first try different HDMI Devices.
Does the TV have a distorted picture?
It it's on all inputs, go to INPUT PROBLEMS.
If not, replace the cable on the affected input. Try resetting the device connected to the affected input. (Unplug from Power, wait 5 minutes, then plug in and retry)
Does your TV turn on, but doesn’t have a picture?
Press the menu button on the TV. Only use the menu button on the remote that came with the TV (ensure the remote has the same name as the TV). Does the Menu come on?If so, then it is an input problem. Go to Input Problems. If not, try unplugging the TV for 5 Minutes, then plug in and power on. Does the menu come on now when button is pushed? If not, the TV needs servicing.
If you can display the TV menu, but still have no picture, then do the following.
(A) Look in the back of the TV and see what inputs are being used. HDMI 1,2 etc., component, composite, antenna or cable. HDMI uses one cable. Component uses 3 video; 1 each red, green, and blue, and 2 audio; 1 each Red & White. Composite uses 1 each yellow, red, and white.
(B) Try switching to different inputs. If you have a picture on other inputs, then do the following:
(C) Try resetting the Device connected to the input in question. (Unplug for 5 minutes, then plug back in and retry)
(D) If there are still no results, try a new connecting cable.
(E) If you have devices connected to 2 or more HDMI inputs, try connecting each device to each HDMI input one at a time. If you still don’t have a picture with any of the previous connections, then you either have 2 or more defective HDMI devices or HDMI cables. However, it could also be a defective main board that requires service.
(F) If you have a device connected to a component input and don’t have a picture on that input,unplug the green and white cables at both ends. Plug the white cable in where the green cable was connected (leave the green cable disconnected). If you have more then one component input, then try them all. Also, if you have more component devices, try those as well. You only have to connect one cable to the green input on the TV and the green output on any component device. The picture will only be B&W until you hook up the red and blue cables.
(G) Another test is to put the TV in the TV mode. Unbend a paper clip and insert it into the antenna connector. See if you can pick up any channels. If not, try to auto program for air (not cable).
(D) Many TVs have additional inputs (computer, USB, and internet).
Is your TV Dead? (No Power Light)
(A) Try plugging in the TV to different wall outlets.
(B) Plug a lamp in the same outlet to make sure it has power.
(C) Make sure the TV’s vacation switch is in the on position (only a few TV’s have these). Vacation switches are usually located on the bottom edge or the left side of the TV.
(D) Try the power button on the TV. Some TV’s have a touch panel, instead of buttons, and that is usually on the bottom of the TV frame on the right hand side.
(E) If you are using a cable, satellite or tivo remote, try using the remote that came with the TV.
(F) Try unplugging the TV for 5 Minutes, then plug in and retry to power on.
(G) If the power cord is removable, try a replacement.
Does the TV have a power light that is lit, but the TV will not turn on?
(A) Try the power button on the TV. Remember that some TV's have a touch panel.
(B) If you are using a cable or satellite remote, try using the remote that came with the TV.
(C) Try unplugging the TV for 5 minutes, then plug in and retry to power on.
If the TV doesn’t have Sound on any Input.
Using the original remote, go into the TV menu. Go to audio menu and make sure the speakers are turned on.
Does the TV have sound on some inputs, but not others?
If the sound problem is on HDMI, then try another HDMI input, another HDMI Cable, or if possible another HDMI Device (Blu-Ray DVD Player, Roku , Apple TV,etc.). If there's no sound on component or composite, but HDMI is okay, then disconnect the audio cables from the device, turn up the volume on your TV, and touch your finger to the center pin without touching the outer metal part. You should hear a buzz. If you do, then the problem is with the device. If all the above tests fail to produce results, then service is required.
If you have a hum in the audio on any input, then you probably have a defective audio cable or device that’s connected to it. If the TV has distorted sound on all inputs, it would require servicing. If it's on more than one but not all inputs, most probably a defective main board which requires servicing. If only on one input, its most likely a defective cable or device connected to it.
