My dynex tv has a backlight on but wont work

The tv will light up slightly with the back light but it will not get the actual picture. It is not the box I had my cable company come out. The cable guy said he thinks a power surge blew a capacitor. He said it happened to his samsung and it was a $1.50 fix

SOURCE: Insignia NS-32LCD Backlight or Inverter bad???

If you've done the flash light test, it could be the inverter board became defective but it could also be that the power supply does not provide the +24VDC to the back light inverter board.
If you could do the +24VDC test using a voltmeter then we can say for sure that the back light inverter board is defective.
Let me know if you need further assistance.

To eliminate power in as a problem get a small battery backup type UPS. This will eliminate power surge spikes, brown outs and for short time periods blackouts. Yes - these TV's are suseptible to power problems.

SOURCE: Fuzzy pic on Dynex 32 LCD TV

I am sumising that you have checked the menu controls on your tv and are recieving your signal from the cable box , so therefore if it is not comong from the Aerial and direct from the cable company then the picture should be clear .. However sometimes people dont check to see if the signal is RGB or composite from the box RGB is usually best if you have a scart socket connection or SVHS if your set has that capability .. sometimes people have an old VHs recorder and the sinal is coming from that to the set through the Aerail fly lead if it is you will probably find they are conflicting giving you a poor picture retune your Video to another channel instructions should be in its manuel if not come back to me ... reagrds Vortash

SOURCE: Killed by lightning, have power, no picture...

The warranty does not cover lightning, check if your insurance covers it.
A lightning strike on such panel ( HDMI ) is very difficult to repair and if not impossible.The HDMI connector is hooked to the ground of the TV set so everything could be damaged.
My advice is not to repair.

Give it a try

Why LCD TV have No Picture only sound


Flat-panel LCD TVs have a lifespan newly approaching 100,000 hours on average. The lifespan of an LCD TV is generally longer than that of similar-sized plasma televisions. Some manufacturers even claim that their LCDs can last upwards of 100,000 hours when used continuously under controlled conditions (e.g., in a room with "standard" lighting conditions and 77&deg; temperatures throughout). Just how realistic such claims are is debatable. After all, whose living room has no windows and remains at a perfectly comfortable 77 degrees year-round? <br /> In any case, the pictures on fluorescent backlit LCD TVs will show some "wear" because they are generated by powerful lamps, which, like any lighting appliance, will dim over time and with use. The picture you see will dim ever so slightly as the backlighting bulbs dim. One other consideration is that CFL fluorescent backlighting will change colors over time. This will change the white balance on your TV and cause color calibrations to be thrown off. <br /> Therefore, the most important thing to consider when it comes to the lifespan of your LCD TV is the actual lifespan of the light source in your LCD. LCD TVs last as long as their lightsources do. So, the lightsource in your LCD TV is the critical component of your LCD display unit. Newly introduced LED backlit LCD TVs will have the best long term performance. LED backlighting is superior in that the white balance of the TV will not be affected by changing bulb color over time. It's a more consistent bulb technology and will also maintain its brightness longer. <br /> The edge lit version of LED TVs will use far less energy while local dimming LED backlighting will be more accurate and present a better picture while using more power. We believe that local dimming LED backlighting will be slightly less stable from a life span standpoint. <br /> To ensure the integrity of your lightsource for the duration of your LCD display's lifespan, you will definitely want to adjust the CONTRAST setting of your LCD TV. Too high of a CONTRAST level will prematurely age your lightsource because it will have to work harder to maintain such light intensities. Your best bet is to keep your CONTRAST set appropriately for the conditions under which your view your LCD display. Brighter ambient light levels require slightly higher CONTRAST levels, while lower ambient light levels demand less CONTRAST <br /> If there is sound but no picture, only sound it has more chances of faulty back light repairable from Service Support. <br /> Hope this helps, if so do rate the solution. <br />

I have a dynex flat screen model number dx-lcd32-09 it has a white transparent screen how do i fix or what do i need


This sounds like the TV has a good backlight but no video signal to the LCD. Additional diagnostics are needed to determine where the fault actually is. Most likely its the board but it could be the panel itself. You will need to track resistance between the parts and possibly the current as well to find the exact fault.

Some parts for the TV are available here: http://www.partstore.com/Model/Best+Buy+Company+Incorporated/Dynex/DXLCD3209.aspx . ShopJimmy.com may have parts from slightly used TVs of this model (QC and then damaged in shipping).

I hope this helps.

Dynex Flat Screen 22" w/DVD


When the picture goes out, try to open and access the TVs menu using the Dynex remote. if the menu fails to open up you can bet there is a problem with the backlight on the TV. Letting the TV rest and then it working again indicates heat as the source of the problem. Check to see if your still in your 1yr warranty or if you have a protection plan at best buy, the TV needs help.

If the Menu were to still open, you can blame your cable/satellite set top box.

Picture goes out but sound remains. After restarting picture is back. Recently the picture would not come back after restart. Next day it worked again.


The tv have 1 or 2 long LCD inverter boards are dying.These 1 or 2 long LCD inverter boards help the tv to have a backlight to produce a picture on to the LCD screen panel.Tries websites like Shopjimmy.com,Ebay.com to buy those 1 or 2 LCD long inverter boards for the replacement.

I have a Dynex 19"


Test: You might see a pic by shining a bright light against the screen. (Halogen can burn a spot if too close for too long like 15 seconds). If so, you probably have an inverter, backlight tube or coil/driver board problem. Some of thse units have a bad ground on the tube driver coil board which can be shimmed and/or tightened. Sometimes a simple car light tester (continuity tester with a 12v bulb) from casing/mount ground to any of the - side of the backlight driver coils will light the screen and reveal which tube is non functional. I leave one dome light running in such ground position one of my TVs at all times for regulation and night dimming.

MY DYNEX TV MODEL DX-LCD19-09 TV PICTURE BLACKS OUT BUT PICTURE COMES BACK IMMEDIATELY. CABLE PROVIDER HAS REPLACED CABLE BOX ON SEVERAL OCCASIONS, CABLE BOX OPERATING OK. PICTURE BLACKOUT CONTINUES.


Does it black out on all video sources? If it does, then you will need to inspect the power supply module and the backlight inverter boards.
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there are some troubleshoot you will have to do to find out the causes of the problem you are having.

Dynex tv no picture screen comes on and then goes black


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.
