Hi


Thanks for using FixYa. From what you have described it seems that you might have a backlight issue with this TV set. It could also be due to the inverter circuits for the backlights. The inverter is the power supply source for the backlights. There could also be a screen driver problem; if it is then you have to change the entire board. All this is only recommended if you have some kind of expertise for checking the internal circuitry of the TV as these units have high voltages running even when the set is switched off.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks
Rylee

Lcd tv has sound but no picture, checked the inverter board and light is coming on the screen but no image


1. Symptom: Powers up, relay clicks, LED turns green, backlight comes on but there's no display from any input, and no OSD.
Solution: On the T-Con board labeled 320WTC2LV3.7, stickered J01420PE7F0288, check/replace:
F1 = 2A, 35V SMD (measured 9 Megaohms in circuit) - OK!

Unless this JUST started happening AND the TV worked previously, or you recently added a device to your set up, I am guessing that you simply are on the wrong input. For instance, I have a playstation connected to Video 2 and if my TV is set to Video 2 input AND my playstation is NOT on, the screen will be lit, but no picture. Make sure you are on the correct input.

JVC LT-24HD32J TV SCREEN GOES BLANK AFTER 10 SECONDS WITH JUST THE SELECTED CHANNEL DISPLAYED.


Good day!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Et powers on, has jvc logo, has sound but no picture


Backlight is defective.
I suggest placing it on Ebay and using profits to get a new TV.

Backlight replacement is possible, but the bulbs are unavailable so it would be required to purchase similar model from ebay to get them. There are other methods but this is the easiest.
