Question about Vizio Televison & Video

1 Answer

Have Vizio E60-c3 LED TV. Picture not working, Backlights on, Audio works. Ordered Complete repair kit from Shop Jimmy.

Replaced Power Supply board, Main Board, Tcon Board and ribbon cables to and from Tcon board and cable harnesses from Power supply board to Main board. Same result. No Picture, Backlights on, Audio works. Checked voltage on ribbon from Main to Tcon and 12.5 volts on both ends at solder point 1 and solder point 51, respectively. No voltage to ribbons leaving Tcon board either side. Checked Gate and Drain and Source on Tcon Board and 0 volts. Any ideas now? or did I get sent a bad Tcon Board.

About 99% of the boards from shipjimmy are good, unfortunately lI think you have a bad panel and its destroying the tcon board, did you check the fuse on the tcon board?

    Did not know they have a fuse. I wondered about the panel shorting the Tcon.

  • Larry Feb 22, 2018

    Chances are there is a fuse on the tcon as about 90% of them have a fuse, its extremely small it will be marked f1 its about a 1/16 of an inch wide and quarter inch long and generally they are white. Unfortunately if that fuse if bad the panel is as well, I don't think Ive ever had an instance where the fuse was blown and changing it fixed anything, the bad panel takes out the timing IC and that blows the fuse. You should be able to sell the other 2 boards if you want on eBay to get some of your loss back, but don't try selling the tcon as I'm sure its bad.

SOURCE: no picture power ups blacklights work no menu no

If you see the back light, then you should have 24vdc on the main power supply board which it gets the turn on command from the maun board. If you do have all those voltage, then it does sound like you need the new main board.

SOURCE: I have a VIZIO VW32LHDTV20A tv I have audio comes on and stays on like it should but no video the back lights are on.

LCD simple panel check. In a dark room, (does not have to be total), shine a flashlight at it with a station tuned in. If you see images
and you have changed the panel HV board, your flourescent tubes could be bad. If you dont, then check the cabling.

Did you try repairing the PS with a repair kit first then replace both the boards after that?

I have a Vizio E500i-A1. I have backlights and sound but no picture. I have ordered and replaced the tcon, main board and power supply board. Still no picture. Any Idea what the problem is?


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

What's my next step in diagnosing my Vizio LCD TV picture issue?


Hi Tim,
If all the boards you replaced were good and working, the only thing remains is the panel if the backlights are on. Please see that the LVDS cable is carrying voltage to the Tcon board.
Good luck.

Tv has sound but no picture, nothing shows with the flashlight test, all inputs have sound but no picture, installed a new t-con card with no results ?


Use a voltmeter to verify the different voltages on the power supply board are present within tolerance. Look for discolored , puffy or domed capacitors. Repair kits and complete replacement boards can be had from: TV Parts Universal TV Stands DLP Chips ShopJimmy

LCD TV Has Sound, Backlights Work, but No Picture


I have been having the same problem with my LG. people say there are bad capacitors on the power supply board. I don't have the know how to replace them and don't have the money to pay. I can get mine to work by blowing hot air with a hair dryer into the back of my tv through the vents over the board. Heat it up for a couple minutes and turn it off and then back on and the picture comes back. I just never turn the set off now.
