Re: vizio amber light E321VL

I just bought one of those eeproms. Didn't fix the board/tv.

Turned out to be a bad solder joint. I resoldered parts in groups, so I don't know exactly which part was the problem. But, I have a pretty good idea.

Those resistor packs around the main IC do not have legs. The contacts do not necessarily touch the pads. So, in order to make contact, you have to bridge the solder joint. That is a good way to have a bad contact.

Anyway, after soldering all the r-packs, the tv works! Yea! I would suggest resoldering all the r-packs on both sides of the board near that main IC.

Good luck!

(anyone want a $25 chip )

Re: vizio amber light E321VL

I got a e321vl that power on(backlight is on) but no picture.
Any suggestions ?

See the post directly above yours. These old posts don't get the attention because people think the problem was solved or the OP gave up. So just start a new thread with good, focused top down pictures of both sides of each of your boards. Also one picture with all the boards hooked up (as if you just took the back off). We want to be able to read the writing on the boards.

Re: vizio amber light E321VL

You need to start a new thread on your tv. Take good close up pictures of the front and back of your power board and mainboard. Post them with the Manage Attachments button below in the Additional Options section. You will be helped to figure out your problem if it is possible to do so.

Will do, thanks!

Re: vizio amber light E321VL

Wanted to resurrect this thread again to see what the experts think about my problem. I have a Vizio M420NV LED TV that turns on, runs flawlessly for about 5 to 10 minutes, and then the picture freezes and fades slowly to black. It then continues to do this over and over again. Do any of you think this could also be the EEPROM? Or some other problem...?

Re: vizio amber light E321VL

Make sure the chip polarity is correct. There is a small recessed dot on the corner of the chip. It should correspond to the dot showing on the circuit board drawing where the chip is installed. Also be careful of static charges when handling the chip.

Just to let you know the eeprom was fine it turned out to be solder bridges on the main video chip. That was mentioned on another post or maybe earlier in this thread. I think the eeprom replacement would have solved the problem without the solder bridges being there.

Re: vizio amber light E321VL

See post #95.
I want to thank RetiredCaps and BudM for their help. This was my first foray into the TV repair business. I don't know if it is just Vizio's or if most of these LCD Tvs have problems like mine did. Sure seems like repairing monitors is a whole lot easier.

Maybe the manufacturers are building in an income stream with product that will die in a few years ala the old (Fix or Repair Daily) Fords. I guess they figure we have gotten used to the disposable idea of when it quits just throw it away and buy a new one.

Re: vizio amber light E321VL

It probably just has another number. Check your board very near your large main video chip. My board had a square outlined with a white line around the main video chip and the EEProm was inside that square. The video chip will be the largest chip on your board. The EEprom chip will be a good bit smaller, rectangular and have I think 16 legs, but could have as few as 8 legs. It should be very close to the large chip.

Re: vizio amber light E321VL

Thanks Killian6pk. I can change the eeprom for e321vl, but I cant find that same chip on a different model tv, e3d320vx, it does not use the same chip

Re: vizio amber light E321VL

I m having the same issue with my E3D320VX model, and help guys? I looked at the board on can find the eemprom to change. Please help me anyone who can

The EEProm has to be programed. If you buy them from Ebay or Digikey etc. They will not be programed. One of the members here Miguel from iTVRepair offers to sell you a programed EEProm for $25.00 including shipping. If you don't have experience unsoldering surface mount components this chip can be extremely difficult to change. Miguel will also let you send him your Main Board for troubleshooting and also your Power Board. His phone number at his shop is 972-642-9554 he is located in Dallas.

As far as location of the EEProm; it is located below and to the left of your Large Video chip on the Main Board. The part number for my chip was MX25L6406E, your chip may have a different number but will probably start with MX I would call Miguel and talk to him to see if he can help you.

Disclosure: I don't know Miguel (other than from the Board), I'm not married to him (or shacked up with him) and He does not pay me for referrals. So take this info as you find it.
