Videoseven (V7) LTV32DA LCD TV black screen, blinking led
I'm trying this problem again, and hope a TV expert can help me..
The led in the front blinks 3 green 1 red, 3 green 1 red, 3
green 1 red, then continuous green. As it front blinks in a specific pattern I think it's a code
pointing to what the problem is, but I can't find any info on what it
means. Measured the voltages from the SMPS, and all seemed to be
ok. I also found that the Samsung LNS3251DX/XAA uses the same LCD
screen, so maybe solutions for Samsung sets would work on this one?
I don't know if this is of any help in finding info for this set, but
the lcd-screen is marked LTA320W2-L01 and LTY320W2-L02, the main boards
is marked LTV1280H1 Rev.B P/N:511-050-029100 and LTV1280H1_SUB Rev.B
P/N:513-230-004000, and the SMPS is marked Kijin Electronics Co. Model:

Re: Videoseven (V7) LTV32DA LCD TV black screen, blinking...
That is correct in assuming that this is a code and it is related to that on-board processor protocol. Yes, many screens are used on many different chassis, but the ways to the means is not always the same. So, you have a schematic for this motherboard? What problem are you having with this set?....accordianman

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electro-medical.blogspot.com/ http://electronicshelponline.blogspot.com/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
Try a reset. Start by unplugging for 1 minute, then plug back in & if still won't restart try the following. If none of the following work, you will need a technician.
Initializing the TV in many cases can remedy a problem.
In the 2006 product line Initialization is now a user function.

You very well could have problem with the Ballast board that powers Lamp or your Lamp Fan maybe defective and if you need orinagnal hand unit for set Call Encompass Parts Distrubtion or Go to their website type in Model number they will list Parts /Prices for your model.
1-800-638-3328 Mats Electronics also sells handunits .To reset timer
Hold VOL- on front of TV and Menu on hand unit at same time for 5secs
if this does not work try it in reverse Hold Menu down on TV and Vol- on hand unit. Check your Lamp Fan see if it quits running while turning set on,if it starts and stops it is defective, other wise Follow wires that Lamp plugs into it will connect to Ballast board that powers Lamp CK it Problem M/B Ballast Board.
it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the
point that they need to be replaced. Operation of the set in a dirty
environment is not a good idea
same problem as others 3 blinking green lights then orangey colors then 3 red blinking lights afterwards shuts down fan runs for about 2 mins solution check your door cover for warpage or deformed just a bit under set screw there is a push in switch try and push it in with q tip while holding turn on tv if it works then that door is deformed and defective change it
thanks for solving my issue tv works again very helpfull thanks
