Sorry this tv is not worth a whole tv anymore.The tvs LCD screen panels are limited in productions by the tvs corporations.By replacing the tv LCD screen panel,will cost the same as a new tv.The tv LCD screen panel is 90% important to the tv.If it damages or broken than the tv only can be worth as a salvages tv for it electoronic boards for parts,that it.

Check where your plug go's in to your powersupply if it is well fitted. ////sometimes it dosnt make well connection then you will struggle to get it on.

needs pwr adj.....

power supply first one...second one input hdmi pcb defective..

I think I see what happened here. Normally you have the tv cable connected to one connector and satellite or others to different connectors. When you want to switch you use your remote or the tv controls to change the source.This will preserve the scanned channels as well. On your remote you should see source or something like that. As you select it it should shows options like antenna, cable aux1 aux2 and so on.

So hook your tv up and rescan your channels. Then hook up the satellite to one of the other inputs. Then use the remote to switch the source. You will never see more than one sateliitel channel at a time and you will have to use the satellite remote to change channels on the satellite box.

Hello,
The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.
All these can be checked on the power supply board.
But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.
The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)
You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.
What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).
You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.
Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.
I hope this helps.
Regards.

Hello,

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 blown fuses burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc. you have to this with the help of multimeter to read...

- You can look at the sample of the power supply board, the picture with the soldering side has labeling of what you should have on the output of the power supply, yours may be labeled on the top side of the board, there are high voltage on the board so you must be real careful, if you are not sure, let the professional handle it.

Good luck in solving the problem.....

Replace the main unit board.

This is an easy fix. You must remove the shielding tape on the connector where the main video cable connects to the t-con board. The t-con board is underneath the mainboard chassis. I had to do the same repair on my LTV-32W3 32".

I believe this is a generic cord that looks the same as one from a computer or monitor. if this is the case, they are readily available from eBay for very little money(under $10)

smell? maybe something had burn out inside. or something got to hot.

you can start doing the diagnostic, but let it rest a bit.
then, try it again.
if nothing, you will have to disassemble it and check for fuses in the power card to begin.

I did a lot of looking around earlier. It might just be the outlet you're plugged into. Try plugging directly into the wall if you're plugged into a surge protector.

Also, did you remove all of the tape? I removed even the thicker canvas-like material. So the wires are actually exposed, but it's been working great ever since.

Good luck! I'll try to keep helping if I can.

Hello, it sounds like your inverter board is goin out on the set, when you change channels if you notice on almost any TV the screen goes dark and the new channel appears, it sounds like you are not getting enough power out of the inverter board to power up the backlight enough to come on. This is why the sound remains because everything else works fine and the sound is connected to the main board.

Look at the power supply first; look for burnt parts, bad capacitors, etc.

Please post back what you find

NEVER operate a set after it makes a loud pop. Only high voltage discharges can make such a sound. It is DANGEROUS to operate a set under those conditions. The chassis could be electrified or it could start a fire. Contact a qualified service technician.

I ran the Auto Scan. Before the scan reached 91%, I pressed the Menu button on my remote and all of the channels that it found locked in.

Easy way to find out is to use another source like dvd movie etc. If it does not freeze then it is cable signal issue, which is a common problem with digital channels freezing.

its the invertor board if you have sound/does it flash for a second when powered on then its that or a back lamp

your problem in in the mainboard very hard to find but try tops electronics in haverhill ma or shopjimmy.com
