SOURCE: WONT TURN ON

Most likely, the problem is a defective Main Processor Board. This is the board with the antenna, RCA and HDMI plugs. You cant repair or replace component parts on this board, so dont even try. You must replace the complete board. The TV says Sylvania, but it is a bloody Funia TV. Several years ago this foreign company bought out broke-azzz Sylvania . They are still carrying the Sylvania name since Sylvania was a popular TV name in the 70s. Every electronic company in the USA is now owned by the Chinese, so call Funai and order the part from them. Dont be surprise if they dont have a clue what the heck you asking for. America and all electronics have gone to the puddles. Do you know why? GREED.

SOURCE: There was a power surge and a loud pop and now the

A job for the technician on this one. I have only worked on several flat screen before, on my last days as an electronic technicians. Half of the ones I worked on was the power supply inside ir the problem was like this. Instruction on how to fix them would require me to write many pages on electronic theory so, I am very sorry It is almost impossible for me to help you on that. Be carefull where you take that tv to. some shop can't fix those. You may have to search your local area for someone who specialize in flat sreen HDTV. Well I hope I have shed a little light on the problem. Thanx for posting the problem.

SOURCE: Sylvania 6842THG won't turn on

I have been having the same issue. I unplug the TV for 10 minutes and it usually works fine. I moves all of my A/V plugs to a single power strip and that helped a lot. Since then, the TV went into protection mode only once in 2 weeks. Next, I will use a power strip that includes the cable protection.

Why is my sylvania lc260ss1 flatscreen in standby.


Try unplugging it from power for a while, 10-15 minutes, then plug it back in and try it again. If it still doesnt work then chances are the power supply inside needs repair. The most common problem with LCD tv's is failing capacitors in the power supply, they appear to have power and the standby light comes on but they just refuse to turn on.

Is the red light suppose to stay on when you turn off the tv with the remote?


Yes it is supposed to stay on. This is the standby light. The television still draws power as do many electronic devices when not turned on and when in standby. If you do not want the red light to stay on you will have to unplug the television.

Tele turned itself off, red light blinks 4 times then pauses and blinks 4 times again.


You can try unplugging it for a while and then plugging it back in, but according to the manual, the standby LED:
Lights up red when your TV is in PC power saving mode. If the LED blinks in red continuously, this may indicate the TV needs servicing.

My emerson tv standby light is on the power light flashes twice


Mine stayed in stanby mode and all I had to do was to switch the plug to a different outlet. The power strip it was on wasn't providing enough power. It worked fine for a month before I had a problem.

LG LCD TV Standby Light Flashing Red Continuously


I have had this same problem twice in the past 3 months. So far both times I've been able to get it back after a week or two. I'm not sure what works, but unplugging and detaching the antenna and cable and waiting a few days seems to be the key. In both instances, I unplugged it for a few days then plugged it in for a few days and repeated the processes until I eventually got the steady red led. Both times prior to the red led the led would flash red then green and make a clickiing noise for several hours before I was able to get it working again.

Red led stays on after turning off.


Aren't you talking about the standby led? cause that is perfectly normal... when it's on it means you can turn the TV on by remote, usualy it goes away when you turn the TV off manualy by pressing the OFF button on the set, but is this really your problem?
