SOURCE: What universal remote code do

The reality is that almost everyone ends up using two remotes. One to turn the tv on and off plus adjust the volume plus the second remote to change channels within cablevision.

Call cable vision and complain. They could upgrade your remote if they chose to so u could do it all on one remote. Hope this explanation helps you. Joe

The tv wont come on the green light just keep flashing


Power supply needs to be first checked:

some information:

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

I get only channel 2-14 on my TV. I have comcast with 200 channels and have 3 other tv with no problems on cable so it has to be I symphony TV


This can be due to that this TV does not have QAM tuner to get the free unscramble signals, this is the spec of the TV:
http://lcd-tv-info.blogspot.com/2011/01/isymphony-lc24ifh7pb-24-inch-1080p-lcd.html

You should look at the spec of the other TV to see if they are equip with QAM tuner.
