1. Did you try to call LG/Zenith customer support and see if they can help you? If not find your nearest LG/Zenith service center (not Best Buy) preferably a small service shop to see if they have a service remote to unlock it

A cablecard is the size of a credit card use to view or record digital cable channels on a digital recorder,personal computers and tv s without the use of outside equipment like (stb) set top box provided by your cable company, below is a picture of one hope this helps.

you trouble on the cpu unit. try reheating it with hot air.

what kind of remote???most remotes show you a way or else give you codes for a majority of tv sets.vcr,cableboxes and other equip,reread the manual that came with the universal remote.it should explain all possibilities

if it comes to a replace ment board that is a fair price. matter of fact if you purchase the board over the web rather than a electronics supply shop locally you are wasy ahead of the curve. my advice is however if you have to ask how to replace the board you should not attempt the replacement your self. you should always be safe when working with electronics wether they be plugged in or not. often times even unplugged the unit wil;l still store a charge in it's capacitors. also if not careful static shock can damage other componants in the unit. find a friend to help you or take to a good repair shop.

Well, the green light blink for a while and solid green, but still no screen, no audio. Search the Web and someone suggested to replace Power Supply Board which will fix the problem. Again, search the Web and came out with Power Supply Board. LG Electronics/Zenith 'Power Supply Assembl' with $124.95 from PartStore.com. Is it the right solution? Do I have to replace entire Assembly Board? not just replacing some fuse? Any cheaper way to do? If I have to replce PSA board, any suggestion to how? Comment posted on Apr 22, 2009 I have a basic knowledge of electric and electronics, such as rewiring entire house for renovation and assemble entire computer from scratch.
Actually, the TV belongs to my father and the problem that I stated was based on what he told me.
So the question is based on the symptom that I posted, how sure are you that the problem is the Power Supply Board?
Is it good to order PSB? Comment posted on Apr 23, 2009 Purchased 2 and half years ago. Expired one year warranty. Comment posted on Apr 23, 2009 Zohail,
This is LCD TV.
There is no problem with the wall socket nor current.
I put other appliances on same wall socket and worked.
It has to be internal problem.
As I mentioned on the main post, there was a 'pop' sound while watching and TV went dead.
Turn on remote control, there is blink green light and then green stays on, but no sound, no screen.
Turn off remote control, light turns red. Comment posted on May 14, 2009 I fixed the TV.
Orderd power supply board which cost me $136.51 total.
Replacing was simple.
Just removed the rear panel cover then electronic board housing cover.
Took power supply board with all the connector cables and replaced with new one.
Problem was a transformer connector which got burned and blow up the plastic cover.
But no problem with fuse and capacitors.

Thanks all for advises.

Whats the model number of your Zenith and I will try to locate a owners manual for you.

If the LCD light on your Zenith CD/DVD duplicator is on but it is not showing as "ready," it is possible that there is an issue with the duplicator's internal components or settings. Here are a few troubleshooting steps you can take to try and resolve the issue: Check the disc trays: Make sure that all of the disc trays are closed properly and that there are no discs stuck inside the duplicator. If a tray is open or a disc is stuck, the duplicator will not be able to operate properly. Check the power source: Make sure that the duplicator is plugged into a working power source and that the power cable is securely connected to the duplicator. If the power source is not providing enough power, the duplicator may not be able to operate. Check the settings: Check the duplicator's settings to ensure that it is set up correctly for the type of disc you are trying to duplicate. For example, if you are trying to duplicate a DVD, make sure that the duplicator is set to duplicate DVDs and not CDs. Reset the duplicator: Try resetting the duplicator by unplugging it from the power source for a few minutes, then plugging it back in and turning it on. This can sometimes resolve minor issues with the duplicator's internal components. If none of these steps resolve the issue, it is possible that there is a more serious issue with the duplicator's hardware or software. In this case, it may be best to contact Zenith customer support or a professional technician for further assistance.
