Question about Zenith L20V36 20.1 in. EDTV-Ready LCD Television

1 Answer

Sounds great. Can't see diddly

I got this lcd tv just to see if I could repair it. The person I got it from has had it since it was new. He sent it back to Sears and they reported it needed a new "memory card". I can't find anything anywhere about any sort of memory card in this tv. So here's what it's doing. I've tried hooking it up to the regular antenna input. As well by rca audio/video cable. Same result. Great sound. No picture. I get multi-colored horizontal lines that move constantly similiar to static. And an occasional line will scroll thru moving from top to bottom (similiar to a refresh on a regular crt) that scrambles these lines up but otherwise has no effect. There's no visible picture. Any help would be appreciated. Thank you

What to do when you have a cracked LCD, LED or Plasma TV

Spending a ton of money on a new TV is the norm these days. Unfortunately televisions are not made like they used to be. Flat panel LCD, LED and Plasma TVs are very fragile. The picture area can be cracked by even light objects hitting the TV.

Once the picture is cracked there is no way to repair it. It needs to be replaced. TV manufacturers purchase LCD, LED and Plasma screens in large quanities and get a great price. When your local repair shop has to purchase a single replacement unit, you will often find it is as expensive if not more expensive then a new TV (if its even avaliable) when you factor in the labor costs. Usually you are better off replacing the TV with a brand new set the next time a good sale comes up then have it repaired.

You would think the TV's warranty or extended warranty you purchased would cover a cracked screen. Alas.. they don't. Every warranty I have ever read does not cover accidental damage. As soon as the repair person sees the screen is cracked, they will tell you the warranty does not cover it and you are out of luck.

While there isn't much hope for repairing your current TV, you can take some simple steps to protect your new TV from damage.

1. Mount the TV on the wall. Its a lot harder for little kids to hit the TV or throw something at the TV when it is mounted on the wall vs sitting on a stand.

2. Explain to the family how fragile the TV is. While this might seem obvious.. kids do know things until they are taught.

3. Wear the wrist strap while playing video games as recommended!

4. Pickup a tv screen protector from a company like TV Armor. They are designed to provide impact protection for the TV without affecting the picture.

Following these simple steps can keep you enjoying your new TV for many years to come even if you do have a budding baseball player at home.

We were playing playstation last night on our tv, then afterwards we watched a movie until about 1:30 a.m. Turned it off and went to bed. When we turned it on this morning there is sound but the screen is...

That sounds like your back light has gone out. Either the back light or it's power supply failed. If you turn it on and get close a bit to the side you should see a ghost image. That will confirm it is a back light instead of a video section problem. A lcd type display creates the images on the lcd panel, but it doesn't generate any light. The backlight shines through and illuminates the images. Very much like a slide or move projector.

The repair cost really varies from model to model. The actual backlight can be repaired for under $150 in most cases. How ever if the power section is part of the main tv board then the entire main board needs to be replaced. That board on other sim sized tv's can run over $450. This is covered under warranty so the first thing you need to do is check if you have any warranty either extended store or the oem warranty. Then contact the store you purchased or go through the Phillips support to find your local repair depot and get ti sent in. If you do not have warranty then you have to be careful as you are paying for this. You need to get a estimate. A repair depot will have a very good idea of the repair cost.You should also have an idea of what a replacement tv is worth. Once you know how much the repair cost is you can then judge if it is worth fixing or if you should get a new tv. A new tv has a new warranty while your repaired tv will not. So if the repair gets too high you are better off replacing and not having any worries.

As a home theatre sales person, i can say that i have had my fare share of dealings with new TV manufacturers. Although sometimes what i am about to say sounds a little abrasive, it seems as though youve fallen victim to the newly developing 'disposibility' trending in electronics manufacturing. You may have already tried using the on board controls, and if that works, try an advanced learning remote control to regain control of the functions. if the onboard controls arent working either, you could try to send it in for repair if its under warrenty, or look at buying a new flat panel. The avg repair cost on an lcd is 300-600 for parts and labor, there are many 1080p 40-42 in the 600-800 range.
