My 40 inch flat screen has a spider web across the whole screen but nothing elses is wrong with it is it fixable ?

you have two options.........one......you can find a repairman to replace the screen.......vs..........you can toss and buy a replacement. You will have to weigh your options based on cost.

It will be expensive and time consuming, but it can be done. There are many web sites that sell replacement screens. Just google TV replacement screens. You should download the service manual for your TV from Sharp's website before attempting to do the repair.

Yes it's cracked inside and there is no fix for a cracked screen, the panel will cost more than the tv new. It's not worth it, verify at vancebaldwin.com

Not fixable or worth fixing.The LCD screen panel is broken or damage,will cost the same to replaced the LCD screen same as a new tv.The LCD screen panels or any screen panels for that matter.The tv screen panels are limited produced by the the tvs corporations.Tvs are damages or boken screen panels are only can be salvage for it electronic boards for parts,not worth as a whole tv anymore.

only solution is replacing entire screens. very expensive, try finding manufacturer on internet.

If the main PCB is not cracked too bad, it should not be expensive to repair. You have lost vertical deflection causing the flat line.There may be a crack at the flyback, where the vertical IC gets its operating voltage, or a crack at the pins of the vertical IC itself.

Unplug tv first Usually you can pop the front screen off the set. There may be two hidden catches depending on the model. You may want to use two people for this. Once the screen is off removed the spider web and clean the back mirror with some windex, don't clean the inside of screen with any cleaner. Replace carefully the screen making sure it clicks back correctly

I know my response is a while after you asked, but to clean the inside of the tv case is pretty simple.

Remove the bottom speaker cover...on this model you just pull it off. There is no clips or screws.

Once the speaker cover is off you will see the bottom of the screen, there is 4-5 screws on the bottom on each side....I think 4 in the gray plastic and 1 in a black metal strap. With all of those screws out pull out SLIGHTLY on the screen and push up. The top is held in with a down force clamp and you are just popping it out of that....It will pop back in once you are done.

Now clean the back side of the screen, the mirror and CAREFULLY dust off the lenses. I myself did not want to use any cleaners (to avoid streaking) so I used a new microfiber dusting cloth. My picture became brighter and the "crack" that I thought I had was just a dust web....

Hope this helps and good luck

If you have not yet fixed this and haven't trashed the set I may have a solution.

I have a 50HP66 that has a good screen but bad sustain boards.

I will buy the boards from you...Easy to remove. Then you can use that money to buy a new TV.

Fixing a cracked screen is not practical. IE. Replacing the whole screen.

These sets are made to be sent to the land fill when the warranty is up.

Maybe we should have our lawmakers force companies to have minimum warranties for large toxic products that end up in the trash. Then they might make them last more than a year.

physical damage is probably not covered under warranty - check your owner's manual and call customer service - they will advise you [dxh]
