Why does it turn from blue to black after 10 sec.?

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electro-medical.blogspot.com/
http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced.

I have a gv47l fhdtv10a lcd. it made a loud pop and went blank. i replaced the fuse on the power board. the tv will power on but the screen stays black and the tv will not power off unless you unplug it....

Something on the power supply board has failed. One or several of the voltages is bad and you don't have full control, no off, no screen voltage, etc. Unless you can troubleshoot switching power supplies, its best left to a repair shop.

The screen went black the litte red lite blinks...

the light indicates an internal electronic fault with your set
projection TV`s have integrated protection circuits
built into the circuit design, these circuits turn the
power off automatically when a fault has bin detected this
is in order to prevent a more costly repair, these circuits monitor
power supply , vertical and horizontal deflection
over voltage, or x ray, and also faults with convergence circuits.
Diagnosing these faults require test equipment and a good knowledge of
electronic repair techniques, and also a repair manual.

Ds lite flashes on but fuses are ok

One or both your screens have blown.

Try removing the motherboard from the screens and attach the battery the green light should turn on and stay on.

Now attach the lower screen and turn on. If the screen is ok the screen and green light will flash and then turn off. (if the screen doesn't flash the bottom screen is you're problem and will have to be replaced)

If this happens the problem is then you're top screen which you will have to replace.

Sounds like a failed power board inside the TV, not the power supply. Unfortunately this is a very difficult repair, and unless you are an electrician I would not recommend attempting it. You will need to contact a local TV repair person in your area. If you think it may still be under warranty please contact the manufacturer to file an RMA. If you happened to purchase the TV with a major credit card (not a debit card) there is a good chance it may still be under the free extended warranty most credit cards place on electronics. Please contact your credit card company to inquire if they do this, and they will be able to file the claim and get you a refund for the TV.

So sorry that I don't have better news but it is definitely a power issue internally.

Thanks
Tim

Please consider coming back to your question here and changing your rating to 4 thumbs up. It is extremely important that you do so, it actually hurts my account having just the 3 thumbs up. Thank you Tim
