You may have power supply module problem or short circuits in the inverter board, those are the two areas you need to check.
Right now the 5vdc standby is working but nothing else.

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.

My samsung dlp turns on, then after 10-15 sec turns back off


It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

Tv lights blink, tv not turning on


HI, the fly back transformer has failed in your unit. this will occur if the dust level is high inside the set. the dust will settle on the cooper windings and, create an arch that will short out the entire power sector of this unit.

The fly back is usually the first to take the hit. replacing this will fix this issue.

My RCA D52W20 turn on with a blue screen and then turns off within 3 sec's. It goes off like someone has switched off the TV. The light blinks and goes off. Can anyone help


Your blue tube has a short. What you are seeing is the TV turning on and the blue tube going to full brightness. It then draws enough current that the television's protect circuits shut it down.

Need the full model number which should include a BYX or just YX followed by a number. Going off the D52W20BYX1 the blue tube would be part number 263049 which https://www.encompassparts.com still has a few for $220 before shipping.
