Screen goes black but not off hps5033

Test your panel lamp voltage lines and see if they drop off when the screen goes black

also check the power cord wire coming from the back of the tv is loose from the tv side or perfect.

The power supply board has some electrolytic capacitors that have gone bad. Put a new power supply board in it. You can get it here : TV Parts Universal TV Stands DLP Chips ShopJimmy

It might also be a bad solder connection, short of checking voltages what I have done in this type of situation is with back off use a small fairly high speed fan - a hair dryer set to cool works, to cool areas of the boards inside to localize which board is causing this, with the set in failure, got it? it goes out cool it with a handheld hair dryer with air set to cool, when you find the spot where the problem is it will either instantly come back or try to.

Do it a few times to confirm which board is bad and locate a replacement board and swap it out.

If you have electronics experience - check the power supply and make sure you are getting the correct voltage to your inverter boards and main av board - also do you see any movement on the screen take a flashlight and shine on the screen - if you can see a dark image on the screen check inverter boards and power first.

Download software from the Phillips web site. Use a usb flashdrive to transfer the download to the TV. This worked well for us and our picture is better than ever.

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!

Check and make sure the software is updated on the set.

turn on tv, after a few minutes picture goes black, but still have sound. red light blinks 5 times,turn set off same thing happens when you turn set back on. some times it want do it for 10 min.
