This can be from your main board or your power supply unit. To test which one is bad simply try putting your volume up or down while the TV is on. If the volume changes it is most likely your power supply unit, If nothing happens then it is most likely your main unit. Both are available here: 1LG4B10Y11900 Z7GB Sanyo Power Supply Unit for DP58D33 1LG4B10Y117000 Z7GB Sanyo Main Board for DP58D33

If this is a standard CRT TV. The problem may be minor. You will have resolder the horizontal transformer (not the flyback transformer, although you may resolder this as well). You will also need to resolder the vertical IC. Do not over solder as to short pins here. And, if I remember from these older Sanyos...there may be a standing resistor or two (2 watts I think). This resistor needs resoldered. In any case inspect the board for any bad solder grounds. These will include the cracked rings on all transistors, capacitors, ICs etc. Also resolder the small board attached to the CRT. Becareful when you pull out the board to rework it. You must discharge the picture tube. See discharging picture tube on "You Tube". Thanks for asking me. Matt of Martins TV Repair.

    My mistake. This is flat screen LCD. Parts Runner is correct. Sometimes the inverter board is self powered and needs replaced. In this case I think the power supply proveds all the voltage to the screen. I saw the board Parts Runner is telling you about. The high voltage inverters are in the power supply. Yes, Parts runner is correct. Thanks for listening...again. Matt of Martins TV.

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://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. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I HAV a 58 inch Sanyo tv DP58D33 and my screen is black but when I flash a flashlight in a dark room while is on I can see the TV displays. What should I change to fix problem


a model 58D33 is a LCD screen not to be confused with an LED tv , aas LCD tv displays use a std fluorescent tube for its back lite source and yes they do burn out eventually , unfortunately these tubes are not a user changeable item and tv needs to be disassembled to install a new one

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
