Check your old board for bad capacitors. Mine had one bad capacitor. 470uf and 25volts
Hard to replace capacitor because the board is seal. But can done with some solder knowledge. Drill hole behind bad cap, 3/4 inch wide. desolder the old and replace with a same rating cap. Seal hole with tape and reinstall.
A common problem with samsung flat panel tv's is that the capacitors on the power supply fail.
You will need to remove the back and check the power supply pcb for puffed caps. To do this you will need to lay the tv face down on a cushioned surface and remove all the screws that secure the back of the tv. You will need a surface large enough to support the whole tv. This is to protect the panel. DO NOT place tv on surface where the front of the tv is not supported by the frame.
Remove the back of the tv and check for puffed caps on the power supply pcb. This is the board that the power cord is attached to.
If there are any puffed caps, you will need to replace them with equal or slightly higher valued caps.The value ratings are printed on the capacitors in mfd and voltage.
You will need a soldering iron to remove and replace them.
After reinstalling the power supply and before you put the back on, hook up a power cord to the tv and try turning it on. If you see a backlight come on, the tv is working. Try hitting the meny button and see if you have an on screen display. If you do put the back cover back on.
If tv doesn't power up, then the power supply pcb is probably bad. Try checking the voltage outputs from the connectors on the side of the pcb. Use a digital multimeter, connecting black lead to chassis ground and read lead to check voltage on the pins of the connectors. There should be voltage levels printed next to the connector on the pcb. Let me know if this helps you.
What is the complete model number? I assume this is a 32inch lcd. If it is then you need to check for puffed capacitors on the power supply pcb. If there are any you need to replace them with equal or slightly greater values. The values are printed on the capacitors in mfd and voltage.
To do this you need to lay the tv on a cushioned surface face down. The surface must be large enough to support the whole tv. This is to prevent damage to the panel.
Remove all screws securing back of tv, remove the back and check the power supply for puffed caps. The power supply pcb is the one with the power cord attached. If there are any they need to be replaced with a soldering iron. Let me know how this goes. Thank you
Magnavox has issues with puffed caps on the power supply. This sounds like its a 32 inch lcd tv. I tried searching for a service manual for this and can't find one. If it is an lcd you need to look at the capacitors on the power supply. If they are puffed up, you will need to replace them with equal or slightly larger valued capacitors. The capacitor values are mfd and voltage printed on the capacitors themselves. You will need a soldering iron to replace them. Lay the tv, if it is an lcd, on a flat surface cushioned by a blanket. Make sure the surface is large enough to support the tv frame, as you don't want to cause damage to the panel. remove the back of the tv. There are numerous screws, and once the back is off, check the power supply pcb for puffed caps. This is the board with the power cord attached. I know in magnavox tv there is a cage covering the power supply, so remove any connectors because you will have to flip the cage housing the power supply to get to the caps. If you feel confident, give it a try. Let me know how it goes
How old is the tv? This is a power supply symptom. You will need to take the back of the tv off and check for puffed capacitors on the power pcb. This is the board where the power cord plugs into. Lay tv face down on a cushioned surface large enough to support the tv frame. You do not want to damage the panel. Then remove the back. If there are puffed capacitors, replace them with equal or slightly higher valued capacitors. The value rating for capacitors are mf and voltage, printed on the capacitors. If they look good, you will need to check the dc voltage output from the pcb usually about three connectors in the same area. One way or another, it is a power supply problem, usually corrected by replacing caps, but if that doesn't work, you will need to replace power pcb
TO ALL YOU TOSHIBA 42HPX95 I FOUND THE REAL PROBLEM ON THESE TV'S IM NOT SAYING THIS IS THE SOLUTION TO ALL TOSHIBA PROBLEMES BUT I GOT TOO OF THESE AND MANAGED TO REPAIRE THEM FOR ALMOST NOTHING "!!!!!' THE DEFECTIVE PCB IS THE SIRIEN PCB OR WHAT WE COULD CALL ACCESORY PCB THE PCB IS SHORT CREATING A OVER LOAD CONDITION AND THE PROTECT SYSTEM DOES ITS JOB I AM INCLUDING TWO PICTURES THE FIRST ONE WHATS THE ACCESORY PCB AND THE SECOND WHAT CONNECTER TO DISCONNECT IN THE SECONDARY SMPS WHAT YOU HAVE TO KNOW IS THAT YOUR PIP WILL PROBABLY NOT FONCTION ANY MORE YOUR PCCARD READER WITCH IS TOTALLY OUT OF DATE AND OUT OF DATE COMMUNICATION PROTOCOLS LIKE IEEE 1394
AND G-LINK AND MAYBE THE CARD READER ON THE SIDE IF NONE OF THESE ACCESSORYS ARE VIMPORTANT FOR YOU WELL YOUR TV IS FIXED IF THE ARE SIMPLY REPLACE PCB THE NUMBER OF THE PCB IS PD2266 I FOUND ONE FOE 120 DOLLARS AT SHOP JIMMY ALSO IF YOU MANAGE OUT WELL WITH A OHM METER HERES A TEST YOU CAN DO DISCONNECT TV FROM POWER DISCONNECT CONNECTER PJ63 ON ACCESSORY PCB WITC OHM METER TEST BETWEEN GROUND PIN 2 AND PIN 1 DO THIS ALSO WITH PIN 3 AND 4 THERE MUST BE NO CONTINUTY WITH GROUND ! HOPE THIS WILL HELP
