Need circuit diagram for pd2171 23590258B power supply

Check plug first the one you plug in wall if there is a small black box at point were you plug in ,there is a transformer in there sometimes they short out .Check with multi meter if it is good then try schematic or Circuit diagram

JAMES THERE SHOULD BE A SITE ON THE INTERNET WHERE YOU COULD CALL SANSUNG CUSTOMER SUPPORT TAKE A LOOK!

Usually a clicking noise when trying to start a TV indicates a short. You are getting power to the TV but the ON/OFF switch is defective. Generally the ON/OFF switch is built onto the Circuit Board. It sounds like the TV may have been a victim of a Power Surge that damaged the circuit Board. Always use a UPS and NOT a Power Surge Strip. The Battery Backup UPS is the best protection and my customers never have a burn-out problem. Regards [email protected]

what board did you asking the power supply board or the inverter board for back light.

Probably not too much help right now, but you can get a small device online for just that purpose. Try shopping for "computer power supply tester" Less than $5 including shipping.

Many people buy parts items from ebay to fix their own defective units. Just read the problems of the parts item, then you can decide if the parts you need is available from the broken unit?

I would also have liked to have had a schematic diagram for my ECHOSTAR 450w ATX power supply.

Not having one though, I have replaced two capacitors (one with a bulging top) and another with a leaking top, three rectifiers (two shorted and the third had a cracked case), and have ordered transistor Q1 (also shorted). Will also need to repair trace damage on the bottom of the circuit board. Other components check out OK so I hope it will be working again after the transistor arrives Monday. I need the -5v this one supplies to get my old computer running so I can retrieve last year's tax info.

I'm afraid I cannot comply with your wishes, as there are copyright laws governing this, for one. (For existing circuitry)

Two, there is the liability issue. Take for example that I design the requested circuit, give it to you freely, and you or someone in your group is injured using my circuit.

Will state that this is a basic circuit design. I believe that if you 5 put your minds together, you can build this circuit.

hi friend ,

u can construct ur own power supply board
this would be less expensive and u can gain experience
u just need a transformer,4 diodes,some capacitors
it's fun to play with these things and u will enjoy it

u can see the circuit diagram in
www.circuitstoday.com

i think this would be interesting

thank u for using fixya

regards,
sivaranjini

Diagrams i am sure as you know are not always easy to come by, at least for free. I see that there are available boards online and a company that will rebuild this model of power board for you in UK. ohmsupplies.co.uk is where it is at. looks like $80
