40 inch ktv model ltw40eh1b. When plugged in the light the blue light will come on but when I hit the power button I hear a multi note tone and nothing else will happen. I can unplug it and can go through the process but same result. I have heard that it may be the media board and also have heard that it may be the power supply. Tthe thing is I cannot find a wiring diagram or also where I may be able to purchase these items. Any help would be greatly appreciated. Thanks

Sony kdf60xbr950 Having the same problem with no picture. Green lights blinks first then the red lamp light. My first thought is the lamp. Then I had talked to a tech and he tried to tell me that its the balist or the power supply and likley not the bulb? Has anybody else been throught this and what was the outcome. This is the original bulb with only about 1000-1500 hours on it ? was working fine one day and the next this ?


The problem here with the lamp is it has an average 2,000 hour life--only way for a "tech" to know if it is the problem is to replace it.The ballast is the power supply for the lamp---lamp goes bad a lot more often than the ballast= sounds li ...

I have a Power Supply Unit in Westinghouse SK-26H240S TV. TV had no power prior to disassembly. This TV has the Delta DPS-210EP-2 power supply. I appear to have proper voltage on high side, but i am not getting 24v; 12v; 5v, and 5VSB on secondary side output. The Bridge Rectifier is putting out 53V DC. The filter caps have been replaced on PSU.

Hi In reference to Nec Model PX-42VM2A Power Supply Part Number PKG-1719 Transistor Q4 Defective Part Number on Transistor appears to be B1229 do you have a exact cross reference that will work for this part.My research indicates it may be 2SB1229 the case is TO 92 lead configuration B C E.I am finding it is very difficult finding this part.If possible would appreciate a diagram or a partial diagram of the power supply. Please Help.Thank You James Birdsall


James, \015\012\015\012Unfortunately, NEC does not make service manuals available to the general public in most cases. The B1229 is most likely the 2SB1229 as you suspect. Perhpas more important is to try and determine why the transisto ... NEC PlasmaSync PX-42VP2A 42 in. Television

Toshiba 40rv525rz shut off while playing xbox. When it shut off i could see a small white line on screen then went black. Tryed to unplug it for 5 minutes and would not turn back on.

Hi, Can anyone recognise or diagnose this problem we are having with our Samsung LA32A450 LCD TV? It wont power up, no power on lights. Switch on side of TV wont turn on. Remote wont power it up. This may be the key ..... My wife tells me that my 3yo was playing with the remote & the buttons on the side of the TV Would there be any strange combination of buttons pressed that could have rendered it useless? Could close proximity remote activation have caused anything?

Dynex 47 My Dynex TV stopped powering on. I was told it could be the power supply board cause the indicator light was not on red or turning green when you tried to turn the TV on. I installed a new power supply board, and i'm still not getting any picture or light indicator. What else could the problem be?


This is exactly why I tell people that when your set isn't working, you have to have it properly diagnosed. Chances are you have a defective main board. The power indication is an indication that you have standby power. However, the power indicator i ... Flat Panel Televisions

Hi I have a power problem, with my Sony RDR-HX717 DVD Recorder. I have no power at all in the display or anywhere else in my recorder. I suspect it could be the fuse, on the power supply board, which is a Newton Power NPS-51AP. The fuse is a T4AH-250V. My question is - what is the best way to replace this fuse, as it is in a closed fuse socket, which is not easy to open? Thx for any help. Fritz Diedrichsen

No power I have a LG 50PG20 Plasma. It does not have any power. I changed 5 capacitors that were bulging on the power supply board 10v and 50v. I tried to power it on with no results. I looked at all the capacitors on the other boards and they seem to be fine. Is there anything else I can look for that can solve this issue. Thanks


When the caps got real bad they may have taken another part on the power board---also see if any of the foil traces on the bottom of the board were damaged by the caps---some will actually leak a material that can eat the board foil off.Short ... LG Flat Panel Televisions
