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

I have Samsung UN46B8000XFXZA LED TV. After power surge it will not come on. Plugging it in causes the blue power up light to come on for one second. The relay on the power supply (BN44-00270A) begins to click. The screen does not come on. All appears dead except for the clicking of the relay on the PS board ever few seconds.rnIf I unplug the connector from the power supply to the Main Unit Board (BN94-02661E) and apply 110v, the screen backlight comes on and there is no relay clicking.

Yes based on your testing it appears that the power supply is at fault solely and you can opt to attempt a repair or replace it altogether. Unfortunately you will not be certain that the main board does not also need to be replaced until you have rep ... Samsung Flat Panel Televisions

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. All it was doing was flashing the lit toshiba emblem up and nothing else! Talked to a couple of people and they told me it sounds like a power supply problem! So opened up the tv and saw that the power supply had a burnt resistor and there was also sut on the backlight inverter so i ordered a new power supply and in

Main Board? Had issues for years, where I had to unplug once in order to get the tv to turn on. Then one day, it would not turn on. The TV shows a quick lightening of the screen like it is going to turn on, but nothing appears. It also clicks once or twice. Took to a repair shop and they diagnosed with main board failure and refused to fix due to lack of parts. Do you think it is the main board and where would I find one? I am pretty handy, do you think I could DIYthis job?


The fault must be due to a main board fault. Generally, it will be impossible to get this board repaired. A replacement must be done. Most of the parts in this board are not available by local electronic spare part market. After power ON, there sh ... Proscan 47LB45H 47 in. LCD TV

I have a Sharp LC-19DV12U with a defective D501 labeled 10E241. It is located on the power supply pcb connected across the 120v input to the board. The board does appear to use conventional identifiers (c=capacitor, r=resistor, t=transformer) so I would expect it to be a diode although in fact it looks like a ceramic disc capacitor. Unfortunately, I don't have a tech manual or a parts list. Can anyone help with a part number?

Power Surge After house power went out and came on 20 seconds later, my Pioneer would not power back up. It has two LEDs - the blue "on" LED flashes 12 times on, pauses, and repeats the sequence over and over. I tried powering down from the switch and even removing AC power entirely for a couple minutes. The best it would do is to go thru it's normal power up sequence, show a "starting up - please wait" screen for a couple minutes, and then shutting back down with the blue LED flashing.

I have a Samsung LN40A550P3FXZA that is giving me problems. When I first started noticing problems I would turn the TV on and I would hear the power-up sound, the backlight would come on and then the red LED would flash a few times then the backlight would go off and it would repeat (power-up sound---backlight on---LED flash---backlight off). It would do this several times. Sometimes I would be able to get picture if I hit the source button on the side of the TV when the backlight first came

Like yourself i have replaced 4 x 1000uF 10v caps (high temp) as the were distorted at the top. However my Samsung LE40R8 is exhibiting the same problem......Clicking noise and red LED going on and off. I was convinced this would cure the fault, having a basic knowledge of switch mode power supplies.

I have a 2002 Mitsubishi WS 65908, that was damaged last week during a power surge. Smoke was coming from the unit and I unplugged it immediately when a I heard a crackling noise and saw the smoke. Now the unit will not turn on. Please tell me if the unit can be repaired and either way, please tell me what parts may have been damaged. How much would this cost to repair?


From what it sounds it has been hit pretty hard, and it probably is not repairable, you might want to check and see if your home owners insurance will cover the power surge , most of them will, and have wrote off. ... Mitsubishi WS-65807 65" Rear Projection Television

My Sanyo DP26648 is completely dead. If I turn it on, the power LED comes on for about 5 seconds then goes out. I can repeat this twice, and then the power LED won't even come on. Unplugging and then replugging the TV will once again allow the Power LED to come on for 3 cycles in attempting to turn on the TV. I guess replugging in the TV allows a capacitor to recharge and power the LED? Is this TV repairable or is it time to replace it?

Recently my benq mp620p projector stop working. When I connect the power cord the power button lights up green and the power led orange as usually. When I push the power button, it starts to blink in green, the filter wheel starts to spin and the lamp starts to warm up with some light comming out. Few seconds after, the fans start, the power led becomes solid green and the lamps goes of. I can't do anything else since that other than unplug the power cord. No response to any button.

I'm assuming that you have checked the bulb and it appears ok. Either the inverter/ ballast board has a fault or , much more likely, the control board is no longer capable of finishing the loading of the firmware. This is usually caused by the failur ... Flat Panel Televisions

Okay, so my Panasonic PT-43LC14 went black in mid show last night. The bulb is approximately 18 months old. The LED indicators upon Power On are; Power LED blinks green for approximately 70 seconds; Then the Power LED switches to Red Blink, and the LAMP indicator blinks once every 5 seconds. Service manual indicates this means lamp or ballast issue. I've inspected the lamp, and it doesn't appear to be burned out. I've disassembled the TV and check the ballast for visual issues and see none.


Check the bulb again and look at the root of where the main stem comes out inside and be sure you don't see any bubble like appearence around the stem at the bottom there. If you do see this then the bulb is bad. Otherwise try this: Hold volume do ... Panasonic PT-43LC14 43" Rear Projection HDTV

I have a vizio vp50 hdtv20a. A while back we turned it on no picture and it started to smoke. After reading a little about it I decided to take off back panel and see if I could locate burnt part. Could not locate burnt part so repair man came and we plugged in set with back off and turned set on. Resisters on y main board started to get red and start to smoke. So we figured it was a bad y main board. Repair man said he would order part and get back with us in couple days. Three weeks later
