I have a Philips 42PFL7422D/37 42-Inch that went out a few weeks ago. After some research i figured it was the power supply board, not it. I knew it had fried some caps somewhere, replaced the master and slave inverter boards and Shazam! it worked perfect. However, when moving the set back into my living room I bummped the screen on the corner of the coffee table and cracked it.

Hi, can you help me with this TV please. Hi, I have a Olevia 232-T11 LCD TV. First my TV wouldn't turn and the blue light just stayed on. I replaced the power supply board and now my TV turns on and the screen lights up but I get no picture or sound. The slave backlight inverter board has a blue light when you turn the TV on but goes away shortly after. The screen stays on but I have no sound or can't control the channel, volume or source button. Please help.

Vizio GV47L...when i turn on the tv, the screen stays black. The vizio light turns white and it makes the click noise like normal but after a minute of it doing nothing the light turns back to amber. I can turn it on and off using my remote. I read other problems where people had to unplug there tv to turn it off. Mine will turn off. Would the problem be the power supply or the motherboard. The slave inverter was making a squeeling noise and i replaced it like 2 months ago.

I have a Samsung LN46A530 46" LCD TV. Lost my backlight and wondering if the two wire connectors feeding the R and L inverters is where I would meter for power, and if not what are these for ? Or is it the ribbon cable on the top left (it's pin ids are 1. 12v_cold, 2.FB, 3.FB, 4.GND, 5.GND, 6.LD, 7.LD). Would this TV use 12 V to power the inverters ??. The inverter enable is on (5V), so I assume it is either the pwr supply or the master inverter.

I got a Sony Bravia KDL-40WL135. Blank screen. There's two LED lights: red standby and green power light. When I turn on the TV, green led comes on, then after about 30 seconds red led blinks once, then green resumes. The green led stays solid. I think that's a SONY error code, I tried to look it up but can't find anything useful. I have replaced the power supply, AU board, backlight inverter, logical board, and the second power supply board. Any suggestions? I haven't checked the t-con bo

Hi, I bought a Vizio L32 HDTV10A that didn't power-up. There were charred components on the power board (an 8-pin IC with heatsink and 2 resistors). I replaced the power board, and the power LED then turned on (yellow) when power was applied. When the ON button is pressed, the power LED turns green for roughly 8 seconds and then the power LED turns yellow again. Nothing else happens. I checked many components (fuses, capacitor ESR, diodes, etc) on the main board and the master and slave inver

DP46849 Sanyo. I have checked all of fixya for solutions. I hane no sound or screen but have a green light when turned on. It will flash as if it is in protect mode. I have checked voltage and there seems to be 5v, 12v and 15v as indicated on power supply. I cannot find a 24v to read from but I did pull the master inverter to see if I had sound. Still the green light flashes and no sound. I suspect power supply only because when it is turned off I hear a high pitched whistle that slowly goes on

I think I shorted out the power supply board on my Onkyo HT-R667. I was replacing some the capacitors to repair a hdmi switching issue. I was testing the repair with the top cover off. While it was powered on I accidentally touched the metal top to the top of the power supply board CMKM-P3X. There was a spark and the unit turned off. It won't turn back on. No lights. Can it be fixed or can I purchase a replacement board if this is even the issue. Thanks

When power supply to TV exceeds 224V the TV switch off. It then tries to switch "on" again and will do so until the power supply to TV is lower than 224V. I ran a AC DC regulater to keep power output to TV as close to 220V. Then TV plays perfect. Aventually I unplug TV and go to bed. I have tried UPS's as well. Same problem. I think power supply unit in TV is damaged due to power surges. I replaced this 2 year old TV with a new one. Costly excercise. I still belive this TV can be fixed.
