Question about Philips Televison & Video

1 Answer

Philips 19pfls422d/27 LCD tv. Turns on for a few seconds, everything is great, but then shuts off (power light goes from blue on to yellow standby) Was told it's the power supply board, but I can't find any place that carries it. If I had a part number I could probably get it

    looks like a bad IC on the power supply board (smoke traces) did find a part number for the whole board, and new one is only $43

  • archemedes74 Jul 28, 2010

    there was a part number on the board, and I just googled it, shopjimmy had it for the best price, but the highest was $60 from mouser

It may have gone into protection shut down mode because it sensing overload by such thing as the backlight inverter board. You may want to inspect the power supply module first for bad DC filter caps, then check for shorts in the inverter board.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

    That is really good price, I have been Google the web and did not find the power supply for your TV. Where did you find it at?

TV turns on for a split second then back to standyby


i think your capacitor is blown, do a google search for insignia, lcd, capacitor...
you can buy another one for about $2 but its a pain to install, you can also instead buy a new powerboard for about $80, its an east install and you wont blow more capacitors
