Question about Akai LCT3201AD 32 in. LCD Television

1 Answer

AKAI PDP4225M HAS RED LIGHT BUT WILL NOT POWER ON.

I've pulled the power supply board but need to obtain schematic to properly repair. The fuse is not blown.Found bad 5.6 ohm 1/2 watt resistor at R001 and replaced.Relay at RL002 activated when power switch was turn on then immediately turned off.Checked resistor again,it was bad again.I'm sure it is a cap issue.Have you diagnosed this problem before? If so, do you know which caps to replace?(Power supply MPF7410 A)

Akai lct2721ad wont turn on red light in on


Whn you try to power it up does it attempt to power on before going red or does it just stay red? If it just stays red then its definitely a case of faulty power supply board. The easies way to resolve this problem would be to replace the power supply board, which can be obtained for about 50-75$ from shopjimmy.com. So let me know if you wish to fix it yourself

My akai pdp4225m 42inch plasma went out. when i turn it on i dont get the blue akai splash screen. just black. any ideas on what part to order?


You may have one or two problems, the power supply has failed or the Y-Sustain board has failed also. The more common problem is the Y-Substain board if fails the most in plasma television, next comes the power supply then the X-substain board, My best solution for you is to check the power supply first and consider ordering the Y-Board also, the PS is usually the center board and the Y-Board is to the left of it. The X- Board is on the right side..
