SOURCE: AKAI 32" LCD HDTV WILL NOT TURN ON

The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com

Your power supply is faulty I'm afraid. Unless you have soldering skills, I am afraid you will need to contact a professional TV repair person. If you feel confident to try the repair, contact me with the model number, and I will let you know what components you need to change

My Samsung Tv will not turn on and I have blinking red standby light. Model code: PS43D450A2WXXU. I have take the back of it but unable to locate the issue. Any ideas? Thanks in advance


If you are getting a red blinking light, this usually means that you need a new power PCB. The circuit board that the power cord connects to is probably gone bad.

Sound doesn't work in HDMI mode, just picture. I tried buying a new HDMI cord but that didn't work either. Then one night the TV just turned off and now it won't turn back on.


Likely not related but HDMI does not like being connected if either unit is plugged in or powered up.

As to the TV let me know the brand and model number and what if any lights at all come on when you plug it in etc.

My Sony wega tv won't turn on goes into standby red light blinks 10 times then shuts off?


Look at the owner manual as the 10 blinks is a error code or Google the model number to locate that information--Sony error codes are general and often misleading.

I would if looking at the set inspect the lamp first.

My LG 32LD320 won't turn on. I have no standby light and have even tried changing the fuse. Help please!


If total dead best way is to follow the AC voltage from power cord inside the set to see where voltage is lost.

Also , were you having any problems having to turn set on several times to get it on?

Samsung T220hd won't turn back on from standby


Power up issues on the T220HD monitor are caused by a failure of the capacitors on the IP-49135b power supply board that this unit uses. The repair is easy, you just need to replace the 7 failed capacitors and the unit should be as good as new. Here is a link to some information showing what needs to be replaced to repair the power supply board.

I hope this helps.

Samsung le32b450cw wont go from standby to on


Hi.

Unfortunately I won't bring good news.

Your TV is in forced standby. The state is also called "protection" and indicates a special mode tat kicks in when an internal fault such as a short (big power draw) or a wrong voltage is detected. When that happens the protection circuit to force TV PSU to shut down all voltages apart the +5VDC line that keeps TV in standby.

All you can do is disconnecting the power cord, checking if there is a fuse built in the power cord, replacing fuse and connecting back after about 30 minutes (that allows power drain). If the TV does not work there are faulty internal parts that need replacement.

If now the TV does not start at all, and not even the standby light is on, then the problem is usually the PSU. The part must be tested and eventually replaced.

Yep, I can help but I am afraid that I won't be able to bring totally good news.

The TV is in forced standby also called "protection". Protection kicks in when an internal fault such as a short (big power draw) or a wrong voltage is detected. The click comes from a relay activated by the protection circuit to force TV to shut down.

All you can do is disconnecting the power cord, checking if there is a fuse built in the power cord, replacing fuse and connecting back after about 30 minutes (that allows power drain). If the TV does not work there are faulty internal parts that need replacement.
