Fault in the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

I have an xbox 360, but i have a ps3 connect to the tv via hdmi. i swapped the hdmi cable to the xbox and powered on. i had all the cables in the correct position, the correct av selected on the tv, but...


Have you tried disconnecting the HDMI cable from both the TV and the console and then trying to reconnect?

Y+RT does not reset controllers for the Xbox 360, so not sure what you are attempting there?

What type of TV do you have? It appears the issue is with either your cable or the TV seeing that you are having the same issue with both your PS3 and Xbox 360.

I still think your first step should be to disconnect all cables from both ends and reconnect. (with poer off of all sytems of course) If this doesn't solve your issue then submit further information on your setup such as TV make and model and I can research other possibilities.

Battery won't fully charge. Max charge seems to be slowly going down. First noticed charging light coming on intermittently but battery only reached about 93%. 4 days later and the max charging seems to...


It seems that the issues is with the battery itself, not the cppu.

To double check, you can do the following:

1. Disconnect adapter and run battery completely dead.
2. Reconnect adapter and let charge for at leasst 12 hours OR until battery displays 100% charge.

If it still won't charge to 100%, then you know for sure the battery is defective/worn out..
If you want to know more about this, look on wikipedia for: "Laptop Battery Lifespan" or "Laptop Battery Memory Charging".

But I'd say it's safe to assume that it's time for a new replacement battery for your Notebook PC.

Hope this helps!

Picture on 36 inch toshiba tv out


I had the same problem on my 61" RCA TV... The switch for the power/channel changing buttons seems to be a faulty product... However if you are a little technical you can open up the front of the TV and disconnect the button panel from the tv and just use the remote to operate it.

Hitachi 32LD8700 - TV won't turn on although has power


The general problem with LCD type TV's is that the power supply fails. They are very sophisticated designs that are difficult to troubleshoot and generally best to just replace the module, but sometimes there is visible damage in some of the electrolytic capacitors (visibly bulged) and high voltage rated parts can be substituted.
