Main board in TV went out and they want 375.00 to fix it. You can turn it on and it is fine with cable but you can not access the menu, volumn, to adjust anything and it is stuck on about a level 4 volumn. Can I disconnect the internal speakers and just possible use a receiver to get sound?
replace the amall EEPROM. typically it has the part number format 24Cxx and is very cheep.
if that doesn't help, then check the price of the main logic IC on the board. if the price of the IC is comparable with the price of a new board, you may decide whether to put a new board or not,
but i think it's always better to fix the existing board rather than putting a cheap crappy chinese board. those chinese boards are unsafe and prone to failure.. and the picture quality is usually bad.

Fault with 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. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis.
It could be the power or main board that is giving issues...if your able pull the back off and look for a pin on connector marked PSON or PON...that is line that tells the power board to come out of sleeping and go to work, you should see a change in the voltage when the on button is pushed, if you do then the main is doing its work and its the main if you don't see a voltage change then chances are its the power board
I had the same problem, i took it to a tv repair shop and the said it would be 3-$400 to fix so i just bought a new one but the repair man said the the main board the one with all the inputs and the power supply were bad. U can buy the main board for about $150 and fix it ur self... bth the power supply also cost about $150 as well but i would replace the main board first and see if that fixes ur prob
The main power supply will be the first place to check. You should have at least the standby 5vdc, which is used for the main board, when the power switch is activated, the main board will send out the signal to turn on the main power supply sections to power up the rest of the set. Look for simple thing like blown fuse or bad capacitors. Learn about what bad capacitors can do. http://en.wikipedia.org/wiki/Capacitor_plague
Fix for me: Unplug TV. Trace cables from on/off switch to main circuit board. I unplugged the cable at that point to eliminate the the on/off button and remote control sensor. Applied power to the TV and my TV stopped cycling on/off so I figured the problem was probably not on the main circuit board but with the push button/ remote control sensor board. I again removed power from the TV and plugged the cable back in to the main circuit board. I then applied power back to my TV to verify my symptom, but when I did this, the TV worked fine again.
Many times resetting circuit board connectors will clear electrical problems.
I recently bought an ILO 32 HDTV with the same problem. I searched every site I could find for a solution. I finally found someone that gave me the direction to replace the Main Board for the TV. This is the board that you can plug your exteranl devices into, computer, dvd, HDMI etc.
The phone # to Digital Age is 909-974-2859. These are the people who can send you the part you need. Also the remote that I have is RC-500, which is the newest remote control for the new Main Board. I would suggest getting this remote.
The price of the board was $123.89 with $10.00 shipping. It only took 4 days to get the board from Ontario California, and yes they do speak english.
I removed the backpanel myself and then removed the metal cover over the Main Board. Remember to mark all of your wires and screws so you can put them back in the same location. The connections are all quick disconnects and the board is one piece. I had the board replaced and the back panel back on within an hour. All buttons working on the TV and the remote control, and the TV is working great with sound.
But I do not have the Manual......does anyone have the manual? I am willing to help anyone with a fix for their TV for a copy of the TV Manual.
I hope the information I have given helps in anyway possible,
