It could possibly be something wrong with the computer inside the tv. And you can either pay to get it repaired or buy a new one unfortunately. I would try to contact the makers of the tv though first and make sure to have the model number and all of that ready.
There is a burnt capacitor somewhere in the unit. Look for any burnt or swelled up capacitors. You can also usually locate a bad cap if there is burn marks on the system board. Also test power supply with voltmmeter to make sure it is a constant volt reading.
there is a weakness in the power, this could be power board or the main av board. the capacitors would be the main problem as they control the voltage around the power board and also on the av board. you maybe able to see the problem if the capacitors caps have rounded at the top, but on the av board this is harder to notice as they dont go rounded at the top they need checking with a meter to see if the voltage is right coming out onto the board. these are called smd capacitors and are soldered to the top of the board and a lot smaller than normal capacitors. a visual look at the power board would be needed to see if there is a problem
Yes, I'm sure the board is bad. I had the TV checked out by a local TV repair shop. I also opened the thing up to see if I could do anything with it and it's obvious that this is the board that has bitten the dust. The correct number for the board is AA98-00188A. I made a typo in the first post.
I also have the akai PDP4273M1 tv with power and no picture and I looked at the power supply board inside and found 1 of the FMG26S chips blown and I am looking into replacing this to see if that does it and if not do a search for SANKEN PSC10165B M and for approx 170.00 you can get a whole new power supply for it and its easy to put in..
The Power Supply Board is listed below. Please note, there are 2 models with the same beginning number (PDP4294). Verify your model number before selecting the Power Supply Board as each board is different depending on the model number.
kindly specify the complete brand model of the tv..
thank you
