Downtown off sixth street. Just kidding. This set has an a/c power supply located outside the wooden frame that secures the main and deflection circuit boards. Very seldom does this cause a problem though. The most common problem in my experience is convergence failure. Testing this is easy. The convergence board is seperate and is mounted above the others. Small pcb with large heatsink. Removing the blue wires with the red plug(I think it's a 5 pin plug) should restore power if set is in shutdown due to that failure. Then you can just try to replace that board if avail. Next problem on this set is coolant can start leaking from the tubes and go onto the circuit boards. Use a bright light and a good pair of eyes to examine the board closely, looking beneath the picture tubes for moisture or drops or corrosion on boards. Please make sure tv is disconnected from power source while testing and good luck, Russmann.

I just inherited a PT4298HD Akai television I plugged in and all i get is the red light blinking. I was wondering if it is worth repairing. If it is can you give me diagrams of what to look at?
