AKAI PDP4249G Losing Picture and Sound

My tv recently started acting up. I will be watching tv just fine, and all of a sudden the picture and sound goes out, and the speakers make a strange crackling type noise. The tv then proceeds to Auto search for signal, but in never does find any signal. In order for the tv to work again, I have to leave the tv turned off for a few hours before it works again, but then it just repeats the cycle of losing picture and sound again after about 10 minutes or so of viewing (sometimes it may take longer than 10 minutes, but it will eventually reproduce the problem).

Anyone have any ideas???

    I would also like to add, that sometimes when I press Brightness, Freeze, and Menu in rapid succession, the picture comes back, but there is still no sound.

Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main 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. 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.

This is a pitcure tube problem, either you buy another picture tube and change it on your TV or if this is under warranty better to send it back to the manufacturer and have this one repair.

With no picture but only sound on my Akai PDP 4294


Try replacing the Y-sustain board. Might have to replace buffers attached to it too. Have you had it diagnosed? My picture went out and I replaced the power supply board. Worked for 2 weeks then acted up again. Got a different power supply board. Same thing 2 weeks later. Was told it now was a bad Y-sustain board. Replaced y-sustain board. Worked OK for about 2 hours then started having picture issues. Not the same issues before power supply or y-sustain problem. Was told that you might have to replace buffers attached to y-sustain when you replace y-sustain. Tired of dealing with it and only watch a couple hours a day, so I don't always have the problem unless I watch the TV for a long time. Will eventually replace buffers to see if that works. I would definitely find a place that gives free estimates or close to free to get a technician diagnosis. Then you can decide if you are able to do the work yourself.

No picture ; no sound


the red blinking light usually has a pattern that gives you a code to the possible problem.
Maybe you have a bad power supply board. You have to open the panel and do a few tests on the power supply's outputs to be sure.
It produces a variety of voltages for different parts of the tv ie. the plasma display panel and the audio system. The components supplying power to the audio system may have failed a year ago and recently the pdp.

plasma tv's are expensive to repair, most of the time you can get a better tv for the same price. You can reduce that cost by learning and troubleshooting it yourself.
