I have a Sony kp48v80 that needs a new A PCM board. However, Sony has stopped making the part and I can't seem to find it anywhere. The part number is "a1299051a" but no one on the internet seems to have it. I hate to discard a great tv for lack of a $300 dollar part. The part that is bad is the HV transformer and Sony has stopped making that too.

Your model uses two of the STK392-150 ICs however there are also pico fuses and convergence resistors that will normally require replacement along with the ICs. You can get The Sony repair kit called " KP48V80 - KP61V80 Convergence repair Kit " which works for the KP53S76 models too and it has the Two Ics with heat sink , the pico fuses and the 12 resistors. The kit is listed on the following page http://tvrepairworld.com/sony_repair_kits
Have you tried swapping the PCM? It may have busted capacitor that's why the maf is not working properly. Please do check the PCM for burn, you may need a PCM replacement just incase it's faulty. Please keep me posted on the progress.
Check for grease on the platter or anywhere in the mechanism. Sometimes somebody has messed around with the speed preset, there might be two. You could try adjusting them. Sometimes they are found on the underside of the turntable, covered up, or they will be on the PC board of the deck.
You need to make sure that power supply has fried. It requires to check output voltage by volt meter. What is the exact model number of your Sony home theater system to guide you properly. Is it DAV-S500 or some thing else.
you will need to replace the stk ic's they are mounted to 2 large heat sinks in side the tv. the ic numbers are on the chips themselves. i do believe it is stk392-510 for sony. once you have the number you can buy these anywhere online. just put new ones in and should be good to go. if this doesnt work then there are a few resistors and fuses by the ic's that sometimes fail.
