Wy dose the tv always make noise like some is poping inside it

popping inside electronics usually means it's power supply internally may be going bad.

Some units have "switching power supplies" and you might hear a very light click when it switches. Loud pops or frequent louder clicks are a bad sign.

My board is IBM rev. 2.8 pn 19r2563,i just clear the cmos,after that the board didn't boot anymore,no power at all,,please somebody help what exactly the problem is..

Look on the board for bloated or leaking capacitors- these are caps that have an x on the top and a yellow or brown substance out of them. If the are fat they are bloated. Next, I have had this with bad power supplies. Try another power supply or put that one on a power supply tester if you have one. It will tell you if all the voltages are there. It only takes one voltage missing to give you major headaches. If the unit is old try measuring the CMOS battery. A dead one will not let the computer boot but that is after power will come on.
If you have a bad capacitor on the board it will be needing replacement- I fix them but not everybody goes to that trouble.

Cost of replacing body electronic control unit

The body ECU usually costs about $700, depending on year and model but it's an average price from the dealer. There are other things that may cause the defroster to not turn on including an open fuse, a bad switch or an opern citcuit in the wiring.

No sound but have power

Not sure which model you have as there are at least 13 cobra 29's. I am using the LTD as an example. Do you have a good good mic and cable? Is it made for this model? If it is good then I would have to say the final audio stage is not working. The TA72222AP is the IC that is the final audio amplifier. Check pin 1 of the TA72222AP ic for 12 volts. If 12 volts is present then replace the audio IC TA72222AP. If 12 volts is not present then you have power supply problems that are internal. Is there meter movement during modulation check? If so then your audio is fine and I would check the spkr jacks and speaker. Plug in another speaker in the speaker jack and see if it works now. If so then of course your speaker is bad. If that all fails then I'm 99.99% sure its the final audio stage is a bad. If your model is not the LTD then the IC could be different but still the same audio final is bad. Replace the part which should be fairly inexpensive. If it uses a metal heat sink be sure to apply heat sink grease when installing new part.

Philips Projection 60PP90200D/37 NO PIC NO SND 6X/1QF

I had the same problem. It is error code 61 which is a power supply fault. Had a bad LSB board (pn: 313926719011 from MCM Electronics) which blew out on of my CRT. If you have any observed arcing in your CRT's, they are bad and will need to be replaced. I went to Ebay and found a used compatible Philips brand to replaced the CRT. Do not isolate the high voltage lines of the bad CRT to troubleshoot with a bad LSB. The LSB will short out another CRT (it did on mine). I bought the service manual an learned the set does not tolerant of power line surges. If you fix it, invest is a good surge protector.
