Transistors burning or getting hot small yellow non polorized filters in the out put area swollen(6)

Skype puts a huge drain on the battery, when the battery is under this type of load demand it gets hot. Make sure the battery doesn't look swollen, if it is remove it and put it in safe fire proof container and dispose of it as hazardous waste.

Well if you've had your ECM burn and got it changed and the same thing happen again then there might be a pilled positive wire exposed to the body or the chassis of your car touching at some point,my best advice is to trace all positive heavy wires leading from the starter and under the fuse board as well.i hope this helps thanks

it's good that you're asking as some basic sensible first aid advice can make a difference to how burns heal.

Before you treat burns you need to figure out the severity; whether they are first, second or third degree burns. This will depend on the extent of the tissue damage.

First degree burns are superficial and don't blister. The burn may be red and swollen. Run the affected area under cool water and you can put some silver sulphadiazine on it to help the healing.

Second degree burns may turn white on touch and blisters may develop. The burns extend to the middle skin layer. To treat; gently clean and dry the area. Apply antibiotic cream and seek medical treatment immediately.

Third degree burns damage all 3 skin layers and can be very dangerous and even life threatening if they affect over 90% of the body. Treatment involves immediate medical care, fluids will be needed to deal with dehydration and possibly oxygen.

If the horizontal transistor getting shorted, this could happen.
Check the transistor 2 SD1398. If found faulty replace it.
But replace black colored doides in the circuit as a whole.
Leaky diodes can not be determined easily with the multi meter.
Especialy the small high voltage diode near the small transformer
connected to the 2 SD1368 transistor.

1 swollen Capacitors / Replace
2 blown Diodes on inverter board / on some # 508 or 908
3 bad transistors in inverter bad will appear overheated powdery coat
4 replace inverter if you cannot locate problem on it
there is a safety built into the high power back light supply and that is if too much current is drawn or light is shorted it will not burn up
or hazard high volt shock to user.
capacitors and diodes driven with power transistors
look for darkened spots on the board to identify hot transistors
puffy tops and leaky bottoms of capacitors

when you turn it on does the bottom or top of the screen show image a Milli second before the other it should be evenly the lag
is the one requiring more amperage

U have a dead power supply board,burn componnents parts on the power supply board.Replaced the power supply board,u will get ur power back as normal function as before.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

switch mode power supply are very finicky check the opto coupler isolator of proper operation, also is there a non polarized capacitor at the high or hot side of the power supply, if so replace it, this can be the cause of the fault to begin with, usually around .47 mfd to 4.7, non polarized.

Good luck

First CK pico fuses around the convergence ICs big black ICs they look like resistors will be yellow or green also CK small blue capacitor behind hori out put transistor 2kv i have seen them have small burn hole on them, You may need to replace both of your STK ICs.STK394-570? Look on them they will have P/N on them. How many times does it flash before turning off? you can find out By typing in Understanding Sony Blinking Codes.

The part is a horizontal output transistor 2SD2578. There are probably other parts shorted such as a flyback transformer and or power supply components. I would not try to fix this one if I were you. Sony TV`s rarely blow just one part. Usually you have a handful of bad parts. Sony`s can be difficult even for experienced technicians.

It sounds like it is related to the red filtered glass before the prism inside the projector. When this gets to hot, it will burn a spot on the glass that causes the yellow spot. I have seen in happen on alot of epson 53c projectors. This has a red filter that is easily scratched when it gets too hot. It will actually look burnt.
