    What was INAPPROPRIATE about my answer. You were looking for the part number, correct? I was guessing you wanted the Canon OEM part number..... I have ordered one years ago and it could not be ordered from a Canon Dealer...... If you could not read the part number on the part it's self, I would say to go to a eye doctor to get you eyes checked.. Or clean the "F______" sand form your eye's. And what is "IGHT" mean, is that some kind of Camel Joggy Lingo????? Why, don't you get a newer copier and stop wasting time on a copier that is over 10 years old. Oh, thats right you live in a THIRD WORLD COUNTRY.......*******

How do I fix backlight problem on JVC LT32D-500 TV. I want to know if it is perhaps a common problem with this model and it it is FET or transistor related.


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

On and then automatic off in seconds


check for a shorted component parts at the power supply board like the bridge diode and fet transistor.look also for any burnt parts in PSU and in the main board.

My RCA T19060GY TV/VCR will not stay on. When I push the power button on the unit itself (I don't have the remote.), the green indicator light comes on for two seconds and I hear to click sounds


the clicking sound is due to the relay is getting turn on but doesn't stay because of bad component in the power supply board or in the main board. you must check first the bridge type diode and FET transistor using an analog or digital tester.

Sat went out lost power. can not get tv to turn on. checked outlet (fine) sat powered up. no tv power.


When this happened it probably took out Q406 a switching field effect transistor on the power supply board along with F401 an 8 amp Slow Blow fuse. The FET will have to be soldered in if it is bad. If the fuse is blackened, it is almost certain that the FET is shorted as well.

Please tell me about power supply problem and solving diegrame


The power supply for HDTV is the board where the AC plug goes into. It is a very sensitive circuitry that can be easily damaged. Under normal circumstance it is very reliable. This is how they work basically. The AC current is rectified (converted into DC). Then filtered by means of large capacitors. The DC Voltage ( about 180 DC volts from 120 AC) is supplied to power transistors (usually FET or field effect transistor). The Transistor are switched at high frequency( usually over 100KHZ or 100,000 times per second) Which drives the transformers to step down the voltage. When the TV is off there is a standby voltage which is on at all times, and it is typically 5V. This standby voltage is the first thing a technician check for when troubleshooting power supply problem. When the TV is turned on everything in the power supply comes to life supplying power to every circuit boards which are of diffrent voltages such 12V, 24V etc. HDTV power supplies are very complicated using the latest technology employing power saving chips that minimize power usage on standby mode. Explaining the it in great detail would require many pages but this is just the basic.

Pmp3000 problem power supply.ic circuit problem.number series ic circiut..


I have a PMP5000 that I had to resurect. I had to trace out the power supply to repair it.

I can give you hint: First, a small supply runs directely from the line and generates some of the small voltages. While this starts, the main power caps are charged through limiting resistors. The main switcher is brought online and if the power amps acheive balance, then a relay connects the speakers and shorts the limiting resistors.

This is what is in the 5000 and I suspect the 3000 is similar.

In my 5000, there was arcing at one side of the power amps. The board was burned and three power fets fried. Cancer of burned board had to be carved out and traces replaced by hardwiring.
In addition, the limiting resistors were blown open, both main switching transistors were blown and 4 small driver transistors (surface mounted) and several diodes AND a switching regulator chip (surface mounted).all fried/

Hint: When restarting the unit, put a 150 watt light in series with one of side of the power input to limit the current in case you did not get all the dead bodies out.

This is a class "D" amp which drives PCM waves into a filter which is then the audio output. It is much more efficient thaan a linear amp.

27GT722 Blows Fuse


There should be a part designation written on the board under that part. FOr example Qxxx or Dxxx. Can you post that here please? I can cross reference that designation using the model number to get you the part number, cost and description.

I'm not familiar with that particular amp but generally, the only transistors that burn are the ones in the power supply. If the adjacent transistors had numbers like IRFZ44, IRF3205 or similar, the burned transistor is likely the same as the ones next to it.

Confirm that the center and right-most leg of the burned transistor and the transistor next to it are directly connected by large traces on the circuit board. Also confirm that the center leg goes to the large windings of the power transformer. If it passes these tests, the transistor is one of the power supply FETs. The numbers on the adjacent (parallel connected) parts will be the same as the burned one.
