Have a Hitachi 53sdx89BA Rear Projection TV. Turn on TV and red power light illuminates. No picture, but have sound. Check PC board in back and red led is flashing and green leds are lit. It was working...

Discharged Flyback Transformer. Removed main pc board from bottom of TV and flipped over, no apparent damaged components or blown board traces were found. Noticed a lot of flux in various areas on the board that seemed unusual (maybe TV was worked on before as I bought a showroom demo at Circuit City). Used a plastic screwdriver to remove all flux between connections on ICs, Transformers, Flyback Transformer, and various other components. Cleaned all debris, dust and crud accumulation (TV is over 10 years old and there was alot around the Flyback Transformer) from both sides of board using a lightweight paint brush.
Used a magnifying glass to check all solder joints for possible cold solders and found none. Did the same for Power Supply Board. Checked various ICs and Power Transistors for opens or shorts (in machine) and they seemed fine. Reinstalled boards, said a few Hail Mary's and fired it up.

The protector Led no longer flashed under power and lo and behold I got picture and sound!

I cleaned the lens on the projectors (again 10 years of dust accumulation) did a magic focus adjustment and it works fine!

After reading other fixes, I fully expected it to die after 10 minutes so I left it on all day and against all odds it still works.

What was the fix......Dirt buildup on and around Flyback and other components,,,,,,Flux conducting electricity between contacts on Flyback and other components.....or oxidation on connectors between Power Supply and Main Board.....I don't know.... all I know is that for the moment I saved around $ 300 - 400 in repair bills by doing it myself.

Green button comes on for 10 secs then goes off

Resolder the flyback, as thats what takes out those components if the solder is defective. Try resoldering the flyback. If the set powers up but convergence is off the FL231 has blown again due to the flybacks solder joints

I need to know where the power source is in tv

Follow the cable conenction. The TV uses a big transformer to convert the electricity, it will have a hard connection to the power cable plugging into the back of the TV. then after the power is converted it generates current to the main component board to other items, etc..

Rca big screen will not power on

There are several common failures on this model that can cause that symptom.What I usually do is first look for capacitors in the power supply that have vented(expanded and are bulged out at the top).The ones I usually find to fail are located around the heat sinks near the power cord input. Then I check the horizontal output transistor for a dead short.Which is continuety or low ohms reading between collector(middle leg) and emitter and base(two outer legs). If the horizontal output is shorted, you probably have a bad flyback transformer. This is a very common and inexpensive repair. Next I would remove board by releasing several plastic retainer clips surrounding pwr/defl pcb and test the three pico fuses located next to the flyback. Also I check the flyback transformer for cracked or cold solder joints around it's pins on bottom side of board. One of these tests should get you to the source of the problem. This is good free info. Good luck, Russmann.

Mitsubishi wt-46809 46in wont power on

You need to adjust the votages going to the crt's. As the flyback transformer starts to go out the voltages to the crts can go up and down causing the tv to shut off. It also causes red, green, or blue arced lines to show up on the screen. It can also cause some color fading in and out or flickering. Adjusting the voltages can fix the problem temporarily but in the long run it's a good idea to replace the flyback. Make sure you read up on how to do this safely.

RCA TV RCA D61W20, Light Blinks 3 Times

Usually when the crt leaks onto the chassis it can be cleaned and the affected components only have to be replaced I am not sure what "chip" you are refering too, but most ICs can be purchased as a replacement part. usually the entire board wont need replacing unless the traces are destroyed or replacement parts are unavailable.

Rear projection tv wont stay on

It is a great chance Jeff that your Power Supply Board (specially the FlyBack) could not hold the voltage requirement to let your TV set on. When local Power Utility supplier is shutdown for whenever reason, this kind of situation occurs. Voltage spikes, voltage outage, voltage drop and dimming are common things. You could replace the FlyBack and then check out if the TV stays on. This will cost you from $60.00 to $80.00, but it will not guarantee that it was the only component that suffer the shutdown. I really suggest you to replace the main power board (from $175.00 to $250.00 - with core exchange). It is something you can do on your own and I'll recommend you to check on the following site (my favorite to buy parts): SithPitt
