Good day; TRY THESE SOLUTIONS: 1. CHECK IC7A00 PIN 53 FOR LOW LOGIC (0 VOLTS), IF HIGH (3.3 VDC) CHECK FOR SHORTED D9A31 PART # 264P045050 AND OPEN R9A33 220 OHM 1/4 WATT ON THE POWER PCB. This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. SELF- DIAGNOSIS INDICATE X-RAY. CHECK FOR A SHORTED IC5A03 PART # 270P704010 AND AN OPEN R5A73 82K ¼ WATT OFF PIN 2 OF IC5A02 ON THE MAIN PCB. 2. SELF DIAGNOSIS ERROR INDICATES SHORT PROTECT. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. 3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB. I hope this more helpful, big IRISH.

I had the same problem. blinking 9 times, pausing, 9 times...... remote would not power the tv on. after five minutes of pressing the remote it finally would. after turning it off you would have the same problem. sometimes a half hour of pressing remote in every which what way. finally left the tv on for three days and would mute at nite to go to bed. didn't think that was the best way so turned it off and it never turned back on. checked all the forums and found out it was the g board. unfortunately, you cant buy the whole g board anymore. if you take the back panel off the tv, on the lower left corner is where the g-board is. there are 3 little things to unplug and two screws (phillips head) in the middle of the g board. its simple to figure how to take it out. go to the sony direct parts website. the part # is A1054157A for the g board. since they dont sell it anymore they have a phase 3 program where you send in your old g board and they repair it for 64.95. it'll cost about 8 bucks to ship it to them. better than the 400 bucks the tv guy wanted. address is sony customer satisfaction ctr. , materials door 27H, mount pleasant, PA 15666 there number is 866-748-8272. call first and they give you the step by step instructions what to do. after tax and shipping it came out to less than 80 dollars.even came with a warranty. got it back in a week, popped it in and just love turning the tv on. anyone can do it.

It might be the relay itself, you sound tech savy have you tried testing the transformer and various other main board componets?

Toshiba television wont power up


First would be if total dead--open and look for a bad fuse.

general information:

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

I have a Sony rear projection tv KP-57HW40 won't


Follow the power cord (set unplugged) into the set as it goes directly to the main fuse (should be 6.3 amp) and see if it is good or bad.

I purchased a JVC LT52X579 March 30/09. The TV would phase out by itself and then restart by itself. Some times it would remain on and could be cut off only by unplugging it from my sudge protection...


Hi,
Please unplug TV from wall socket for couple of minutes, replug back in and turn ON.
If still does not power up, try it in another wall socket.
Also check standby/ power light flashing or its solid at TV.
If standby light is flashing or its not lit then TV got power supply problem and requires qualified TV tech. I hope TV is still under warranty so ask for warranty cover to store.
Thanks.

NO POWER AT POWER SUPPLY BOARD EVEN AFTER REPLACING FUSE.


If the mains cord has only 2 pin plug, you can plug it the other way to see if the mains cord has an open circuit at one of the wires. It is not uncommon to find open circuited mains cord for a large appliance like a TV. The degaussing circuit causes a surge in current consumption when you switch on the TV from cold.

Your fuse will be on the main board just after the power cord inlet. Maybe in a small black box that the top opens on.

Hello,
It sounds as though you have a damaged the main board ( power supply board). First I would suggest you check the fuses, in both the main board and also the convergence board ( there are two main boards in your set ). Before you start, always use caution by unplugging the set from the wall. To check the fuses, remove the bottom panel cover in the back of the set by removing the screws. Use a flashlight and observe all the fuses you can find and see if any are opened or burned out. ( if the fuse is burned out, it will be black, you may not be able to see if the fuse is just opened without using a continuity checker ( volt ohm meter ) ). Any fuses you find open or burned out, replace with a like fuse ( voltage and amperage ). The set should work fine if a fuse is the problem. If the set doesn't have a bad fuse or won't work after replacing a bad fuse, then you will probably have to seek professional help. Check www.sony.com for service in your area. Good luck. I hope this has helped.
