My tv just shuts off


This is a fault solution which can be checked and corrected by you assuming that there is no component failure. There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance. The best way to check for loose connections is to tap lightly when the set is powered on, if there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, and use a good soldering iron to solder all suspected points. Sometimes the fault occurs when the set warms up; if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault. It can also be related to WEAK ELECTROLYTIC capacitors as the value can reduce in time

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

Sony kp-65wv600 projection tv error code. My tv blinks 7 times.


Hi,
The Standby LED blinks when the TV is turned on, then shuts off when the picture is displayed. If the LED blinks continuously, this may indicate that the TV requires service. Before getting the TV serviced, try power resetting the TV and factory resetting. Try the below steps also: Connect the TV to a different wall outlet and check if it helps. This is to check if the issue is with the Power. Disconnect the TV from the Power Strip or the Surge Protector and connect it directly to the Wall outlet and check if it helps. To Power Reset the TV, disconnect the Power cord for a short period of time (approximately 1 minute). Then, reconnect the Power cord and power ON the TV. To factory reset the TV, turn it ON. Then while holding down the RESET button on the Remote Control, press the Power button on the TV front panel. The TV will turn OFF and then turn ON again. Then release the RESET button to complete the reset procedure. If the issue persists, service may be required.
Good Luck!!

Power went out and when it come back on the tv took a long time to start and the screen was verticle stripes (multi-color)


Check if the issue is with the TV by connecting any other device.
If the issue is with the TV, then try resetting the TV to the factory settings by performing the below steps:
To reset the TV, turn ON the TV, then while holding down the UP ARROW button on the Remote Control, press the Power button on the TV front panel.
The TV will turn OFF and then turn ON again. Then release the UP ARROW button to complete the reset procedure.

If the issue still persists, try Power resetting the TV.
To Reset the TV, please disconnect the power cord for a short period of time (approximately 1 minute). Then, reconnect the power cord and power on the TV.
If the issue still persists, service is required for the TV.

KDF70XBR950 red power light belinks 6 times repeatedly


Hi.

You have a power board error, and TV is in protect mode. This had been caused by the power surges.

Try leaving the TV disconnected from power (unplug cord) for several hours, or overnight.
This will allow PSU capacitors full discharge and can fix PSU fault after power surge. If it does not correct the problem , then there is a faulty component.
In that case the TV must be tested and repaired by a technician.

Regards.

TV TURNS OON THEN TURNS RIGHT OFF


Good Day;

More than likely your TV has "COOLANT" (ethylene glycol) on the circuit boards. This fluid comes from the CRT's (picture tube) this fluid is used to keep the CRT's cool, such the name. This fluid from the CRT's leak when TV is on for long periods of time, the chamber expands and the seals leak.

One can remove this fluid by using "acetone" & small brush. The fluid is hard to see, use bright light, they spots can be smaller then a DIME. Also, the fluid can corrode the parts and traces on the boards. To protect the TV in future place heavy plastic or thick cardboard over affective area, make sure TV has proper air flow around TV.

If after the fluid has been removed and TV still does not work, call an Authorized Service Center to come out and repair TV after giving you an Written Estimate. The boards are not available.

Always try resetting the TV by unplugging it for one minute then plug back into A/C outlet and ALWAYS UNPLUG TV BEFORE ATTEMPTING ANY REPAIR ON THE TV.
This a very common problem with model. Don't listen to other comments unless the use the correct replacement parts.

SYMPTOM: Power LED does not stop blinking after plug in.

CURE: replace C9B01, C9B02,C9B10, and C9B11 (1000 uFD 16V) on the DM PCB. Replace them with part # 181P734030 (680uFd 16V).

The DM Board (PCB) is located on the very left side of the TV looking from back. Caution on removing Board and note what cables you disconnect to access the Metal Shielded Board.


Good Luck, big IRISH.

Tv wont respond because device menu is changing through each device


I had a similar problem: my WS-55511 would not respond to the remote and the front control buttons (with the exception of Power) cycled through the Device Menu. I solved this problem by disconnecting the front panel. Here's how to do it: 0. Unplug the TV
1. Remove the speaker grill from the front by pulling forward: there are no screws. 2. Disconnect the two cables that are exposed after the grill is removed. 3. Plug the TV back in, wait for 5 minutes to reset. 4. Try using the remote.  Hope this helps!
