SOURCE: TV does not turn on/red led flashes 7 times in front

this is common issue with this model and through your troubleshooting is tied to y main board. blinking led on logic main in normal operation. when replacing y main always good idea to replace y upper and lowe buffer boards as they complete a circuit and sometimes replacing one without other could cause additional failure on remaining boards

Measure the connector from the logic board to the power supply the second pin from the left it will say Vs_ On if the set has 3.1 volts the problem is the SSB or the logic board. On the logic board there should be a solid led and a flashing led that shown that data id flowing and the problem is the SSB. The SSB is easy to replace just remember what you tokk loose and from where. You probely will save money that way. If the set is in warranty or just out of warranty contact Philips 1-888-744-5477 and see what they can do first.

SOURCE: Panasonic plasma 50PZ85 power led blink 10 times

Either a bad power supply or a bad processor board.
A Good Service Shop should know what the 10 blinks are indicating.
May be a repair cost between $200 and 400 dollars.
Be prepared -

5 times The print head is not installed properly. - Install the print head, and close the

8 times Warning: The waste ink absorber is almost full (approx. 95% of the

maximum capacity). Pressing the Resume/Cancel buttonwill exit the error, and enable printing.

In repair servicing, replace the bottom case unit (QM2-0647), or 5-item set of

the ink absorbers

Philips 42pf7320a/37 dead


Error 7 is a power related problem. This is what u need to do.
Remove back cover.
Plug in power when tv goes into error protection, check power supply and see how many times the led flashes. Right below the flashing green led there is a list 1-13 of error codes and what they mean. Your problem will probably be an error 7or 8 VSET or VSCAN . Which ever error code it gives you VA VSET or VSCAN or whatever it indicates look at the cable connectors to the power supply unplug that connector and the TV will stay on. And there will be your problem.

New logic board installed cant install driver


After installing a new i9900 logic board, you *must* configure the destination country setting. The default setting is probably for Japan (PIXUS 9900i):

1. With the printer powered off, hold down the resume button and press the power button.

2. While holding down the power button, release the resume button and press the resume button two times. Now release the power button. The LED will blink green and remain lit in green. You are now in Service Mode.

3. Press the resume button 5 times to get to Model Setting mode. The LED will turn orange. Then press the resume button two times to set the model number to i9900 (LTR). Press the power button once to lock in this setting and turn off the printer.

Kv24fs120 dead set with two led blinks


Two-blinks of the "Diagnostic STANDBY/TIMER LED" indicates one of two things:

1) Horizontal Output (Q502) in shorted on the A-board.

or

2) IC702 is shorted (CB board)

Two-blinks of the diagnostic red LED is a " B+ Overcurrent" problem.
The red LED will blink 2-times, stay off for 3 seconds, then blink 2-times. The cycle repeats.

The circuit board is quite delicate. One should not attempt repairs (unless one has high quality vacuum desoldering equipment such as a PACE desoldering unit).
