SOURCE: Philips 42PF7320A/37 won't power up Led blinks 7 times

This what to do measure from the logic board which is located under the small signal board and have the AV jacks connected to it. If the voltage is 3.1 or close the problem is with the power supply or a boar connected to the power supply. Unplug the set. Disconnect the Y main board first that will be on the left side of the set facing the back. Plug the set back in if the led is solid replace the Y main and the Y upper lower. If still blinking plug the Y main back in and unplug the X main which is on the right side facing the back. If the led is green replace the X main. If the led is still blinking replace the power supply.
But if the volts are 0 the problem is the SSB or the logic board. In that case take the (SSB) small signal board out the set and place 1 jumper on J8003 and another jumper J8004 of the left side of the power supply. Then place 1 jumper on CN2072 of the lower left part of the logic board. Plug the set back in if the set displays a white, blue ect screen replace the SSB. If not and on the logic board you don't have 1 solid blue led and 1 blinking led data is not flowing and change the logic board.

7 blinks indicates a bad buffer board, usually I replaced the Y board and the buffer/s about $500-600 in parts. but before you buy anything open the set and look at the power supply if you see two capacitors that look swollen , bulging on top they need to be changed and may solve the issue. the power supply is middle top . If you are not wanting to repair it yourself then know that you do have some circuit board repairs needed.

This fix was posted on similar problem, worthy of repeating: Replaced 3300mf 10V capacitors at PS. Both had bulged slightly. Upsized to 25V as the previous solution poster had suggested 16V but I could not locate 16V so used 25V and TV is back to normal!

Five buck solution; If you have any tek skills at all and are feeling adventurous; UNPLUG THE POWER, remove the back panel; You will be faced with the mainboard. In the lower right quadrant you will see two small capacitors, like tiny yellowish coke cans. If these are bulging, there lies your problem. These must be replaced. If you have no soldering skills, take only the mainboard to a fixit shop and have them solder in the two capacitors easily found on line. No guarantee's but worth a try

Engineers are right, you need a new LED panel., or the component that supplies the light to the screen.

What may cause screen to turn green and then black out.? power LED is blinking three times then pause and repeat. unplugging tv did not resolve problem. single click can be heard from center of tv wh


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. Viewing it in "Mosaic" or "Magazine" will make surf easy.

Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location.

Are there any blown caps on the PSB-power supply board. Most sets have sammy boards and they used very shotty caps. If there are no visual clues being a poped cap at the top (X) they simply often do vaporize and dry out. The YSUS-Main and the 2 Y buffer boards control the picture OSD-on screen display. Your not getting any of that. So power supply is where you start first. The YBU-upper and the YBL-lower control the upper and lower OSD the Ysus main control both of them. Usually if you have one in the door you have to replace all 3. But not always. If you were to replace any of the boards I would replace the YSUS-Main, or get the board reworked at a pc repair shop that does board level test and repai. Its more cost effective.

Best Regards and Semper Fi
