Philips 42PF7220A/37 April 2006. Chassis Number BP2.3U

I have a Philips 42PF7220A/37 April 2006. Chassis Number BP2.3U TV that does not work. The front LED flashes red seven times and the power supply led flashes green three times. VSCAN voltage drops to zero (or climbs). I unplugged the power feed cable to the y-sustain board and the error codes go away and VSCAN voltage remains at -190VDC. I replaced the y-sustain board and the error codes went away for approximately 30 minutes only to return again. I still did not have a picture for that 30 minutes

    O.K. I was able to solve this problem on my own. I had to replace both Y-Buffer cards (Upper and Lower) along with the Y-Sustain card.



    I purchased the cards from the http://www.vancebaldwin.com/ website.



    I took a long time for the cards to arrive. Even with the long wait, I am pleased with the results.

    Same problem with the same model here. How much are these cards and what model numbers? I went to the site and couldn't find them.

    I tried to format the table as good but I goofed.



    I googled the OEM part number and found the cards.



    I could not find the site where I found the table. It took a lot of searching.

    I googled the part numbers and ended up on a website that allowed me to purchase the buffer cards for around $120.00 each. The Y sustain card was purchased of of e-bay for $80.00 including shipping. I think that I got lucky with the Y sustain card.

    It took a lot of searching to find the cards.

    Each card had multiple part numbers on them.

    LJ41-02759A = LJ92-01200A = Y Sustain
    LJ41-02760A = LJ92-01202A = Y Buffer Upper
    LJ41-02761A = LJ92-01203A = Y Buffer Lower

    I searched today for the same part numbers and they were priced much higher.

    The site was a Vance Baldwin parts store which is where philips must be distributing their replacement parts.

Most likely the YSCAN UPPER board and/or YSCAN LOWER Board also gone. Your new YSUS board may damage again if you don't replace the bad YSCAN boards. Try to replace the three boards together and then to verify which boards are bad one by one. Good luck.

I think its something on the picture frame board or on the line output board. I would sway to the line output simply because I think but not sure that error code is linked to the line output stage plus when you unplugged the cable the voltage seems within parameters. Good luck.

I want to screen share on my philips smart tv using my samsung tablet, but when i go to pair them my tablet wants an 8 didgit code that the tv manual says should be on the left side of the tv screen?


did you put the tv into pairing mode so the tablet can discover it . I suspect once the tv is put into pairing mode it will reveal the pairing code needed.

Philips flat screen TV, model 47PFL5432D/37 46" Problem one: Have to turn on and off several times to get it to come on. Problem two: screen darker on one side and screen flutters/flashes.


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I have a 37" Olivia that one of the speakers emits a very harsh static. The speakers are actually turned off but this noise comes through the tv speakers anyway. I want to disconnect the tv speakers


Check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Pull up older posts.

I have a Sony kds-60A2020 with no sound or picture but what I get at firs on power on is 2 green blinks and then 7 red blinks


Those 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.
http://electronicshelponline.blogspot.com/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
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.

Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. In some cases, the remote control might need to clean.
