SOURCE: Philips 42PF5321D/37 Error Codes
replacing ssb for 4 blink error was correct as error is communication failure specific to micro processor on ssb. getting an alternate error after replacing ssb would suggest either wrong ssb or defective ssb. verify vendor number on ssb tuner on original and new ssb and if same reorder that board and if not order per original board

Normally, this happens when the TV detects a bad circuit board and goes into " Protection Mode ". The blinking red light should be a error trouble code. I don't have the Service Manual on hand for your model number to tell you what the code means.
Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.
You have a few choices:
1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.
3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.
4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
I hope I shed some light on the subject for you.

Yes I had the same problem. Replace the two 33000microF caps. I would be careful replacing them with a higher rating (12 or 16 volts) just replace them with the same rating and should work fine. If not go to ebay and there are several power supply boards that you can buy cheap. That would help you if you don't have any component level electronics training or experience.

I work on Daytek 4660 models. I have seen the problem you are having and have solved it a couple of times by replacing all the capacitors in the power supply. If you use an oscilloscope to measure the voltages they may appear fine, however I have solved this problem by replacing all the capacitors in the 2ndary circuit of the power supply. It doesn't always work, but has worked in about half of the TVs that have come in with this problem. Also, just to make sure, if you remove the shielding from the board that drives the LCD panel make sure the little smt fuse is good. It's right on the 5V power line close to the ribbon connector from the main board.

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
