Philips technicians will not be able to service it as they are "Card" technicians. You will require a "Component Level" technician for resolving your issue. If you are lucky some of the old generation "uncles" used to do "component level" repairs. Most components should be available in the market as they mostly use standard components in TV. The challenge will be to isolate the issue completely and repair the TV. For this the service technician need to be proficient in his theory. Suggest you to try and get a service manual for your model from the internet. That should be the first step to get the issue fixed. Also look for a TV technician in the mean while.
"Card" technician !!! Well said Mr. Iyer.
Very interesting anecdote relating to 'card technicians'
I am from Kolkata, I use local train for daily commuting. Just last year, I got the opportunity to hear a conversation between two technicians in a jam-packed compartment. One of them was looking for a technician job in a company that takes care of service requirement of LCD/LEDs of two major electronic companies. The guy, who's looking for a job was not confident, but the other guy ( who seemed experienced) told him, " You need not worry, just locate the section where the fault lies, remove the card of that section, replace it, your job is done; even if it is a small capacitor, you don't have to change it, just bring the 'faulty' card, our in-house tech will change the component, and it will be used again, though customer(end-user) has to pay the total cost of the card"
Story doesn't end here, that guy went further and said, " If everything goes above your head, tell the customer that PANEL HAS GONE BAD"
He also added, "At times, we get calls for silly issues and factory reset is the way to resolve those silly issues, but you don't do it immediately, look very serious, pretend as if you are very busy solving some serious problem, take good amount of time, more so if you have completed your day's target, tell hapless customer that you need a glass of water or flashlight or something or the other just to make customer busy, so that he doesn't get the chance to see what you are doing actually, if customer doesn't move away, change few resistors or caps. After spending more than half an hour, do factory reset and EUREKA! TV is running well again; now charge a hefty amount, remember! this way you earn your salary, if you are a 'Good Performer' you will come under direct pay-roll of the company, your future will be bright". :clapping: :clapping: :clapping:
