What is the problem of television philips model that have no power or dead set.thank you for your response

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Hi Rito,
No power means the power supply board in your set is not working at all or the ac power is not reaching there. so the power supply board has to be checked and repaired or replaced.

If set is dead, no power begin by looking for and at the main fuse it has.

i have the same problem anyone know what that problem might be?

Check the power source?Yes,than the power supply board is dead.Tries websites like Dhopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Ur power supply board is dead.Must replaced the power supply board to solved this.Tries Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

An issue i came across with this particular model tv was there were two (2) 3300 micro-farad 25v caps on the power board that have gone bad, preventing the tv from starting up. I replace those two capacitors and it started right up! I suggest having a tech do it, unless u have experience with electronics. I cannot be held responsible for any damage done to your tv, warranties voided, or shocks you may receive. but that should get it to start back up.

There is a install kit 483531057673 for this model when the set is dead. The kit will contain 7404 and the Horizontal Driver Transformer 5402 along with resistors that will limit stress on 7404 and includes complete instructions.

Check the site www.TvRepairKits.com. They have put together a couple of kits to fix the chirping set/dead set condition. If you don't see your model listed send them and email and they will build a parts kit for you.
