Phillips 30" Mod 30pw633r37a

This sounds like a lazy lamp--that is getting hard to start. Try a new lamp first. If you are inclined to do so--get a bard bulb and install in the old lamp housing and save some money. Get a real PHILLIPS bulb--it will last a while--compared to cheap generics that are good for maybe 6 months !!

the model is phillips and picture above is Hitachi--the philips is not customer repairable--call around and get a estimate.

Are you getting some kind of high pitched squeel from set when you try to turn it on?

The more you tell me the more I can help.

Look for a button on your Philips remote labeled Format. This button will cycle through the picture formats available for that signal. Press it until you find one you like.

Hope that helps!

It sounds like a defective capacitor in the deflection circuit. Check all of the high voltage caps.

I have a philips magnavox and had two problems that I recently fixed using kits from www.TvRepairKits.com. I can't say enough about their kits and help. Without them I would have never been able to fix my TV set myself.

The first problem I had was the TV was looking 3D. After doing some homework I found out that this is a convergence problem. I bought a kit, followed the instructions, and to my amazement fixed it myself.

After building my confidence with the 1st repair I decided to get their CRT fluid kit. This kit fixes the dull video,red video, or bright/halo looking video. If you have a magmavox set that is more than 5 years old your tv has this problem already. It happens on every set. As before I bought the kit, followed the instructions, and now my video looks factory new. Once again I wanted to say thanks to the team at Tv Repair Kits for putting together kits that the average joe can use.

The main power supply regulator section circuit fault. 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.

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.

Replace the crt socket.

Probably a defective power supply

Hi Panix:
Sorry, but it sounds as if the power supply or high voltage circuit has failed. You will have to take it to a repair shop.
