that input is called DVI digital video interface it is only for video. there should be some red and white composite input jacks for the audio near the DVI connector. you will need to hookup the red and white cables from the tv to the cable box or dvd player or whatver you are using. good luck

If you browse www.philips.com for a manual, that will help you in the future as well as now.

This is a very common problem. Your Flyback/HVG has gone out. The most commion symptom is that you have audio but no video. We see this all the time on the DPTV3XX models. The bad news is that its nearly impossible to find one.

Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Solution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

Solution #2


What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc

TWO THINGS:
1. GO into customer menu and select convergence--you should bring up a grid of lines--see if red is skewed or the yellow lines are outlined with red edges.

2. Look at the attached photos and tell me if they look ANYTHING like your problem.

If this information or the photos helped you, rate this solution as very helpful as I do this here for free.

remember, no two sets will look exactly the same but you will know if this is your problem. If it is I can tell you how to fix it for under 30 dollars total parts cost.

need replace convergence ic chips to resolve this issue, parts cost about $40

I had a similar problem with my 42 in Philips LCD HDTV.

Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.

Here are some options for you.

1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found at tv-part.com but supplies are limited. I would definitely shop around though.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.

Hope this helps and if it does please rate it accordingly. Good luck.

it is the convergence board you may be able to have a tech come out and go into the service menu and fix it that way. (otherwise you will need the new part)

had a very similar situation with my Phillips 42 in. LCD TV.

Here was my Problem. The Power Supply Board. I opened it up( Warranty was Expired) and found several faulty capacitors on the PSB. Its pretty common. Major Electronic companies were sold faulty capacitors that fail in 2-5 years instead of 10-20 due to a lack of preservatives. It wouldn't surprise me if you have the same problem. TV will work fine for a few years and then just fail completely or slowly deteriorate.

Here are the solutions
1. Have it Repaired
2. Check for faulty caps and if you find some(budged or leaking) you know you have located a problem
Remove the board and replace the whole thing.
3. If you have some soldering skills you can replace the faulty caps.
Caps are very inexpensive, under a dollar in most cases. I replaced 4 for about $5.00

Hope this Helps.
Good Luck

Replace the two convergence ICs and the 6.8 ohm resistors. The DPTV305 - DPTV345 convergence repair kit from www.tvrepairworld.com works for your model and contains the cd with instructions

Convergence ICs they are big black ICs will have PN# on them STK392-???

CRT coolant needs replacement. The red has become dominate due to the green coolant needing replacement. The blue will soon follow and red will be the only color that wont get affected. You can get the phillips CRT coolant kit from www.tvrepairworld.com the kit contains the coolant and the CD with instructions.

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

You will need to start from the begining, check from thepower supply and move on to the micro controller section.
Use a good multimeter to check and see the voltage to all the sections only to find the missing section to identify the fault.
Look for damaged components, possible capacitors, fusible resistors or can be bad soldering joints in the power sections.
Use a good irron to touch up the suspected areas and check out power sections producing heat.
Hope you get the action going.

The Philips and Magnavox sets have a way of the anti freeze going cloudy in the green and blue guns. Look (with a pair of sunglasses, while the set is running)) into the lenses, and make sure there is no haziness in the coupling lens (the lens the liquid makes up). This anti freeze keeps the CRT cool since they are run fairly hard, and generate lots of heat.

I have done 2 Philips sets just this week for anti freeze trouble. It should be clear as water, if it is not, that is the trouble. Your trouble could be that the anti freeze levels have dropped, the top of the coupling lens chamber, when the projected image hits the front of the set, appears at bottom of the screen. The image will be out of focus in the area where the anti freeze is gone.
