Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electro-medical.blogspot.com/ http://homenol.blogspot.com/ http://electronicshelponline.blogspot.com/ If blinks continue without any pause, the main board is faulty.

i would check the power fuse If you need further help, reach me via phone at https://www.6ya.com/expert/david_eb7ea98642566cc6

You hear about fiber optic cables whenever people talk about the telephone system, the cable TV system or the Internet. Fiber-optic lines are strands of optically pure glass as thin as a human hair that carry digital information over long distances. They are also used in medical imaging and mechanical engineering inspection. In this article, we will show you how these tiny strands of glass transmit light and the fascinating way that these strands are made. Fiber Optic Patch Cables

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem. Below are two of the most common problems encountered with projection TV sets. Problem #1 - CONVERGENCE PROBLEMProjection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. This is a very common failure on Projection TV sets and a fairly simple DIY fix.Common Symptoms include....

• 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.
• TV shuts off after powering on - TV may also make a chirping noise.

Here are some photos of convergence problems.Here is a quick test....Using your original remote go-to the settings menu then goto the convergence section.Try to adjust the red and then the blue convergence.You should be able to move RED and BLUE in all directions - up, down, left, and right.If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem. Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solutionCONVERGENCE SOLUTIONYou will need to replace the convergence chips and possibly some convergence resistors and pico fuses. This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from TvRepairKits.comTheir kits include a step by step instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc. Problem #2 CRT Fluid is CloudyProjection 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 video. Pic of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc. BEFORESet after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again. AFTERSolution #2 - CRT FLUID FIX

Remove all batteries from your remotes. Unplug the unit for several minutes. Plug unit in and use the controls on the set to turn it on and adjust the volume. This will eliminate the remotes. They could have a button stuck. If this does not work you may have a legitimate problem and need a tech.

The set will need a digital box to receive digital channels as it does not have a digital tuner in it--it is a very good set.

This set with front grill removed has a tiny blue button on front edge of chassis on left side that will manually take set to convergence mode but you must have the Hitachi working remote to do adjustments---different buttons on the remote adjust and save the adjustments, I have the Hitachi book that shows all remotes they use and which buttons do what---if convergence is real bad most likely the two chips for convergence need to be replaced if Magic focus will not help.

Check this link for more details.

The camera output would have to be composite---and if so go to one of the rear audio/video inputs: yellow (composite video) is likely all you would need unless the camera has audio as well (go to red or white on same input).

I have the same problem. I took the back cover off of the TV and blew all of the dust out and the TV started working again. But this only lasted 2 days. Now the TV is dark again.

PICTURE IN PICTURE IS ON

yes its at www.tvrepairworld.com and is listed under the Hitachi repair kits category as the DP14G convergence repair kit.

thats the convergence ICs and associated resistors your model is the DP14G chassis and the Hitachi DP14G convergence kit is available from www.tvrepairworld.com and includes the two ICs associated resistors and the cd with repair instructions.

Hi,

First, make sure that the mute is not on. If not, internal speakers must be check using the multimeter. Check its continuity, it should be 8 ohms and you will hear a crackling sound upon testing. Open voice coil of the speakers will not produce any sound output.

If you've confirmed that the speakers are not the issue, then it is caused by faultly sound output IC (IC01/TA8200). 29V must be check if present at pin 9. If yes, replaced IC01.
If you can't troubleshoot the unit yourself, I would advice you to ask for an assistance of a qualified TV technician.


Hope I helped you.
Have a nice day!
Thanks for using Fixya.

The tv have a problems known as a convergence picture problems,it is dead.Tv set have any colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?Yes,than the tv convergence board it is dead to causes all these problems.Now the tv set convergence board must have to be repair like replacing 2 STK convergence ICS and some or all of it resistors too.To fixed the tv set convergence board to solved the tv set convergence pictures promblems.The tvs shops will cost u like $300-350 for parts and labors.

You need to replace the Convergence ICs, they also control Startup. They are big Black ICs and will have the Part number on them STK392-110 use 120s.
Mats Electronics has ICs 1-800-628-1118
