We've heard this before from appliance repair persons, auto repair persons, etc. "Go out and buy a new TV, this one will be too expensive to fix." And then it turns out to be a $5 part. If this fixes it, you just saved yourself $800 or so.

Do the standby light ON. If not check the 5V supply rail on the main board. If standby light is ON, and it blinks? If so, these 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. Viewing it in "Mosaic" or "Magazine" will make surf easy.

If there is distortion and noise, while using the TV, for on-air transmission, and there is no distortion or noise while using it AV, be sure that it tuner is faulty. Check the Ariel connection first, for discontinuity or loose contacts. If it found OK, replace the tuner. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter".

yes it may do but check other spareparts

The 5 blinks indicates a White Balance Failure. This involves checking voltages and components tied directly to the CRT. I would not suggest any attempt for self repair. The cost for this repair should not be significant. Figure a parts cost in the $30-$50 range at worst.

Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
Visit this site for more details. Type in the site name "Electro-help" either Google or Yahoo search box [not in the address bar of your browser], and click search.

Check the Hori output transistor near the FBT flyback transfomer.

Hello
The fault with your TV is with some loose contact inside it. Normally most Trinitron TVs shows this problem due to loose contact in the video output card. Video output card is pluged diretly to the picture tube base, and can be detachable. You can pull it out very carefully without damaging the pins of of the picture tube. Most of the components in this board will heat up during working. Repeated heating and cooling will make the solder joints of the most heated components to get loose contacted. Normally, these loose contacts are very difficult to detect because they will be microscopic. Just do as what we do for this type of fault.
Resolder most of the suspected solder terminals, with applying a little more solder, without making any solder bridge in between the solder terminals. This will solve the problem of your TV. OK.

As it has a tube, there seems no actual reason for that. The glass cannot change optical characteristics nor the coating on the inside of the tube. Maybe it is an optical illusion.

We would be happy to help get that fixed right away. Thefirst thing we want to ensure is that all connected equipment is on. Since we know you are using a coax cable to connect the receiver toTV1, check the receiver's back panel for the output name. If your receiver hasa "TV CH 3/4 out":Tune TV to channel 3 or channel 4, if it is labeled "Home Distribution": TuneTV to channel 62 or 75. We also want to ensure that the TV and thereceiver are connected properly, please visit this link to for moreinformation: http://www.dishnetwork.com/SupportSection/setup-receiver-totv.Once we have made sure everything is connected properly, unplug receiver for 10seconds then plug it back in, this will reset the receiver. If we are still notgetting a picture connect another component (VCR, DVD Player, etc.) to the sameTV, using same cable, same input, and same channel to see if it works. If youget a picture with the other component give us a call at 1-800-333-DISH (3474)for some additional troubleshooting. If it doesn't work with the othercomponent then replace the cable that was used.

We hope these steps resolve the issue. We want to thank you for being a valuedDISH Network customer!

That means the EHT has exceeded 33KV and it will shut down.
Probably caused by a faulty/maladjusted power supply. Check the 135Volt rail.
Hope that helps.

This is an indication that you have a problem on the power supply section or on the load because of the following reasons :

1. Over Voltage - the regulator might be cycling on over voltage due to lack of load.

2. Over Current Protection - excessive load or faulty power supply cycling will

trigger the over current protection circuit.

3. High voltage - there might be an excessive high voltage or some other system detecting an out of regulation condition. However, in this case, there should be some indication that the deflection and HV is attempting to come up - momentary whine, static on the screen, etc.

4. Leaky Capacitor - a dried up main filter capacitor or other filter capacitor in the low voltage power supply that is producing an out-of-regulation condition. A bad filter capacitor on the output of a series regulator may result in excessive/drop of voltage causes your unit not to power up unless isolated.

5. A problem with the microcontroller, relay or its driver, or standby power supply.

This is not DIY and quite technical so I've advice you to look for a qualified technician or send it to repair shop to isolate the problem.


Thanks for using fixya.
