Precision tv model number ptf21r99 not showing bright it is vary dark


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Precision tv model ptv2148


Vertical scan output section circuit fault. Check all the electrolytic capacitors there, and replace the faulty. Horizontal scan output is OK.

No picture or sound. Red light blinking four times on sony bravia tv. Suspect power supply problem?


Red light blinking 4 times on Sony bravia TV.This is the problem of INVERTER BOARD.The inverter board has to be replaced.Every Sony bravia tv has a particular model number and the Inverter board part number depends on model number of the tv. As you have not mentioned the model number so the exact part number of the inverter board is hard to tell.But you can get the required inverter board part for your tv from www.partstore.com ----------- Thanks. Keep updated for any more query. You can rate thissolution and show your appreciation.

Magnavox projection TV - Sound cuts off when changing channels.


Yea. Your model FP5210 is much older than one with digital SSB board. Still would think that the mute is being activated; probably by the ucontroller/cpu IC.

It does sound like you have a short on the power supply load. Most likely in the horizontal circuit. (Deflection board)
There is a company called PTS (Precision Tuner Service) that may be able to repair the circuit board.
You can look them up on the internet and call and ask them if they can repair this board. It is most likely the board that has the flyback on it. Have your model number and chassis number available when you call.

Sony KV-35s26 Chassis AA-2D problem


well I thought they had one there but it looks like they only have other chassis # and I have been looking to try and find your chassis # but the only ones ask for money to get it , but I have found some codes and remedy's for your chassi , you had a 5 blinking code which the diagnosis would be this
5 times, Diagnosis: White balance failure (Not balanced) Possible causes: Video out (IC7101, 7201, 7301) is faulty (CR, CG, CB board), CRT drive (IC309) is faulty (A board), G2 is improperly adjusted. Symptoms of the problem: No raster is generated, CRT cathode current detection reference pulse output is small.
if the blink code is now different then let me know what it is and i'll give you that diagnosis
